The voltage measurement relais monitors the direct current at binding post A1 and A2.

Application:
Protection from deep discharge and overload  for AGM, GEL and lead acid batteries.

The relais starts working when the measured voltage sinks under a pre-defined value V< (battery is discharged) and the programmed deceleration time of 0-10min has run out. This is displayed by a yellow led warning light.
The relais switches back to stand-by mode when the monitored voltage exceeds the pre-defined value V> (end-of-charge voltage)
