MEAN WELL RSP-100-7.5 is a single-output enclosed AC/DC power supply rated at 7.5 V DC, 13.5 A and 101.25 W. It uses active PFC and free-air convection in a 30 mm-high enclosure; available load depends on input voltage and ambient temperature.

The printed model encoding defines series, power designation and output voltage. It does not define a separate remote-control option suffix for this model. Remote-control connector information is listed separately below.

| Rated output current |
13.5 A |
| Output current range |
0 to 13.5 A |

Unless otherwise specified, parameters are measured at 230 VAC input, rated load and 25°C ambient.
Ripple and noise: 20 MHz bandwidth; 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors.
Voltage tolerance includes setup tolerance, line regulation and load regulation.
Use the voltage-adjustment control shown in the mechanical drawing within the stated range. Adjustment does not authorize exceeding the listed current or power ratings.
For this output-voltage version, the datasheet strongly recommends that external output capacitance should not exceed 5,000 µF.

>0.93 at 230 VAC; >0.98 at 115 VAC |
| Typical AC input current |
1.1 A at 115 VAC; 0.55 A at 230 VAC |
| Typical cold-start inrush |
30 A at 230 VAC |

The input-voltage derating graph is specified at 60 Hz: 80% load at 85 VAC, rising to 100% at 100 VAC and remaining at 100% through 264 VAC. Apply this limit together with temperature derating; the full input range is not a full-power rating at every voltage.
Protection
| Listed protection functions |
Short circuit, overload, overvoltage and overtemperature |
| Overload threshold |
105% to 135% of rated output power |
| Overload response |
Constant-current limiting; automatic recovery after the fault condition is removed. |
| Overvoltage threshold |
8.25 to 10.13 V |
| Overvoltage recovery |
Output shutdown; reapply input power to recover. |
| Overtemperature recovery |
Output shutdown; automatic recovery after temperature decreases. |
The overload threshold is a protection characteristic, not a continuous overload or short-duration peak-power operating rating.
Operating Conditions and Derating
| Working ambient temperature |
-30 to 70 °C; apply model-specific derating |
| Cooling |
Free-air convection; horizontal mounting in the derating graph |
| Full-load temperature plateau |
Through 45°C under the applicable input conditions |
| High-temperature derating endpoint |
60% load at 65°C for this output-voltage group |
| Working humidity |
20% to 90% RH, non-condensing |
| Storage temperature / humidity |
-40 to +85°C; 10% to 95% RH, non-condensing |
| Temperature coefficient |
±0.05%/°C over 0 to 50°C |
| Vibration |
10 to 500 Hz; 2 G; 10 min/cycle; 60 min each along X, Y and Z axes. |
| Overvoltage category III |
Up to 2,000 m under EN61558, EN50178, EN60664-1 and EN62477-1 |
Follow the complete temperature curve between the stated plateau and endpoint. The working-temperature range does not mean full load at every temperature; do not extend the voltage-group curve beyond its plotted endpoint.
Above 2,000 m, reduce ambient-temperature limits by 3.5°C per additional 1,000 m for these fanless models.
These pages specify overvoltage category III up to 2,000 m but do not state a separate maximum operating altitude. Do not extend the category III claim above 2,000 m.

Use the complete mechanical drawing for hole positions and clearances. Mounting callouts are not quantities of included screws. L=4 mm is the printed thread-depth callout; these pages do not specify tightening torque or wire gauge.
FG is protective earth. Observe the separately assigned AC input and DC output terminals; repeated -V or +V terminals belong to the same single output.

The mechanical drawing marks the remote-control connector as optional. Confirm the actual connector provision before wiring; do not assume that a mating housing, crimp terminals or a cable assembly is included.
The connector names above are transcribed as printed. These pages do not provide any additional pole-count suffix, exact supplied quantity, open-circuit default, permitted control current or maximum cable length. Do not complete abbreviated part numbers by borrowing codes from another series.
No separate dedicated bracket, terminal-cover or cable-kit order code is specified in these pages. Use only separately verified compatible accessories; the mounting drawing alone does not establish their supply or compatibility.
