Breakdown voltage between NMEA 2000 network interface and inputs: 2500 V RMS.Maximum allowed DC voltage on inputs (with respect to GND input): 40 V.Current measurement accuracy (see note below): ☐.5 %.The unit continuously monitors voltage, current (charge or discharge. It is supplied complete with a precision 200 AMP shunt and a prefabricated cable assembly to enable simple DIY installation. External shunt's nominal voltage drop (recommended): 75 mV Clipper BM-2 Battery MonitorThe BM-2 is designed to monitor performance of 12 volt lead acid battery systems with capacities of up to 600 Amp hours.External shunt rated current: 5.2500 A.For example, you can configure the Battery Monitor to automatically raise a sound or voice alert about low battery charge with the Alarm Button, or to turn some equipment on or off, or to start a genset to recharge the battery with the Circuit Control. The Battery Monitor can be configured to manage channels of an NMEA 2000 digital switching system, and/or trigger a digital alarm unit compatible with standard NMEA 2000 PGNs 127501/127502. The solar charge controller only knows current it is putting into the system. Device connection (Device's wire colours are in BOLD) A shunt based battery monitor is like an accountant for current going into and out of the battery.
BATTERY MONITOR WITH SHUNT SOFTWARE
The Device can be also configured over NMEA 2000 using installation description strings a PC gateway and software (like CAN Log Viewer or ActiSense NMEA Reader) may be required for this method. In addition, you can specify battery parameters such as nominal capacity and voltage, chemistry, etc. At minimum, you should specify drop voltage and maximum current for the connected shunt.
BATTERY MONITOR WITH SHUNT UPDATE
The Device incorporates a MicroSD card slot which allows using a standard FAT-formatted card to configure it and update its firmware. An amp-hour meter is an electronic measuring device that uses a precision shunt to calculate the amp-hours going in (charging) and coming out (discharging) a. It can be configured to use data from a NMEA 2000 thermometer connected to the battery to detect the charge state and health more accurately and report temperature along with voltage and current data. To operate as intended, it requires an appropriate external shunt (not supplied with the Device) shunts in the range from 5A to 1200A are widely available (please refer to Section V "Choosing a Shunt" of the User Manual). alternator, wind generator, etc.) or load (windlass, refrigerator, etc.), but it is primarily designed for monitoring a marine battery. The Battery Monitor can be used with any single DC source (i.e. nominal capacity and chemistry) to NMEA 2000 and can turn on the genset or warn when the battery state is critical. The device reports measured voltage and current, calculated health and charge state, and user-programmed static data (e.g.
