The relay XUF2 of the easy PROFESSIONAL LINE is a digital relay for voltage and frequency supervision of 1-phase or 3-phase systems and provides protection for electrical power generators and general equipment against in-admissible undervoltage or overvoltage as well as against frequency changes.

In addition it is possible to supervise the phase sequence.

The XUF2 is compliant with IEC 60255-1.

Voltage and Frequency Protection. 100Vac, 110Vac, 230Vac, 400Vac (Rated voltage selectable via DIP settings).

Accuracy: Voltage precision 1% for Un = 100 V / 110 V / 230 V / 400 V (phase to phase Voltage) and (phase to ground Voltage) 

Frequency supervision =0.1% if phase to phase voltage is measured.

Frequency supervision =1% if phase to neutral voltage

XUF2 (DIP setting for 50 Hz / 60 Hz and for Vn = 100 V / 110 V / 230 V / 400 V) – ANSI 27, 59, 81O, 81U
