CRISTEC presents its battery control accessory: the JBNUM-II battery monitor. The CRISTEC battery monitor is the only one on the market with a large graphic LCD display for optimum data reading: 62 x 44 mm (built-in backlight). Its version includes a 250A shunt to simultaneously control the voltage, amperage and remaining capacity of a battery bank (i.e.: servitude) as well as the voltage of two other battery banks (i.e., starting and thruster).


Product Overview

The batteries can be in 12, or in 24 or in 48V, see mixed.

By adding optional shunt kits it is possible to fully control 3 battery packs simultaneously (or the flow of power sources such as a wind turbine or solar panels – voltage & current) and 2 extra battery packs. This new battery gauge features an alarm that triggers when the preset low battery capacity threshold is reached and a dry contact for automatic control of a generating set.
