AC Main Output Current
The main AC current output is rated for 920 VA, with four different output
terminals continuously adjustable in the following ranges:
Output Current
Full Load Voltage
0 - 4 Amperes
230 Volts
0 - 10 Amperes
90 Volts
0 - 45 Amperes
20 Volts
0 - 115 Amperes
8 Volts
Output current is de-rated at output frequencies less than 50 Hz and greater than
120 Hz. For example, the available output current is less than 50 % of rated tap
value at 25 Hz, and less than 20 % at 16.6 Hz. Percentage varies depending on the
selected output tap, the test frequency and the load. For example, at the selected
output frequency of 180 Hz, you can get 110 Amperes at 7.7 Volts from the 115
Amp output tap, while at 300 Hz you get less than 95 Amperes at 6.7 Volts into the
same load. For more information contact the factory.
Output Current Duty Cycle
Maximum time on is 3 minutes followed by 20 minutes off. Duty is reduced to 1
minute on and 20 minutes off at ambient temperature of 122
°
F (50
°
C).
AC Voltage Output
The AC voltage output is independently controlled and may be phase shifted
relative to the Main AC Current/Voltage outputs.
