Size (H x W x D): 2.5" x 2.5 " x 2.5," with a 2.25" Bezel Weight - Instrument: 9 oz. Weight - S-50 Shunt: 3 oz. Weight - S-300 Shunt: 12 oz. Power Requirements: 7.0 to 40 Volts, 2/10 Amp Display: Viewable in direct sunlight, with dimmable 12 and 24 volt backlight control lines. Accuracy: 1% of reading +/- one count. Resolution: VA-1A and VA-1A-XX (60 Amps and below for "XX") resolve amperage to .1 amps. VA-1A-XX (above 60 for "XX" ) resolve to 1 amps. All units resolve voltage to .1 volts. VA-1A Configuration: Contains an internal shunt for measuring current to 100 amps and voltage to 40 volts. VA-1A-XX Configuration: This unit must be matched to the aircraft's external shunt. The shunt value is determined by how many amps must pass through the external shunt in order to acheive a 50mV drop across the shunt leads (i.e., 100 amp, 50mV external shunt would be matched to a VA-1A-100, a 70 amp, 50mV external shunt would be matched to a VA-1A-70, etc...). |
