The S24SE/S24DE family, the highest power density (30W), supplies industrial 1”X1” isolated power converter whose pinout follows
industry standard. The S24SE/S24DE series 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 -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.
