TECHNICAL DATASHEET WALL INDUSTRIES, INC. Rev. E RA4805UW5 (888) 597-WALL www.wallindustries.com Page 4 of 10 DESIGN CONSIDERATIONS Under Voltage Lock Out (UVLO) The converter output is disabled until the input voltage exceeds the UVLO turn-on limit. The converter will remain ON until the input voltage falls below the UVLO turn-off limit. Over Current Protection The converter is protected from short circuit and over current conditions. Upon sensing an over current, the output will begin to drop (or ‘foldback’) limiting the output power. Further increasing the output current will cause the converter to shut off and then restart (or ‘hiccup’) until the over current condition is removed. Shorting the output will cause the converter to immediately enter the ‘hiccup’mode. Over Temperature Protection The converter is NOT protected from over temperature conditions. Exceeding the rated case temperature of 100°C may cause permanent damage to the unit. Input Filter No additional input capacitor is needed for the power supply to operate. However, to reduce input ripple and high frequency noise, it is highly recommended that a minimum 1 µF/100 V ceramic capacitor be added across the input pins. Output Filter No additional output capacitor is needed for the power supply to operate. However, to reduce high frequency noise, a 1µF/10V ceramic capacitor is recommended. Fusing For applications that are required to meet UL and/or CSA safety regulations, the input to the converter shall be current limited or supplied through a 2 A fuse. This unit is designed to meet these regulations, but is not certified. Final Electrical Test See Appendix I for description of Final Electrical Test. All units tested 100% at 25°C.
