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
If the output voltage exceeds 60-63 VDC, the module automatically stops output to prevent damage to connected equipment.
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: 1600VAC 1 min 5mA (No dielectric breakdown or flashover)
Input to Output: 1600VAC 1 min 4mA (No dielectric breakdown or flashover)
Output to Chassis: 600VAC 1 min 4mA (No dielectric breakdown or flashover)
