Product description

 

Available 4th quarter 2022

The grid decoupling relay UFR1002IP is the "big brother" of the UFR1001E and monitors voltage and frequency in three-phase and AC grids.

With a color LCD display (German/English) and joystick, it is even easier to operate than the UFR1001E. Measured values and settings are clearly displayed. The device can be programmed, updates installed and the alarm memory read out via the integrated IP interface. The real-time clock (with power reserve) simplifies the traceability of the alarms. Up to 1,200 V can be monitored in conjunction with the VG1200 coupling device. The device has a two-channel, single-fault-safe design and thus meets the requirements of VDE-AR-N 4105:2018-11. The function of the connected switch is monitored. If monitoring is activated, the device does not switch on again if a switch-off error is detected.

Limit values for different applications are preset. Where permitted, they can easily be changed. If the nominal voltage is changed, the device automatically adjusts the limit values that have already been set. With the standby input, a remote shutdown can be implemented, e.g. with a ripple control receiver.

 

Monitoring of

  • Under/over voltage 15-520V (with ZIEHL VG1200 coupling device up to 1,200 V)
  • Under/over frequency 45-65 Hz
  • Voltage quality (10-minute average)
  • Vector shift 2-65°
  • ROCOF, rate of change of frequency df/dt 0.100...5.000 Hz/s
  • Zero voltage U0 (ANSI 59v0)
  • passive anti islanding protection

  • automatic adjustment of the switching points when the nominal voltage is changed
  • Alarm counter for 100 alarms (with trigger value, cause and date/time, time of restart)
  • 3 programmable digital inputs
  • Standby counter and timer with standby on/off date/time
  • Test and simulation function with measurement of switch-off times
  • Sealing option and code protection for settings
  • Interface ethernet TCP/IP, values available via modbus TCP
