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.
