Input selection and load planning
The two input bands are separate; the listing does not specify continuous operation across the gap between 130Vac and 190Vac. Use the 0–60A output range for continuous-load planning. The listed 66A peak pulse current is a separate parameter and should not be treated as a continuous output rating. Refer to the PDF for test and operating conditions.
