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 maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The input line fuse suggest as below: Model Fuse Rating (A) Fuse Type PMR20-24S W, PMR20-24D W 4 Slow-Blow PMR20-48S W, PMR20-48D W 2 Slow-Blow PMR20-110S W, PMR20-110D W 1 Slow-Blow The table based on the information provided in this data sheet on inrush energy and maximum DC input current at low Vin.

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 as the figure below. The temperature at this location should not exceed 105ºC. When Operating, adequate cooling must be provided to maintain the test point temperature at or below 105ºC. Although the maximum point Temperature of the power modules is 105ºC, you can limit this Temperature to a lower value for extremely high reliability. Thermal test condition with vertical direction by natural convection (20LFM). TOP VIEW

5 Output Voltage Adjustment Output voltage set point adjustment allows the user to increase or decrease the output voltage set point of the module. This is accomplished by connecting an external resistor between the Trim pin and either the +Vout or -Vout pins. With an external resistor between the Trim and -Vout, the output voltage set point increases. With an external resistor between the Trim and +Vout, the output voltage set point decreases. The external Trim resistor needs to be at least 1/16W of rated power.
