UFR1002IP Voltage and Frequency Relay G99 & G99NI Compliant
The grid decoupling relay UFR1002IP is the latest addition to the G99 compliant relays alongside the UFR1001E. It monitors voltage and frequency in three-phase and AC grids with remote monitoring via an ethernet connection. Using the VG1200, there is the ability to be used on 1200V AC systems.

The UFR1002IP is compliant with G99 & G99NI and is approved on the ENA Direct Registry.
With a coloured LCD display and joystick for menu navigation, the UFR1002IP is very easy to use. The 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 1200 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. With the standby input, a remote shutdown can be implemented, e.g. with a ripple control receiver. |
