VAF110

The VAF110 Digital AC Monitor provides accurate digital instrumentation for AC volts, amps, frequency and kW. The VAF110 displays ac voltage from 90 to 300 VAC RMS, AC current from 0 to 150 amps, AC frequency from 30 to 100 Hz and computes volt-amps (kW) from 0.0 to 45.0 kW. You can set Low and High voltage alarms, Low and High frequency alarms and a high kW alarm. When activated, the VAF110 built-in 85 dB alarm will sound and the display will flash. You can use the built-in generator cut-out output from the VAF110 to automatically shut down a faulty or out-of-condition generator or program the output terminal to send NMEA 0183 serial data at 4800 BAUD of AC Volts, Amps, Frequency and kW for remote monitoring of the data. Five levels of backlighting can be selected and all set-up, calibration constants and alarm values are saved to non-volatile memory. The VAF110 comes complete with both voltage and current transformers to measure ac volts and ac current.

All constants and calibrations are pre-set during manufacture but you may alter these settings to suit your particular needs. Calibrations can be altered using the front-panel switches for: AC voltage, AC current, AC frequency, low and high voltage alarms and low and high frequency alarms.

With a press of the button you can display volts, amps, frequency or kW.

High volts, Low volts, High and Low frequency and high kW alarms can be independently set using the front panel switches and all alarms can be turned ON/OFF simultaneously with the press of a single key.

The VAF110 draws only 0.037 amps can be powered from any 9.5 to 33.0 VDC power source. 5 levels of backlight (including OFF) can be selected from the front panel and is saved to non-volatile memory.

The VAF110 outputs standard NMEA 0183 serial data.

This ASCII information can be used to log performance or repeat the display information at a remote location on the CruzPro RP30 and/or RP110 data repeaters (see www.cruzpro.com/rp30.html and www.cruzpro.com/rp110.html). If NMEA 0183 serial data is not required, then the output terminal can be programmed as an external alarm output pin or generator cut-out control.
