Notes:
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1 µF & 47 µF parallel capacitor.
- 3. Tolerance: includes set up tolerance, line regulation and load regulation.
- 4. Line regulation is measured from low line to high line at rated load.
- 5. Load regulation is measured from 0% to 100% rated load.
- 6. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to "EMI testing of component power supplies." (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
- 7. The ambient temperature derating of 3.5°C/1000m with fanless models and of 5°C/1000m with fan models for operating altitude higher than 2000m(6500ft).

Mechanical Specification
Case No.931A Unit:mm
Overall Dimensions:
The unit has dimensions of 78mm (Length) x 51mm (Width) x 28mm (Height). Key features include mounting holes and a terminal block.
Terminal Pin Assignment:
| Pin No. | Assignment | Pin No. | Assignment |
|---|---|---|---|
| 1 | AC/L | 4 | DC OUTPUT -V |
| 2 | AC/N | 5 | DC OUTPUT +V |
| 3 | FG |
Additionally, there is a +V ADJ. terminal and an LED indicator.
Block Diagram:
The block diagram illustrates the internal signal flow: AC input (I/P) passes through an EMI FILTER, then RECTIFIERS & FILTER, followed by POWER SWITCHING controlled by PWM CONTROL and O.L.P. (Over Load Protection). The output stage includes RECTIFIERS & FILTER and a DETECTION CIRCUIT, providing the final DC output (+V, -V). The FG (Frame Ground) is connected to the chassis.
Derating Curves:
Ambient Temperature Derating: The derating curve shows that the 3.3V model's load capacity begins to decrease around 50°C ambient temperature, while other models maintain full load capacity up to 70°C ambient temperature. The x-axis represents Ambient Temperature (°C) from -20 to 70, and the y-axis represents Load (%).
Output Derating vs. Input Voltage: This graph shows that the power supply operates at 100% load across the entire input voltage range from 88VAC to 264VAC, with no significant derating required within this range. The x-axis represents Input Voltage (VAC) from 88 to 264, and the y-axis represents Load (%).
