Short answer
The Mean Well RSP-200 is a 200 W fanless switching power supply with an 88–264 VAC universal input and built-in active PFC. The 5 V model delivers 40 A (200 W); the series spans twelve rails from 2.5 V to 48 V in a 215 × 115 × 30 mm 1U chassis cooled by free air convection, with optional conformal coating (RSP-200-□CC variants), a 3-year warranty and EN 61000-3-2 harmonic compliance. Against the value-line LRS-200 at the same 40 A rating, the RSP-200 is the unit you pick when harmonics, grid freedom and tender paperwork matter.
What Is the Mean Well RSP-200 Switching Power Supply?
The Mean Well RSP-200 is a 200 W single-output enclosed AC/DC switching power supply (SMPS) that converts an 88–264 VAC mains feed into one regulated DC rail. The series carries twelve rails from 2.5 V to 48 V, with the screen-relevant 5 V model rated at 40 A / 200 W. Cooling is by free air convection alone — no fan, no dust intake, no bearing to service — inside a perforated 215 × 115 × 30 mm 1U chassis weighing 0.72 kg.
The RSP line’s signature is the active PFC front end: power factor above 0.95 at 230 VAC and above 0.98 at 115 VAC at full load, with EN 61000-3-2 and EN 61000-3-3 harmonic compliance listed on the datasheet. Every unit ships with a 3-year warranty and a published MTBF of 224,500 hours minimum (MIL-HDBK-217F, 25°C), and harsh-site builds are covered by the factory’s conformal-coated □CC variants.
40 A in silence
A 200 W rail with zero acoustic output — the pick for churches, studios and conference walls where a fan would be heard in the quiet moments.
Harmonics-legal by design
Active PFC plus EN 61000-3-2/-3 compliance keeps commercial European installs on the right side of the harmonic limits that non-PFC supplies fail.
Twelve-rail coverage
2.5 V and 4 V below the LRS ladder, 48 V above the screen rails — one chassis family covers the whole bill of materials.

Field notes before you buy
First, input range: the datasheet specifies 88–264 VAC while the production nameplate reads 100–240 V, 2.5 A (the photo below shows a 24 V unit) — design around 100–240 V nominal and apply the datasheet’s low-input derating (Note 4) below that. Second, the hold-up time is 8 ms — plan a UPS for blackout-prone sites rather than relying on ride-through. Third, over-temperature trips at 110°C on the 13.5/15 V models but 100°C on the 24–48 V models ( sensed on the output choke heatsink), so the higher rails need the airflow more.
Production nameplate: INPUT 100–240 VAC, 2.5 A · OUTPUT 24 V, 8.4 A · +V ADJ trimmer and R.C. pads at the end of the block
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-200 5 V Rail Carry?
Apply the industry-standard 80% loading rule and the RSP-200-5 gives you two budgets:
Power budget
200 W × 80% = 160 W usable per unit
Current budget
40 A × 80% = 32 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-200-5 at 160 W |
|---|---|---|
| Indoor P2.5 module (320 × 160 mm) | ~10–15 W | ~10–16 modules |
| Rental P3.91 module (250 × 250 mm) | ~15–20 W | ~8–10 modules |
| Outdoor P4.81 module (250 × 250 mm) | ~20–30 W | ~5–8 modules |
| Receiving card (Novastar / Colorlight class) | ~3–5 W | Shares the same 5 V rail |
One RSP-200-5 therefore covers a 500 × 500 mm indoor cabinet with room to spare; denser bays step up the RSP ladder — the 300 W Mean Well RSP-320 at 60 A — with the full derating math in our power consumption walkthrough.
Why Does the Mean Well RSP-200 Stay Fanless at 200 W?
At 200 W, most industrial supplies reach for a fan; the RSP-200 spends its thermal budget on surface area instead. The perforated honeycomb cover and fin field dump heat by convection alone, and the datasheet holds the −30 to +70°C working window with a derating curve at the top of the range. Three reasons that matters in a screen cabinet:
Nothing to hear
Churches, studios and control rooms hear the screen, not the power bay — there is no fan whine rising as the wall warms up.
Nothing to clog
Road dust, desert sand and stage haze never get pulled through the electronics — the failure driver that ages fan-cooled rental fleets early.
