DMM-3 Battery Monitor-Microlog

  • The Microlog DMM-3 Battery Monitor is  designed to monitor the level of charge for 2  battery banks in measuring the total Battery Cells Voltages with great precision.
  • The voltage monitoring will help telling you the state and condition of your batteries, charging equipment and also when it's time to charge and stop charging.

Charge and discharge current monitoring: (as option)

  • With the shunt kit SWK-201 (sold separetely), the Microlog DMM-3  System will also monitor the intensity (Amperes) of incoming current from charging equipment such as alternators, wind generators or solar panels and/or, current consumed in your boat.
  • You can measure just charging or just discharging current if you prefer; or NET current circulation to your house bank.
