S24SE/S24DE series 20W Single/Dual Output DC/DC Converter FEATURES Efficiency up to 88% Wide input range, 9V-36V Package with Industry Standard Pinout Package Dimension: 25.4 x25.4 x10.2mm (1.0 x1.0 x0.40)(No HSK) Over voltage protection, hiccup mode Over current protection, hiccup mode Positive or Negative Remote ON/OFF Without tantalum capacitor inside module Operating Temperature range - 40C to +85C Input to Output Isolation: 1600VDC RoHS Compliant 2 Years Product Warranty Heat-sink is option ND UL60950, 2 Edition, 2011-12-19 Recognized EN50155 compliance for Week 1618 datecode afterwards The S24SE/S24DE series is miniature, isolated 20W DC/DC converters with 1600VDC isolation. The S24SE/S24DE family comes with a host of industry-standard features, such as over current protection, over voltage protection, over temperature protection and remote on/off. An optional heatsink is available for more extreme thermal requirements. All models have an ultra-wide 4:1 input voltage range (9V to 36V). With operating temperature of -40C to +85C, it is suitable for customers critical applications, such as process control and automation, transportation, data communication and telecom equipment, test equipment, medical device and everywhere where space on the PCB is critical.
