VAH110 CruzPro: Direct Current Analyzer

VAH110 Analizzatore Corrente CruzPro

On-board battery voltage and current indicator, CruzPro VAH110, voltage reading, charge and discharge current, Ah consumed and residual.


The VAH110 is a direct current analyzer for reading boat battery data with the ability to monitor up to 3 battery packs. The instrument displays the voltage of each battery and the charging and discharging current. By applying Peukert's equation he can calculate the energy that has been consumed and the remaining energy. It is possible to set high and low voltage alarms and remaining amperes per hour. When the alarm is triggered by readings other than those set, the instrument will sound at 85 dB and the display will flash.

The selection of 5 levels of backlighting allows a correct vision in the dark. All settings, calibrations and alarm values are stored in a non-volatile memory. The instrument comes with a 450 Ampere SH-450 shunt for current measurement. All calibrations are performed 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 alarms of battery voltage, current, charge efficiency, Peukert exponent, battery capacity in Ah, high and low voltage alarms and minimum value of Amperes per hour remaining. At the touch of a button it is possible to display the battery voltage (from 9.5 to 33.0 Vdc), charging and discharging current (from -450 to +450 Ampere), the remaining Amperes (from 0 to 3000 Ah) and the percentage of charge remaining in the battery (from 0 to 100%). The VAH110 has output Nmea 0183 at 4800 bps for voltage, current and Ampere Hours.

Highly reliable, wide-screen, clear motorboat instrument series for easy reading of data from a distance. They are equipped with NMEA 0183 output so that the detected information can also be transmitted to other instruments or systems.
The construction is elegant and suitable to better decorate the consoles of the boats.
The instruments are all 110 x 110 mm in size, require a 54 mm diameter recessed hole, "non-volatile" memory and five levels of backlighting.
