MEAN WELL RSP-200-27 is an enclosed single-output AC/DC switching power supply rated at 27 V DC, 7.5 A and 202.5 W. It accepts 88 to 264 VAC or 124 to 370 VDC and includes active power-factor correction. Cooling is by free air convection. Output availability depends on the model-specific input and temperature limits.

Unless otherwise specified, parameters are measured at 230 VAC input, rated load and 25°C ambient.
Ripple and noise are measured with 20 MHz bandwidth using a 12-inch twisted-pair wire terminated by parallel 0.1 µF and 47 µF capacitors. Voltage tolerance includes setup tolerance, line regulation and load regulation.
Use the specified current and power ratings for this complete model. The series number is a family power class, not a substitute for this model-specific output rating. Apply the input-voltage and temperature derating curves.
AC/DC Input, PFC and Timing

88 to 264 VAC, universal full-range input |
| DC input range |
124 to 370 VDC |
| Input frequency |
47 to 63 Hz |
| Power-factor correction |
Built-in active PFC |
| Typical power factor at full load |
>0.95 at 230 VAC; >0.98 at 115 VAC |
| Typical AC input current |
2.5 A at 115 VAC; 1.3 A at 230 VAC |
| Typical inrush current |
20 A at 115 VAC; 40 A at 230 VAC |
| Leakage current |
<1 mA at 240 VAC |
| Setup / rise time at full load |
1500 / 50 ms at 230 VAC; 3000 / 50 ms at 115 VAC |
| Typical hold-up time at full load |
8 ms at 230 VAC and 115 VAC |
| Input block-diagram function |
Active inrush-current limiting |
At low input voltage, reduce the output load according to the input curve. The 60 Hz graph reaches 100% load at 100 VAC and remains at 100% through 264 VAC; its 88 VAC endpoint is approximately 75%. These are graphical load limits, not extra input-voltage ratings.
Protection and Recovery
| Listed protections |
Short circuit, overload, overvoltage and overtemperature |
| Overload threshold |
105 to 135% of rated output power |
| Overload recovery |
Hiccup; automatic recovery after the fault is removed. |
| Overvoltage threshold |
32.9 to 38.3 V |
| Overvoltage recovery |
Output shuts down; reapply power to recover. |
| Overtemperature recovery |
Output shuts down; automatic recovery after the temperature falls. |
The overload range is a protection threshold, not an additional continuous rating or an authorized peak-power operating mode.
Cooling, Operating Conditions and Derating
| Cooling method |
Free air convection |
| Working ambient temperature |
-30 to +70°C, subject to derating |
| Temperature-curve mounting orientation |
Horizontal |
| Full-load temperature plateau for this model |

The upper working temperature is not a full-load rating. Apply thermal and input-voltage restrictions together and use the complete manufacturer curves for intermediate conditions.
For this fanless model, apply additional ambient-temperature derating of 3.5°C per 1,000 m above 2,000 m. The RSP-200 pages do not specify a maximum operating altitude.

Follow the complete drawing for mounting tabs, hole positions and clearance. Thread counts and L dimensions are drawing callouts, not supplied screw quantities. Do not infer a tightening torque or conductor size from the drawing.
The +V and -V groups are connections to the same single output, not independently rated output channels. Connect FG to protective earth and follow the specified AC and DC polarity.
Options and Connection Scope
| Conformal coating |
Optional, as listed by the manufacturer |
The family pages do not provide a complete order code or suffix for the conformal-coating option. Confirm the required ordering designation before selecting it; do not assume coating is included in this standard model.
No separate complete order code for a mounting bracket, terminal cover or connector kit is stated in these pages. Mounting features do not establish that such accessories are included.
The documented interface is the 9-position AC/DC power terminal block. No remote ON/OFF, remote-sense or DC-OK signal connection is specified for this model in these family pages.

The power supply is a component for installation in final equipment. The family EMC test note specifies a 360 × 360 × 1 mm metal plate. Reconfirm EMC compliance in the completed equipment; component approvals do not certify the whole end product.
Safety and EMC statements here follow the linked datasheet revision and its model restrictions. MTBF values are reliability estimates, not a guaranteed operating life.
The datasheet notes that some models may not carry the BIS logo; confirm the required marking with MEAN WELL sales.
