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 untra-wide 4:1 input voltage range (9V to 36V).
With operating temperature of -40°C to +85°C, 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.
