FURTHER INFORMATION
  • Output relay will operate to ON (pin 1 & pin 3 close) when power is applied to unit normally, and simultaneously detect if supplied power voltage rang, and phase in correct sequence for three phase type.
  • 5% to 20% Knob-adjustable separately for over voltage and under voltage. If voltage is over or under than the setting voltage for over 3 second, then the output relay will be released to its original position (pin 1 & pin 4 close).
