Automatic current-limiting feature
When the output current exceeds the set output current limit, constant-current output is activated.
Output Overvoltage Protection
Equipped with software-based overvoltage protection, the overvoltage alarm can be configured to trigger an overvoltage shutdown.
Output short-circuit protection characteristics
After a short-circuit shutdown lasting 5 seconds, the rectifier attempts to restart; if short-circuit protection trips four times within 5 minutes, the rectifier will lock out and remain disabled.
The number of protections must not exceed four within five minutes; once the five-minute period elapses, the recovery count is reset.
