Battery voltages

Voltage measuring relay battery monitor 12V/24V/48 V

The voltage measuring relay monitors the DC voltage applied to terminals A1 and A2.
The relay picks up when the voltage to be measured is below the set value V< (battery is empty)
and the set delay time 0-10 minutes has elapsed.
This condition is indicated by the yellow LED lighting up.
The relay returns to its rest position as soon as the voltage to be monitored exceeds the set value at v> (charging end voltage).
