(Note: The above current levels are based on the 30 minute duty cycle. To estimate the current draw on
the facility power at different duty cycles, multiply the above currents by the ratio of the output currents.
Ex.: An HC-75C will draw approximately 7.5 times the above current at the 1 second duty cycle.)
