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
62.5-63 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.
Insulation Strength
Input to Chassis: 2KV AC for 1 min, 12mA - No dielectric breakdown
or flashover
Input to Output: 2KV AC for 1 min, 5mA - No dielectric breakdown or
flashover
Output to Chassis: 500V AC for 1 min, 5mA - No dielectric breakdown
or flashover
Application Scenarios
This module is an ideal power solution for:
