POWER RATING (mounted horizontally with fins
vertical): 250 watts average (unidirectional) to 55°C
ambient temperature, derated linearly to 10% @ 125°C. 10
kilowatt peak (5 μsec pulse width; 1.25% duty cycle).
Maximum power rating into output port is 50 watts average.
Note: Model 45-3-XX is rated for 500 Watts average (uni-
directional) into the input and 250 Watts average
(maximum) into the output port.
