Electrical Characteristics
Electrical characteristics apply at the nominal value of input voltage, 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.
