This is an installation manual for the SD series power modules produced by Shenhua. It introduces the features and usage of the SD series products.
This manual provides step‑by‑step instructions for installing the Shenhua SD series switch power supply module. It describes the five colour‑coded leads (red, black, gray, yellow, blue) and how to connect each to the original power circuit.
Precautions for remote‑shutdown wiring, temperature limits, and overload protection are also covered, along with voltage adjustment procedures and basic specifications of the module. This manual is written in Chinese.
| Voltage adjustment range | +90 V to 155 V |
|---|---|
| Output main voltage | Adjustable |
The module has five wires: red, black, gray, yellow, and blue.
The gray wire is the remote‑shutdown line; when it is connected to the primary ground it puts the power supply into standby mode.
Turn the voltage‑adjustment screw clockwise; one full turn raises the output voltage by about the amount indicated in the manual.
