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.

Of nominal output voltage. For trimming below
90% of nominal, a minimum load of 10% of
maximum rated power may be required.
