NOTE
Refer to Appendix 1 for recommended input wir-
ing size, current ratings, and circuit protection re-
quirements.
Amperage depends on input voltage (Refer to Ap-
pendix 1).
4. Output Power
Master Power Supply:
Continuously adjustable by potentiometer from 50
to 150 amps
With Slave Power Supply:
Continuously adjustable by potentiometer from
100 to 300 amps
5. Duty Cycle (see NOTE)
NOTE
The duty cycle will be reduced if the primary in-
put voltage (AC) is low or the DC voltage is higher
than shown in the chart.
