CruzPro V55: Digital voltage indicator

V55 Voltmetro CruzPro

Digital voltage indicator CruzPro V55, Voltmeter from 9.5 to 33 Vdc, high and low voltage alarm, NMEA 0183 output, backlit.


The CruzPro V55 is a voltmeter for reading boat battery voltage data from 9.5 to 33 VDC. The high and low voltage alarms are selectable independently and when the reading goes out of the set intervals the V55 will emit an alarm at 85 dB and the display will flash. For a better view of the screen, 5 levels of backlight can be selected and each setting will be saved in a non-volatile memory. Power supply 12/24 Vdc. Output NMEA 0183.

Calibrations are carried out 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.

Low/high voltage alarms can be set independently of each other and can be activated or deactivated at the touch of a button.
