The voltage- and frequency-relay UFR1001 monitors voltage and frequency in two- or three-phase networks with or without neutral and switches off rapidly when required.

The device can be easily adapted to the requirements of the carrier of the power network. With the integrated vector-step relay it can also monitor networks at synchronous generators. 

After selecting a basic program, for each relay limits can be programmed for over-/undervoltage and over-/underfrequency. In programs with vector-stepmonitoring, K2 is used for vectorstep only.

Applications are monitoring power-networks at great solarplants, in block power heating stations, also with synchronous generators (vector shift) or generally monitoring the quality in power networks at machines or power-supplies.

  • monitoring of over- and undervoltage 40…520 V
  • monitoring of over- and underfrequency 45…65 Hz
  • monitoring of quality of voltage (10-minutes-average)
  • monitoring of vector-shift 2…20 °, 1 or 3-phase
  • Switching-delay adjustable <0,05…60,0 s
  • Switching-back-delay adjustable 0…1000 s
  • Alarm-counter for up to 100 alarms (with measured value and reason)
  • Added time of alarm up to 999 hours. Displays the time, alarms have been active (while supply voltage applied only)
  • LEDs for alarms, allocation of values and states of relays
  • 2 output-relays, each for monitoring frequency and/ or voltage
  • function of relays (nc- or no -operating mode) programmable
  • interlocked switching or autoreset
  • input for Enable / Reset
  • easy programming by help of basic programs
  • Sealing of settings is possible
  • code-lock against manipulation of settings
  • universal power-supply AC/DC 24-270 V
  • housing for DIN-rail-mount, 70 mm wide, mounting height 66 mm