Nothing to schedule
No two-year fan-swap cycle — the supply’s service schedule matches the screen’s, and the 3-year warranty covers the whole window.
The 1U 30 mm profile keeps the power bay shallow enough for slim fixed cabinets, and the sealed convection path is why this platform survives sites that eat fan-cooled units.
Which Input Grids Can the Mean Well RSP-200 Run On?
The 88–264 VAC universal window spans 110–120 V and 220–240 V networks alike, with the active PFC holding power factor above 0.98 at 115 VAC and the factory curve giving full rated load from around 115 VAC upward (Note 4 covers derating below that):
| Grid | Verdict on the RSP-200 |
|---|---|
| 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+ — no transformer caveat for these grids |
| 88–100 V (brownout-prone 100 V grids) | Runs, but derate the load per the factory curve (Note 4) |
The wide window plus PFC is also what makes this unit generator-friendly: event power, long cable runs and lossy temporary distribution keep a corrected input calmer than a bare rectifier front end.
Which of the Twelve Mean Well RSP-200 Rails Fits Your Screen?
Every rail ships in the same fanless 1U chassis at the same universal input — only the DC bus changes:
LED screen bays: 5 V / 40 A
The RSP-200-5 feeds standard modules and receiving cards; a 160 W budget covers a 500 × 500 mm indoor cabinet outright.
Low-voltage specialty: 2.5 / 3.3 / 4 V
Common-cathode energy-saving work down to 2.5 V (read our common cathode LED technology explainer) at 40 A across all three low rails.
Signage and control: 7.5–48 V
Seven rails from 7.5 V to 48 V at up to 90% efficiency and ±0.5% load regulation cover signage, controllers and industrial buses.
Mean Well RSP-200-5 vs LRS-200-5: Is the PFC Upgrade Worth It?
This is the same-brand duel at identical output — both Mean Well units deliver 5 V at 40 A / 200 W, both are fanless, and screens mix them freely. The difference is what sits between the wall and the converter:
- Power factor: the RSP-200-5 corrects its input (PF > 0.98 at 115 VAC); the LRS-200 has no PFC stage — its own page notes it does not meet EN 61000-3-2, the harmonic limit that matters on European commercial installs.
- Rail coverage: twelve rails down to 2.5 V on the RSP-200 versus eight rails from 3.3 V on the LRS-200.
- Documentation: the RSP-200 publishes an MTBF figure (224.5K hours, MIL-HDBK-217F) and lists EN 61000-4 immunity testing to light-industry criteria A.
- Price: the LRS-200 stays the value pick — the RSP premium buys the PFC stage and the compliance paperwork, nothing else.
| Parameter | Mean Well RSP-200-5 | Mean Well LRS-200-5 |
|---|---|---|
| Output | 5 V / 40 A / 200 W | 5 V / 40 A / 200 W |
| PFC | Active, PF > 0.98 at 115 VAC | None |
| EN 61000-3-2 harmonics | Compliant (datasheet listed) | Not compliant (stated on its page) |
| Rails in series | 12 (2.5–48 V) | 8 (3.3–48 V) |
| Cooling | Fanless convection, 30 mm | Fanless convection |
| Efficiency (5 V rail) | 87% | Check the LRS-200 page |
For the cross-brand angle at the same 40 A class, the CZCL A-200AC-5 (190–264 VAC, no PFC, 26 mm) is covered on its own page — and note that both the RSP-200-5 and LRS-200-5 accept 110 V grids where the CZCL unit cannot.
Full detail on the value-line sibling lives on the Mean Well LRS-200 switching power supply page; the CZCL A-200AC-5 LED switching power page covers the third option.
How Does the Mean Well RSP-200 Fit the RSP-150 and RSP-320 Ladder?
Within the RSP line, the three screen-relevant members form a clean current ladder on the same universal-input, PFC, 3-year-warranty platform:
RSP-150 · 30 A / 150 W
The compact entry, 199 × 99 × 30 mm, with remote ON/OFF control — a 120 W budget for single cabinets.
RSP-200 · 40 A / 200 W
This unit: the same fanless 30 mm format grown to 215 × 115 mm, a 160 W budget, and twelve rails including 2.5 V.
RSP-320 · 60 A / 300 W
The cabinet workhorse with a speed-controlled fan — a 240 W budget that covers a 500 × 1000 mm indoor bay outright.
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-200 Safely?
