Protection Features
Automatic Current Limiting
Once the output current reaches the set current limit, the module automatically switches to constant current operation, preventing any further increase in output current.
Overvoltage Protection
The module features software overvoltage protection, with configurable overvoltage alarm settings that can be set to initiate output shutdown.
Short-Circuit Protection
In the event of an output short circuit, the module enters a self-protective foldback mode to prevent damage, and automatically resumes normal operation once the fault is cleared.
