VAH60
The VAH60 Digital Battery Monitor provides accurate low cost digital instrumentation for batteries between 9.5 and 33 Volts.
The VAH60 displays battery voltage and charging or discharge current and tells you how much battery capacity has been consumed and how much
is remaining. 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 VAH60 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 VAH60 comes complete with a calibrated 150 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 battery voltage (9.5 to 33.0 VDC), current being delivered to or draining from the battery (-150 to +150 Amps), the number of amp-hours remaining in the battery bank (0 to 3000 Amp-Hours) or the percentage charge remaining in the battery 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 VAH60 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.
The VAH60 outputs Voltage, Amps and Amp-Hours Remaining on the standard NMEA 0183 serial data line at
4800 BAUD.
This ASCII information can be used to log performance or repeat the display information at a remote location
on the matching CruzPro RP60, RP110 and MaxRp110 data repeaters (see www.cruzpro.com/rp60.html, www.cruzpro.com/rp110.html and www.cruzpro.com/maxrp110.html).
