CruzPro VAH65 Digital Volts Amp Three Battery Banks provides accurate low cost digital instrumentation for three banks of batteries between 9.5 and 33 Volts.
The VAH-65 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 efficiency factors. You can set Low and High voltage alarms and Low Amp-Hours Remaining alarms.
When activated, the VAH65 built-in 85 dB alarm will sound and the display will flash. Five levels of backlighting can be selected and all set-up, calibration constants and alarm values are saved to non-volatile memory. The VAH-65 comes complete with a calibrated 450 Amp shunt to measure current.
All constants and calibrations are pre-set during manufacture but you may alter these settings to suit your particular needs. Calibrations can be altered using the front-panel switches for: Battery voltage, 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. An auto-zero function is easily initiated from the front panel to zero the ammmeter.
With a press of the button you can display three different battery voltages (9.5 to 33.0 VDC each), current being delivered to or draining from the main house bank (-450 to +450 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%).
High volts, Low volts and Low Amp-Hours Remaining alarms can be independently set using the front panel switches and all alarms can be turned ON/OFF simultaneously with the press of a single key.
The VAH65 Digital Volts Amp draws only 0.017 amps and is designed to be left on continuously. 5 levels of backlight (including OFF) can be selected from the front panel and is saved to non-volatile memory.
