Protection
Input Current Input circuit breaker. Breaker protects the equipment only and is not a branch protection device. AC input connection should be made using a suitable branch protection device per local electrical code
Input Voltage Transients Surge protection to withstand EN50082-1 (IEC 801-4, 5) levels
Output Over Voltage Adjustable level constant voltage mode with programmable set point
Open Circuit & Over Temperature Automatic Shutdown
Input
