Thermal Consideration
The power module operates in a variety of thermal environments. However, sufficient cooling should be
provided to help ensure reliable operation of the unit. Heat is removed by conduction, convention, and radiation
to the surrounding environment. Proper cooling can be verified by measuring the point as the figure below. The
temperature at this location should not exceed 105°C. When operating, adequate cooling must be provided to
maintain the test point temperature at or below 105°C. Although the maximum point temperature of the power
modules is 105°C, you can limit this temperature to a lower value for extremely high reliability.

Remote ON/OFF Control
The positive logic remote ON/OFF control circuit is included.
Turns the module ON during a logic High on the On/Off pin and turns OFF during a logic Low. The On/Off pin
is an open collector/drain logic input signal (Von/off) that’s referenced to GND. If not using the Remote On/Off
feature, please open circuit between on/off pin and –input pin to turn the module on.
