Electrical Characteristics

Electrical characteristics apply over the specified operating voltage range, output load and baseplate temperature, unless otherwise specified.

All temperatures refer to the operating temperature of the baseplate. Specifications apply for AC mains having no more than 5% total harmonic distortion.
