One spdt output relays.
The k8ak ph1 output contacts are normally operative.
Two spdt output relays 5 a at 250 vac resistive load.
Monitor overvoltages undervoltages phase sequence and phase loss for three phase 3 wire or 4 wire power supplies with just one unit.
Phase sequence and phase loss operation diagram note.
Phase loss cannot be detected on the load side because this detection is based on the.
Green relay output ry.
The relay will not operate if the input voltage drops below 70 of the minimum input value because l1 and l2 are also used to provide power.
Power on lock time lock 1 s or 5 s switched using dip switch indicators.
Output overvoltages and undervoltages using separate relays.
