Arga Battery Monitor Panel Mount

The Arga Battery Monitor Panel Mount from Electroswitch monitors battery voltage and ground fault detection for DC systems. A LED display identifies alarm conditions in addition to audible alarms. Easily calibrate and set alarm thresholds through the front panel menu.

Alarm functions: battery voltage, ground fault detection, AC power loss, ripple voltage, ripple current, high impedance and predictive corrosion detection.

Remote monitoring and reporting is ideal for multiple and distant locations. The Arga Battery Monitor Panel Mount supports Serial DNP3.0, Modbus and RS485 communications.
