An external fuse must always be employed! To meet international safety requirements, an input line fuse should be used. Input wires and copper coil must be capable of conducting a current of 1.5 times the value of the fuse. If one of the input lines is connected to chassis ground, then the fuse must be placed in the other input line. A fuse with ratings of 20A is recommended for APA04 non-isolated boost series. Safety Considerations For safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e., UL1950, CSA C22.2 No. 950-95, and VDE 0805 (EN60950, IEC950). For the module's output to be considered meeting the requirements of safety extra-low voltage (SELV), one of the following must be true: 1 All inputs are SELV and floating, with the output also floating. 2 All inputs are SELV and grounded, with the output also grounded. 3 Any non-SELV input must be provided with reinforced from any other hazardous voltages, including the ac mains, and must have a SELV reliability test performed on it in combination with the converters. Inputs must meet SELV requirements. If the input meets extra-low voltage (ELV) requirements, then the converter's output is considered ELV.

APA04 Mechanical Considerations Thermal Performance APA04 non-isolated module can work properly under natural convection in ambient temperature up to 30°C. If air-flow is applied, it can work in a much wider temperature range( See derating curves for reference ). In order to maintain efficient heat dissipation, the converters should be mounted parallel with the air-flow direction. Soldering APA04 non-isolated converter is compatible with standard wave soldering techniques. When wave soldering, the converter pins should be preheated for 20-30 seconds at 110° C, and wave soldered at 260°C for less than 10 seconds. When hand soldering, the iron temperature should be maintained at 425°C and applied to the converter pins for less than 5 seconds. Longer exposure can cause internal damage to the converter. Cleaning can be performed with cleaning solvent IPA or with water. Mechanical Chart On the next page. Recommended Hole Pattern Dimensions are in millimeters Component-side footprint.