The 9-pin terminal block and dual-side M4 mounts define the wiring workflow:
Terminal side with the +V ADJ trimmer, and the mounting flanges that take the M4 screws
| Pin | Assignment |
|---|---|
| 1 / 2 | AC/L · AC/N |
| 3 | FG (frame ground) |
| 4–6 | DC output −V |
| 7–9 | DC output +V |
1 · Mount on both side flanges
Four M4 screws per side (L = 3–5 mm per the factory drawing) into the cabinet power-bay rails, honeycomb cover unobstructed for convection.
2 · Wire AC, DC and ground
AC into pins 1–2, module and receiving-card bus across pins 7–9 (+V) and 4–6 (−V), FG bonded to cabinet earth. Check polarity with a meter before the first power-up.
3 · Set the rail with +V ADJ
Trim to 5.0 V (adjustable 4.5–5.5 V) at the far end of the DC bus under load, then confirm each cabinet measures the same within a few tenths.
4 · Respect the thermal map
Full load to ~40°C ambient on the factory derating curve, derating above that; the higher rails trip over-temperature at 100°C on the choke heatsink, so leave the convection path clear.
5 · Load-test and verify
Run a full-white pattern for ten minutes, feel for hot spots, confirm the LED indicator stays lit, then re-torque the terminals before closing the cabinet.
Two protection behaviors to brief your crew on
Overload (105–135%) trips into hiccup mode and recovers on its own when the fault clears. Over-voltage does not: an OVP trip latches the output off until the unit is re-powered — cycle the AC feed, then find 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 ladder.
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-200 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
Hiccup cycling reads as “random” dead cabinets; a latched OVP reads as dead-until-repower. Measure the rail during the dropout before replacing modules.
How Much Does the Mean Well RSP-200-5 Cost?
Authorized-distributor pricing sits at $55.21 for a single unit, $53.00 at five-plus and $51.90 at ten-plus (RS Components US, observed September 2026), with conformal-coated □CC variants running higher. Volume pricing for screen-production quantities steps down from there — Mean Well packs this series 15 pieces to a carton.

Mean Well RSP-200 Switching Power Supply: Frequently Asked Questions
Can the RSP-200-5 run on a 110 V outlet in the US?
Yes. The 88–264 VAC universal input carries full rated load from around 115 VAC upward; only the 88–100 V band asks for the derating the factory curve specifies (Note 4). No step-up transformer is needed for US, Canadian or Japanese grids.
How many LED modules can one RSP-200-5 drive?
At the 80% loading rule: 160 W or 32 A usable. A typical indoor P2.5 module draws about 10–15 W of average program material, so one unit covers roughly 10–16 such modules plus the receiving card — verify against your module’s datasheet and brightness profile.
Does the RSP-200 have a fan?
No — the datasheet specifies cooling by free air convection in the perforated 1U 30 mm chassis. It runs silently and does not ingest dust, with a −30 to +70°C working window and a derating curve at the top of the range.
What is the difference between the RSP-200-5 and the LRS-200-5?
The PFC stage. Both deliver 5 V at 40 A / 200 W fanless, but the RSP-200-5 corrects its input (PF > 0.98 at 115 VAC) and meets EN 61000-3-2 harmonic limits, while the LRS-200 states on its own page that it does not. The LRS-200 stays the value pick; the RSP-200-5 is the compliance pick.
Why did my RSP-200 shut off and not come back?
Check which protection tripped. Overload (105–135%) recovers by itself through hiccup mode, and over-temperature recovers once the choke heatsink cools. Over-voltage is the exception: it latches the output off until the unit is re-powered — cycle the AC feed, then find the upstream cause before restarting the screen.
What is the □CC suffix on some RSP-200 models?
It marks the factory conformal-coated build — a moisture and contaminant barrier on the PCB for coastal, dusty or high-humidity sites. Order the □CC variant explicitly; the standard unit ships uncoated.
What warranty and service life does Mean Well publish?
A 3-year warranty with a published MTBF of 224,500 hours minimum by MIL-HDBK-217F at 25°C, and 100% burn-in before shipment.
Can I parallel two RSP-200 units for more current?
No. The datasheet lists no current-sharing feature, so paralleled units will not divide load evenly. Split the bus by cabinet or step up to the RSP-320’s 60 A rail.
