Protection Features
- Automatic rate limiting feature: When the output current exceeds
the set current limit, the system maintains constant current output
without increasing the current
- Overvoltage protection: Features dual overvoltage protection for
both hardware and software
- Output short circuit protection: During an output short circuit,
the module automatically retracts to protect against damage and
resumes operation after fault clearance
