Electrical Characteristics
Electrical characteristics apply over the full operating range of input voltage, output load (resistive) and baseplate temperature,
unless otherwise specified. All temperatures refer to the operating temperature at the center of the baseplate. Specifications apply
for AC mains having up to 5% total harmonic distortion.
