Application relay
DSP-VPFR Voltage Phase Relay
Voltage Phase Relay
Main Feature
  • Compact Size , MCU baesd
  •  Protection :Reverse Phase , Phase Loss
  •  LED indication for each protection trip
  •  Trip output : 1c(DP-ST)
  • Auto reset
  •  Phase loss protection :Available during Forward & Reverse
    • /ul>
Function and Usage
  • DSP-VPFR22  : 3 Phase, 160~300VAC
  • DSP-VPFR44  : 3 Phase, 300~480VAC
  • DSP-VPFR69  : 3 Phase, 590~770VAC
  • Usage
    • Reverse phase protection based on incomming voltage
    • Hoist, Crane, Movable Fan
  • Function
  • FWD-COM or REV-COM is energized accoding to initial detected state: the protection job is done normally
  • *Normal direction state :95-98 is closed & LED(Green) is turned on
  • *Reverse direction state:95-96 is closed & LED(G,Y,Red) is turned on
  • Phase loss in initial state or in working state :such state is shown by LED:L1-R, L2-G, L3-Y /the protection job is stopped
  • Usage
    • Reverse phase detector by voltage source
    • FWD-REV detection for Hoist, Crane, Lift,Portable FAN,etc.
  • Function
    • Trip output relay is energized according to initial detected state, but protection job is kept going on
      • Normal direction state :95-98 is closed & LED(Green) is turned on
      • Reverse direction state:95-96 is closed & LED(G,Y,Red) is turned on
    • • Phase loss for initial state or working state : phase indication by LED --> L1-Red, L2-Green, L3-Yellow/ Protection job is ceased
