Short answer
The Mean Well RSP-150 is a 150 W fanless switching power supply with a universal 85–264 VAC input and built-in active PFC. The 5 V model delivers 30 A (150 W); the series spans nine rails from 3.3 V to 48 V, all in a 199 × 99 × 30 mm chassis with remote ON/OFF control, 4 kVAC isolation, a 3-year warranty and a 2,253,900-hour Telcordia MTBF rating. It is the PFC-equipped, grid-agnostic member of the Mean Well LED-screen power set — and the one unit here that American, Japanese and Taiwanese 110–120 V walls can feed directly.
What Is the Mean Well RSP-150 Switching Power Supply?
The Mean Well RSP-150 is a 150 W single-output enclosed AC/DC switching power supply (SMPS) that converts a universal 85–264 VAC mains feed into one tightly regulated DC rail. The series ships nine rails — 3.3, 5, 7.5, 12, 13.5, 15, 24, 27 and 48 V — with the 5 V model rated 30 A, and it cools by free air convection with no fan at all, in a perforated 199 × 99 × 30 mm chassis weighing 0.6 kg.
Two engineering choices separate the RSP-150 from the rest of the Mean Well screens set. First, the active PFC front end (power factor above 0.93 at 230 VAC and above 0.98 at 115 VAC) — the same feature that makes the CZCL A-400JQ-5P special in its family, here in a 150 W chassis. Second, the built-in remote ON/OFF control on a JST connector, letting a timer or room controller switch the DC bus without breaking mains. Mean Well backs the platform with a 3-year warranty and a dual-method MTBF: 2,253,900 hours minimum by Telcordia SR-332 plus 290,700 hours minimum by MIL-HDBK-217F at 25°C.
Runs anywhere on earth
85–264 VAC universal input covers 110–120 V and 220–240 V grids alike — no narrow-window restrictions, no step-up transformer for US or Japanese sites.
Silent, sealed, serviceable
Fanless convection at up to +70°C, LED power-on indicator, and a remote ON/OFF pin pair for centralized or scheduled switching.
Certified beyond the screen market
UL 62368-1, TUV, CCC, EAC, BSMI, AS/NZS and IS13252 approvals plus EN 61000-3-2 harmonic compliance — the factory automation pedigree shows.

Factory mechanical drawing: 199 × 99 × 30 mm, Case 215A, 7-pin terminal plus CN1 remote
Universal input comes with one rule: read the low-voltage derating
The datasheet specifies 85–264 VAC, while the production nameplate reads 100–240 V, 1.9 A (the photo below shows both). The factory curve fills the gap: at 115 VAC and above the unit carries full rated load; on an 85–100 V grid the output derates to roughly 80% (datasheet Note 5 — “derating may be needed under low input voltages”). Also note OVP behavior: unlike the overload protection, an over-voltage trip latches until you re-power the unit.

The published ripple figures follow the same factory measurement discipline as the rest of the range — here is Mean Well’s own method video, the same habit our bench applies before any batch ships:
How Many LED Modules Can the Mean Well RSP-150 5 V Rail Carry?
Apply the industry-standard 80% loading rule and the RSP-150-5 gives you two budgets:
Power budget
150 W × 80% = 120 W usable per unit
Current budget
30 A × 80% = 24 A usable per unit
Mapped onto typical modules (average draws under normal program material — full-white patterns run higher, so verify against your module datasheet):
| Typical load | Average draw | Max per RSP-150-5 at 120 W |
|---|---|---|
| Indoor P2.5 module (320 × 160 mm) | ~10–15 W | ~8–12 modules |
| Rental P3.91 module (250 × 250 mm) | ~15–20 W | ~6–8 modules |
| Outdoor P4.81 module (250 × 250 mm) | ~20–30 W | ~4–6 modules |
| Receiving card (Novastar / Colorlight class) | ~3–5 W | Shares the same 5 V rail |
One RSP-150-5 therefore covers a 500 × 500 mm indoor cabinet outright; bigger bays step up the Mean Well ladder — the 400 W Mean Well NEL-400 or the 500 W LRS-600 — with the full derating math in our power consumption walkthrough.
Why Does the Mean Well RSP-150 Include Active PFC?
Power factor correction is the quiet feature that separates the RSP-150 from every budget LED supply in this comparison set. The active PFC stage shapes the input current draw so the supply looks resistive to the grid: PF above 0.93 at 230 VAC and above 0.98 at 115 VAC at full load. Three practical consequences follow:
Harmonics compliance
The datasheet lists EN 61000-3-2 and EN 61000-3-3 harmonic compliance — the class of requirement that matters on commercial and light-industrial installs in Europe.
Long cable runs and generators
A corrected input tolerates lossy distribution and generator power far better — event sites, temporary feeds and long AC runs keep cleaner DC on the other side.
More real watts per breaker
At PF ≈ 1 the supply draws 0.8 A from a 230 V wall at full load — a screen full of RSP-150 units loads breakers and cables predictably, with no reactive penalty.
The trade is historical, not technical: PFC circuitry adds a front-end stage, which is why Mean Well’s own LRS line omits it for cost and the RSP line exists. If your project never leaves a 230 V residential circuit, the LRS remains the value pick; the moment harmonics, generators or 115 V grids enter the picture, the RSP earns its premium.
Which Input Grids Can the Mean Well RSP-150 Run On?
All of them — with one derating rule attached. The 85–264 VAC window spans every common residential and commercial grid on the planet, and the unit carries full rated load from 115 VAC upward. Below that, the factory curve derates the output gradually to roughly 80% at the 85 V floor:
| Grid | Verdict on the RSP-150 |
|---|---|
| 220–240 V (EU, UK, Middle East, Asia, AU) | Full rated load; the design center the nameplate quotes (100–240 V) |
| 110–120 V (US, Canada, Japan, Taiwan) | Full rated load at 115 V+ — the only supply family on this site with no transformer caveat for these grids |
| 85–100 V (brownout-prone 100 V grids) | Runs, but derate the load to roughly 80% per the factory curve (Note 5) |
Two more environment notes from the datasheet: the unit is rated for over-voltage category III up to 2,000 m altitude and category II up to 5,000 m (above 2,000 m, apply the 3.5°C per 1,000 m temperature derating), and the −30°C to +70°C working window makes it the widest-temperature fanless chassis in this comparison set — though the 3.3–7.5 V rails begin derating near 40°C while the 12–48 V rails hold full load to 50°C, so check the curve for your rail before promising full output in a hot cabinet.

