Offgridtec Voltage monitoring 12V

The voltage measuring relay monitors the DC voltage applied to terminals A1 and A2.

Application:
Deep discharge protection and overcharge protection for AGM, GEL, and flooded batteries.

The relay activates when the voltage to be measured falls below the set value V< (battery is empty) and the configured delay time of 0-10 minutes has elapsed. This condition is indicated by the yellow LED lighting up. The relay returns to its resting position as soon as the monitored voltage exceeds the set value V> (end-of-charge voltage).
