An input line fuse must always be used. This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of sophisticated power architecture. To maximize flexibility, internal fusing is not included; however to achieve maximum safety and system protection, always use an input line fuse. The input line fuse suggestions are below: Modules Fuse Rating Fuse Type 24Vin Nominal Models 3.15A Slow-Blow 48Vin Nominal Models 1.6A Slow-Blow 110Vin Nominal Models 1.A Slow-Blow This table is based on the information provided in this data sheet on inrush energy and maximum DC input current at low Vin. THERMAL CONSIDERATIONS 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, convection, and radiation to the surrounding environment. Proper cooling can be verified by measuring the point in the figure below. The temperature at this location should not exceed “maximum case temperature” When operating, adequate cooling must be provided to maintain the test point temperature at or below “maximum case temperature” You can limit this temperature to a lower value for extremely high reliability. ■ Thermal test condition with vertical direction by natural convection (20LFM).

This is accomplished by connecting an external resistor between the Trim pin and either the +Output or –Output pins. With an external resistor between the Trim and –Output pin, the output voltage set point increases. With an external resistor between the Trim and +Output pin, the output voltage set point decreases. The external Trim resistor needs to be at least 1/16W of rated power.
