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 output will automatically shut down if the voltage exceeds 295 ± 15 VDC to protect connected equipment from damage.
Short-Circuit Protection: During an output short-circuit, the module self-protects to prevent damage. After the fault is cleared, normal operation is automatically restored.
