CruzPro VAF30: Alternating Current Analyzer

VAF30 Analizzatore Corrente CruzPro

CruzPro VAF30 alternating current analyzer, voltage and current at the dock or from the generator, NMEA 0183 output, high and low voltage alarm.


The VAF30 is a current analyzer for reading quayside or generator current data such as Volts (90 to 300 VRMS), Amps (0-150 A), frequency (40-70 Hz) and kW (0-45 kW). It is possible to select both a high and low voltage alarm and a high and low frequency alarm. When the alarm is activated the instrument will sound an alarm at 85 dB while the display will flash.

It is possible to use the external output to automatically switch off the generator or to send NMEA 0183 data at 4800 bps for voltage, absorption, frequency and power consumption. 5 levels of backlight can be selected and all settings are saved in a permanent memory. It comes with both transformers for reading current and voltage.

All calibrations are carried out from the parent company but the user can modify them according to his needs. The alarm values for voltage, current and frequency can also be changed from the front panel. You can view the various readings on the screen at the touch of a button.
