CruzPro VAH30 Direct Current Analyzer

The VAH30 is a current analyzer for reading the data relating to the on-board battery. The instrument displays battery voltage and charge and discharge current. By applying Peukert's equation he is able to calculate the energy that has been consumed and the remaining energy. It is possible to set high and low voltage alarms and remaining hourly amps. When the alarm is activated, the instrument will emit an 85 dB sound and the display will flash.

Settings such as the backlight level and alarm values are saved in a non-volatile memory. The instrument is supplied with a 150 Amp SH-150 shunt for current measurement. All calibrations are carried out from the house, but the user can modify them as needed

Using the front panel it is also possible to modify the values for the battery voltage, current, charging efficiency, Peukert exponent, battery capacity in Ah, high and low voltage alarms and the minimum value of amperes per hour remaining. With the press of a button it will be possible to view the battery voltage (from 9.5 to 33.0 Vdc), charge and discharge current (from -150 to +150 Ampere) the remaining amperes per hour (from 0 to 3000 Ah) and the percentage of charge remaining in the battery (from 0 to 100%). The VAH30 also has a NMEA 0183 data output at 4800 bps for Voltage, Current and Hourly Ampere.
