Arga Battery Monitor Portable Monitor Battery Voltage, Ground Faults and Alarm Outputs ARGA BATTERY MONITOR The Arga Battery Monitor Portable from Electroswitch is designed to be portable and self-containted for monitoring battery voltage, ground fault detection and alarm outputs in the field. 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 Portable supports Serial DNP3.0, Modbus and RS485 communications. Adjustable alarm threshold set points High / low battery voltage alarms ± Ground fault detection with alarm AC charger power loss High accuracy ± 0.2 VDC Open cell alarm Remote Monitoring and Reporting • Serial DNP3.0, Modbus, RS485: 2-wire standard, 4-wire optional • 4 dry contact alarm outputs • Analog current outputs (standard 4 to 20 mA) Additional Options Standard Outputs 50–180 VDC, 3VA (for 125 V battery) 100–360 VDC, 5VA (for 250 V battery) 36–72 VDC, 3VA (for 48 V battery) 30.83 KΩ ± 1% from each bus to ground (for 125 V battery) 60.50 KΩ ± 1% from each bus to ground (for 250 V battery) 15 KΩ ± 1% from each bust to ground (for 48 V battery) 0 to ± 199.9 VDC in 0.6" bright red LED digits and decimal point.
