Output Protection

  • Short circuit
  • Single Phase Preventor
  • Over-current electronic protection
  • Incase output feedback is disconnected or loose connected; it detects the failure and display shows FAIL and Output goes to minimum.
  • Overload protection is provided in case load current exceeds the set limit to safeguard the entire stabilizer. Once the overload situation occurs it switches off the system and displays “HI” current and it resets when load is reduced and “SET” button is pressed.

Network Input Protection
Over-current thermal fuse and instant over-voltage protection
