MEAN WELL MSP-200-24 is a single-output medical-type power supply rated at 24 V DC, 8.4 A and 201.6 W. The 38 mm low-profile enclosure uses free-air convection. Universal AC input, active PFC and remote ON/OFF are provided. This MSP-200 model also provides remote sense and a separate 5 V standby output. Medical isolation levels and leakage test conditions are specified below; final-equipment suitability requires integration assessment.

Model and Output
| Complete model / catalogue |
MSP-200-24; MSP-200 revision 2024-10-30. The final code identifies the nominal 24 V output. |
| Rated DC output |
24 V / 8.4 A / 201.6 W. Current range at nominal voltage: 0–8.4 A. |
| Voltage adjustment |
21.6–28.8 V using SVR1. Observe rated current and power when adjusting voltage. |
| Ripple and noise |
150 mVp-p maximum; 20 MHz bandwidth, a 12-inch twisted pair terminated by parallel 0.1 µF and 47 µF capacitors. |
| Voltage tolerance |
±1.0%; includes setup tolerance, line regulation and load regulation. |
| Line / load regulation |
±0.2% / ±0.5%, respectively. |
| Typical efficiency |
88%, under the default 230 VAC, rated-load and 25°C test conditions. |
The 200 series designation is not a promise of that wattage at every output voltage. Use this model’s 201.6 W rating together with its current limit and both derating curves.
Input, Timing and Low-load Consumption
| Input / frequency |
85–264 VAC or 120–370 VDC; 47–63 Hz AC. Full-range input with built-in active PFC. |
| Typical power factor |
>0.95 at 230 VAC and >0.99 at 115 VAC, at full load. |
| Typical AC input current |
2.2 A at 115 VAC; 1.1 A at 230 VAC. |
| Typical inrush current |
35 A at 115 VAC; 70 A at 230 VAC. The block diagram includes active inrush-current limiting. |
| Short-duration input withstand |
300 VAC surge input for 5 seconds, as the feature list states. This does not extend the continuous 264 VAC input limit. |
| Setup / rise at full load |
230 VAC: 1000 / 50 ms; 115 VAC: 2500 / 50 ms. |
| Typical hold-up at full load |
16 ms at 230 VAC; 16 ms at 115 VAC. |
| No-load input power |
<0.5 W with RC+ and RC− shorted so that the main output is OFF, as specified in note 6. |
Unless otherwise stated, specifications are measured at 230 VAC input, rated load and 25°C ambient.
Protection
| Short circuit / overload |
Short-circuit and overload protection; threshold 105–135% of rated output power. Constant-current limiting, with automatic recovery after the fault is removed. |
| Over-voltage |
30–34.8 V; output shutdown, with re-powering required to recover. |
| Over-temperature |
Output shutdown with automatic recovery after temperature decreases. |
Protection thresholds are fault-response limits, not continuous or peak-output ratings.
Remote Control and Power Connections
| Remote ON/OFF logic |
CN100 pin 1 RC+ and pin 2 RC−: 4–10 VDC or open = ON; 0–0.8 VDC or short = OFF. |
| AC / earth terminals |
Terminal 1: AC/L; terminal 2: AC/N; terminal 3: FG protective earth. |
| DC output terminals |
Terminals 4–5: −V; terminals 6–7: +V. Use the numbered mechanical drawing for polarity. |
| CN100 signals |
1 RC+; 2 RC−; 3 AUX; 4 AUXG; 5 +S; 6 −S. |
Use the remote-control logic specified for this family; it must not be inferred from another MSP series.
Remote Sense and Auxiliary Output
| Remote sense |
CN100 pin 5 +S connects to the positive load terminal; pin 6 −S connects to the negative load terminal. Twist +S and −S together to reduce noise pickup. Maximum line-drop compensation: 0.5 V. |
| Standby specification |
5 V at up to 0.3 A; tolerance ±5%; ripple 50 mVp-p maximum. The function table states 4.75–5.25 V. |
| Auxiliary connections |
Pin 3 AUX is referenced to pin 4 AUXG. AUXG is isolated from the main +V and −V output terminals. |
| Auxiliary behavior |
The auxiliary output includes built-in ORing diodes and is not controlled by the main-output remote ON/OFF function. |
Connect sensing leads at the load as shown on PDF page 5. The auxiliary ORing statement does not establish a main-output active-current-sharing function for MSP-200.
Cooling, Derating and Environment
| Cooling |
Free-air convection; keep ventilation openings unobstructed. The specified curves are for horizontal mounting. |
| Working temperature / thermal load |
−40°C to +70°C, subject to derating. The horizontal curve shows 100% load through +40°C, then falls to 40% at +70°C. |
| Input-voltage load curve |
At 60 Hz, the graph rises from 80% load at 85 VAC to its full-load plateau at 100 VAC, continuing to 264 VAC. Apply this percentage to the model’s own output rating. |
| Altitude derating |
For this fanless model, reduce allowable ambient temperature by 3.5°C per additional 1000 m above 2000 m. This adjustment is not an independently specified maximum operating altitude. |
| Humidity / storage |
Working: 20–90% RH, non-condensing. Storage: −40°C to +85°C, 10–95% RH. |
| Temperature coefficient |
±0.03%/°C over 0–50°C. |
| Vibration |
10–500 Hz, 5G; 10 minutes per cycle, 60 minutes along each X, Y and Z axis. |
Input and ambient derating apply together. The maximum working temperature is not a full-load guarantee.

These MOOP and leakage statements describe the supply under the stated tests; they do not establish MOPP, a patient-applied-part classification, or compliance of a complete medical device. The MSP-200 isolation-level row does not assign a separate secondary-to-earth MOOP level.
The manufacturer’s EMC tests mount the unit on a 360 × 360 mm metal plate, 1 mm thick. As this supply is a component of final equipment, reconfirm EMC compliance after integration.
Mechanical Installation, Connectors and Weight
| Body dimensions / case |
199 × 98 × 38 mm (L × W × H), general tolerance ±1 mm; case drawing 902E. The 38 mm height is the low-profile / 1U feature stated by the manufacturer. |
| Terminal projection |
The mechanical drawing marks a terminal projection of 13 mm maximum beyond the body; allow this additional connection clearance. |
| Mounting-hole callouts |
4-M3; 3-M3. No thread-depth number is given beside these MSP-200 callouts; select mounting screws from the applicable drawing and installation requirements. |
| Adjustment / indicator |

| Control connector as printed |
CN100: HRS DF11-6DP-2DS or equivalent. Mating housing: HRS DF11-6DS or equivalent. Contact: HRS DF11-**SC or equivalent. |
| Connector selection |
Mating housing is a printed abbreviated code; the contact has a literal ** placeholder. Final order codes require contact/wire and connector selection. The printed mating-part references identify compatible connector families; they do not state that a mating housing, contacts or cable are supplied. |
| Catalogue unit packing reference |
0.77 kg per unit = 770 g. The complete PACKING entry is 0.77 kg; 18 pcs / 14.9 kg / 0.87 CUFT; the carton weight is not the individual unit weight. |
Use the full case drawing on PDF page 4 for hole positions, slots and terminal layout. No separate MEAN WELL bracket, cover or cable order code is listed on these MSP-200 pages.

| MTBF reference |
1609.5 K hours minimum under Telcordia SR-332 (Bellcore); 186.2 K hours minimum under MIL-HDBK-217F at 25°C. These are reliability calculations, not a guaranteed operating lifetime. |
| Manufacturer warranty statement |
The catalogue lists a five-year warranty, subject to applicable manufacturer terms. |
