Under-voltage monitoring relay TCV-W series

over-voltageDPCOAC/DC

- level and hysteresis adjustments - LED indicators for power supply, contact and reaction timer On application of the supply voltage with N.O. Mode selected, the output relay pulls in and the timing period ts starts Voltage monitor with no latch (auto reset) function At the end of ts when the measured voltage exceecs the window in either direction timing period tr starts. At the end of tr if the measurement still exceeds the set point the output relay changes ever. The output relay resets immediately when the monitored voltage reaches the hysteresis set value. Voltage monitor with latch (manual reset) function At the end of ts when the measured voltage exceeds the window in either direction, timing period tr starts. At the end of tr if the measurement still exceeds the set point the output relay changes over and remains in this condition, even when the measured voltage reaches the hysteresis set value. An external reset (S1) must be operated to reset the relay. supply voltage variation - nominal voltage +10% / -15% frequency range - 48- 63 Hz duty cycle - 100% start surge delay - 0 - 10s reaction time - 0 -5s reset time - < 1 00ms
