NOTES
Refer to Appendix 1 for suggested input wiring
size, current ratings and circuit protection require-
ments.
6. Output Power
Continuously variable from 30 to 100 amps (±5%)
7. 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.
