  • Supply voltage : 20-60VDC.
  • Output Contacts : One SPDT (C-N/O-N/C) Relay, Rating 5A at 250V AC
  • Indications : FAULT (UV): RED LED, RELAY ON:Green LED.
  • Keys:
  • SET : SET key, Press to enter into SET Mode
  • INC : Upward Arrow key, Press to increment the setpoint.
  • DEC : Downward Arrow key, To Decrement the setpoint.
  • Mounting : Door Mounting.
  • Dimensions : 96(L) * 96(W) * 110(D), mm.
  • Working :
    1] If the Input supply is within the range of the fault limits then On Timer starts decrementing on display & after Set On Time over Relay will be ON with RL indication glowing.
    2] If UV occurs in the supply then Relay will be OFF.If that particular fault is removed then ON Timer starts decrementing on display & after Set On & RL indication glowing.
