ELECTRICAL CHARACTERISTICS
Electrical characteristics apply over the full operating range of input voltage, output power 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.
