The CruzPro V55 is a voltmeter for reading vessel battery voltage data from 9.5 to 33 Vdc. The high and low voltage alarms are independently selectable and when the reading goes out of the set ranges the V55 will sound an 85 dB alarm and the display will flash. For a better view of the screen, 5 levels of backlighting are selectable and each setting will be saved in a non-volatile memory. 12/24 Vdc power supply. NMEA 0183 output.
Calibrations are made by the manufacturer, but can be varied for any particular use. Calibrations such as battery voltage and low / high voltage alarm can be changed from the front panel.
The low / high voltage alarms can be set independently of each other and can be activated or deactivated by pressing a button.
