The BMV 712 has been designed to minimize power consumption. The alarm relay therefore is a bistable relay, and the current draw remains low whatever the position of the relay.

Key Features

• Easy to install.
• Midpoint voltage monitoring.
• Very low current draw from the battery.
• Bi-stable alarm relay.

Other features

• Battery voltage, current, power, ampere-hours consumed and state of charge.
• Remaining time at the current rate of discharge.
• Programmable visual and audible alarm.
• Programmable relay, to turn off non-critical loads or to run a generator when needed.
• 500 Amp quick connect shunt and connection kit.
• Shunt selection capability up to 10.000 Amps.
• VE. Direct communication port.
• Stores a wide range of historical events, which can be used to evaluate usage patterns and battery health.
• Wide input voltage range: 9,5 – 95V.
• High current measurement resolution: 10 mA (0,01A).
• Additional input to measure voltage (of a second battery), temperature or midpoint voltage, and corresponding alarm and relay settings.
