Security relay / under-voltage and overvoltage
KCV114x - SINGLE PHASE AC VOLTAGE GUARD
Generator Over/Under Voltage Guard, not affected by heavily distorted waveform
Complies with G59 requirements
Integral true RMS transducer
Fast analogue output (F-versions)
Optional DIN96 Slave Indicator with Status LEDs
True RMS measurement not affected by heavily distorted waveforms provides precision (1.0%) protection. Less than 50mS process time. The independent moving iron voltmeter accuracy is class 1,5.
The AC auxiliary voltage us supplied from the monitored voltage input.
Over and under voltage protection with a third relay (R3) that operates if either the over voltage relay (R2) and/or under voltage relay (R1) operate.
A timer will reset if fault is removed during count-down. Fixed hysteresis prevents relay "chatter". Full functionality control during power-up/power-down, with 500mS power-out reservoir.
User settable trip levels and delays (definite time delays). Colour of LEDs indicates alarm status. LEDs flash during Count-down.
The unit meets IEC60092-504 and the relevant environmental and EMC tests specified in IEC60068/60092 and IEC61000/60533 respectively, to comply with the requirements of the major Classification Societies.