Which of the Nine Mean Well RSP-150 Rails Fits Your Screen?
Every rail ships in the same chassis at the same 85–264 VAC input — only the DC bus changes:
LED screen bays: 5 V / 30 A
The RSP-150-5 feeds standard modules and receiving cards; a 120 W budget covers a 500 × 500 mm indoor cabinet with headroom.
Low-voltage rails: 3.3 / 7.5 V
The 99 W 3.3 V rail serves common-cathode energy-saving work (read our common cathode LED technology explainer); 7.5 V covers specialty strings. Both derate from about 40°C ambient.
Signage and control: 12–48 V
12, 13.5, 15, 24, 27 and 48 V rails cover strip signage, controllers and telecom-style buses at ±1.0% tolerance on the top three rails.

Mean Well RSP-150-5 vs CZCL A-200AC-5: Which 5 V Supply Fits Your Cabinet?
The two 5 V workhorses on this site meet here from opposite philosophies — the CZCL unit wins on raw current, the Mean Well wins on grid freedom and paperwork:
- Input window: 85–264 VAC universal versus 190–264 VAC — only the RSP-150-5 can be plugged into a 110 V wall.
- Current class: the A-200AC-5 carries 40 A / 200 W against the RSP-150-5’s 30 A / 150 W — one CZCL unit feeds roughly a third more modules.
- Power factor: active PFC (PF > 0.98 at 115 V) with EN 61000-3-2 compliance versus no PFC stage.
- Control: the RSP-150-5 adds remote ON/OFF on CN1 — scheduled or centralized bus switching the CZCL unit cannot do.
- Documentation: dual-method MTBF (2.25M h Telcordia / 290.7K MIL-HDBK-217F) and a 3-year warranty versus a 2-year term.
| Parameter | Mean Well RSP-150-5 | CZCL A-200AC-5 |
|---|---|---|
| Output | 5 V / 30 A / 150 W | 5 V / 40 A / 200 W |
| Input window | 85–264 VAC universal (full load ≥115 VAC) | 190–264 VAC (220–240 V grids only) |
| PFC | Active, PF > 0.98 at 115 VAC | None |
| Cooling / height | Fanless / 30 mm | Fanless / 26 mm |
| Efficiency (5 V rail) | 87% | 88% |
| Remote control | CN1 remote ON/OFF | None |
| Warranty / MTBF | 3 years / 2,253.9K h Telcordia | 2 years / not published |

