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 input
voltage (AC) is low or the DC voltage is higher
than shown in the chart.
