CruzPro VAF-65 3 Bank DC Power Management Instrument

The VAH60 Digital Battery Monitor provides accurate low cost digital instrumentation for three banks of batteries between 9.50 and 33.00 Volts.

Displays battery voltage for three banks and charging or discharge current and tells you how much battery capacity has been consumed and how much is remaining in your main house bank. It keeps track of all current entering and leaving the battery and applies the appropriate Peukert's and charge efficiency factors four times per second.

Displays current being delivered to or draining from the main house bank (-450 to +450 Amps, in tenths of an amp below 20.0 amps), the number of amp-hours remaining in the house bank (0 to 3000 Amp-Hours) or the percentage charge remaining in the house bank (0 to 100%).

Set Low and High voltage alarms for each battery bank independently and a Low Amp-Hours Remaining alarm for your main house bank. When activated, the built-in 85 dB alarm will sound and the display will flash.

Five levels of backlighting can be selected.

Calibrations can be altered using the front-panel switches for: Battery voltage (for each battery separately), battery current, charge efficiency, Peukert's exponent, battery bank capacity (in amp-hours), low and high voltage alarms and low amp hours remaining alarm value. Two auto-zero functions ( a one minute and/or a 24 hour measurement) are easily initiated from the front panel to zero the ammmeter for maximum long term accuracy.

The VAH60 draws only 0.018 amps and is designed to be left on continuously.

The VAH60 outputs Voltage (for all three battery banks), Amps and Amp-Hours Remaining on the standard NMEA 0183 serial data line. This information can be used to log performance or repeat the display information at a remote location on the CruzPro RP30 and/or RP110 data repeaters.