How Does the Mean Well RSP-150 Fit the LRS and NEL Families?
Mean Well’s three screen-relevant lines now divide the work cleanly, and the RSP-150 slots in as the compliance-and-control specialist:
LRS — the value line
Multi-rail from 150 W to the 500 W LRS-600; the LRS-150 covers the 12–48 V rails in the same fanless 30 mm format. No PFC, lowest cost.
NEL — the screen-native line
LED-only rails (2.8 / 4.2 / 5 V) with conformal coating standard and 80 A on the 5 V rail; the 400 W NEL-400 is the cabinet-volume pick.
RSP — the compliance line
Nine rails, active PFC, remote ON/OFF, 4 kVAC isolation and a 3-year warranty — the unit you spec when the site has generators, 115 V power, tender paperwork or scheduled switching.
On our own bench, serviceability is designed into the cabinet from day one — our stage-screen build runs a detachable PSU box so a failed unit swaps in minutes:
How Do You Install and Wire the Mean Well RSP-150 Safely?
The 7-pin terminal plus the CN1 remote pair define the wiring workflow:
| Pin | Assignment |
|---|---|
| 1 / 2 | AC/L · AC/N |
| 3 | FG (frame ground) |
| 4, 5 | DC output −V |
| 6, 7 | DC output +V |
1 · Mount on the side flanges
Four M4 screws per side (L = 4 mm per the factory drawing) plus the mid-case tab. Keep the perforated cover unobstructed — convection is the only cooling.
2 · Wire AC, DC and ground
AC into pins 1–2, module and receiving-card bus across pins 6–7 (+V) and 4–5 (−V), FG bonded to cabinet earth. Check polarity with a meter before the first power-up — reversed DC is the fastest way to destroy a receiving card.
3 · Optional: wire the remote control
The CN1 JST pair switches the output remotely: 0–0.8 VDC powers ON, 4–10 VDC powers OFF — wire it to a timer or room controller for scheduled dark hours without touching mains.
4 · Set the rail with +V ADJ
Trim to 5.0 V (adjustable 4.75–5.5 V) at the far end of the DC bus under load, then confirm each cabinet measures the same within a few tenths.
5 · Mind the output capacitance limit
On the 3.3/5/7.5/12 V models the datasheet caps external output capacitance at 5,000 µF — oversized buffer banks on the DC bus can trip the start-up circuit.
6 · Load-test and verify
Run a full-white pattern for ten minutes, feel for hot spots, confirm the LED indicator stays lit, and re-torque the terminals before closing the cabinet.
Two protection behaviors to brief your crew on
Overload recovers on its own — constant current limiting rides through the fault and resumes when it clears. Overvoltage does not: an OVP trip latches the output off until the unit is re-powered, so after an OVP event, cycle the AC feed and then look for the upstream cause. And as with every non-current-sharing supply, do not parallel outputs for more current — split the bus by cabinet or step up the rail.
When a unit does fail in the field, our LED display power supply diagnostics and replacement guide walks the test-and-swap workflow end to end.
What Problems Does a Failing Mean Well RSP-150 Power Supply Cause?
Power trouble wears disguises — check these three signatures before blaming a module or a control card:
Dim or uneven brightness, one cabinet
Aging output capacitors sag the rail under load; the cabinet’s corner looks tired while its neighbors shine. Full-white patterns make it obvious.
Flicker on camera or under load spikes
An overloaded or failing rail dips for a frame at a time. Flicker that tracks bright content points at the supply first.
Cabinet reboots or dead sections
Constant-current limiting reads as a dimmed bus rather than a hard off; a latched OVP reads as a dead cabinet until re-power. Measure the rail during the dropout before replacing modules.
How Much Does the Mean Well RSP-150-5 Cost?
Authorized-distributor pricing sits at $39.70 for a single unit and $37.80 each at five-plus (Mouser, observed September 2026), with independent distributors at $38.60 (Bravo Electro). Volume pricing for screen-production quantities steps down from there — Mean Well packs this series 24 pieces to a carton.

Mean Well RSP-150 Switching Power Supply: Frequently Asked Questions
Can the RSP-150-5 run on a 110 V outlet in the US?
Yes — it is the one supply in this comparison set built for it. The 85–264 VAC universal input carries full rated load from 115 VAC upward; only an 85–100 V supply asks for the roughly 20% derating the factory curve specifies. No step-up transformer needed for US, Canadian or Japanese grids.
How many LED modules can one RSP-150-5 drive?
At the 80% loading rule: 120 W or 24 A usable. A typical indoor P2.5 module draws about 10–15 W of average program material, so one unit covers roughly 8–12 such modules plus the receiving card — verify against your module’s datasheet and brightness profile.
Does the RSP-150 have a fan?
No — the datasheet specifies cooling by free air convection in the perforated 30 mm chassis. It runs silently and does not ingest dust, with a −30 to +70°C working window; note the 3.3–7.5 V rails begin derating near 40°C ambient while the 12–48 V rails hold full load to 50°C.
What is the remote ON/OFF control for?
The CN1 pin pair (JST XH connector) lets external logic switch the DC output: 0–0.8 VDC powers the unit ON, 4–10 VDC powers it OFF. Wire it to a timer, light sensor or room controller to darken the screen on schedule without switching mains.
What is the difference between the RSP-150 and the LRS-150?
The LRS-150 is the value line: no PFC stage, same fanless 30 mm format, focused on the 12–48 V rails. The RSP-150 adds the active PFC front end, the 3.3–15 V low-voltage rails, remote ON/OFF control, 4 kVAC isolation and a 3-year warranty. Choose LRS for cost, RSP for grids, harmonics and control.
Why did my RSP-150 shut off and not come back?
Check which protection tripped. Overload (105–135%) recovers by itself through constant current limiting, and over-temperature recovers once the case cools. Over-voltage is the exception: it latches the output off until you re-power the unit — cycle the AC feed, then find the upstream cause before restarting the screen.
What warranty and service life does Mean Well publish?
A 3-year warranty — a year more than the LRS and NEL lines carry — with a dual-method MTBF: 2,253,900 hours minimum by Telcordia SR-332 plus 290,700 hours minimum by MIL-HDBK-217F at 25°C.
Can I parallel two RSP-150 units for more current?
No. The datasheet lists no current-sharing feature, so paralleled units will not divide load evenly — one runs hot while the other idles. Split the bus by cabinet or step up to a higher-current single supply.
