With three currents in parallel:
Output Current
Power Max V
12 Amperes 600 VA 50 Vrms
22.5Amperes 600 VA 26.7 Vrms
45 Amperes 600 VA 13.4 Vrms
With four currents in parallel:
Output Current
Power Max V
16 Amperes 800 VA 50 Vrms
30 Amperes 800 VA 26.7 Vrms

Battery Simulator
The battery simulator provides the following DC output:
24, 48, 125 or 250 Volts at 60 Watts. Voltage output is controlled
via the Touch-View Interface, or through AVTS software.
Metering
Measured output quantities such as AC Amperes, AC Volts, DC
Volts or DC Amperes, and Time may be simultaneously displayed
on the large, variable contrast, color LCD touch screen. The
memory feature of the metering provides fast and accurate preset
of test values. The AC and DC outputs display the approximate
voltage/current output prior to initiation of the outputs. This
provides a fast, easy method for preset of outputs. Other values
that may be displayed, depending on which test screen is in view,
are phase angle, frequency, Ohms, Watts, VARS and Power Factor.
All Accuracies stated are from 10 to 100% of the range at 50/60 Hz.
