Electrical Specifications
These specifications are warranted over a temperature range of 0 °C to 50 °C
with local sense. Above 50 °C, derate output linearly to zero at 70 °C. Nominal
line voltages are 100/120/200/230/240 Vac. Specifications and characteristics
refer to a single output model unless otherwise stated, and specifications apply
to either front or rear outputs unless noted.
