Highly inductive source impedances can affect the stability of the power module. In applications where power is supplied over long lines and output loading is high, it may be necessary to use a capacitor on the input to insure startup. By using a good quality low Equivalent Series Resistance (ESR < 1.0Ωat 100 kHz) capacitor of a 4.7µF for the 24V input devices and a 2.2µF for the 48V devices, capacitor mounted close to the power module helps ensure stability of the unit. Short Circuitry Protection Continuous, hiccup and auto-recovery mode. During short circuit, converter still shut down, The average current during this condition will be very low and the device will be safe in this condition. Thermal Consideration The converter is designed to operate in a variety of thermal environments and sufficient cooling must be provided to ensure reliable operation. Heat is removed by conduction from the pins to the PCB board, and by convection through airflow across the converter. Proper cooling can be verified by measuring the point as the figure below. The temperature at this location should not exceed 95°C. When operating, adequate cooling must be provided to maintain the test point temperature at or below 95°C. Although the maximum point temperature of the power module is 95°C, you can limit this temperature to a lower value for extremely high reliability.

Safety and Installation Instruction Fusing Consideration Caution: This power module is not internally fused. 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 safety agencies require a normal-blow fuse in 24Vin, 48Vin, 110Vin with maximum rating of 1000mA, 500mA, 300mA. Based on the information provided in this data sheet on Inrush energy and maximum dc input current; the same type of fuse with lower rating can be used. Refer to the fuse manufacturer’s data for further information.
