A very high efficiency allows an operating temperature range of –40°C to +85°C. A built-in EMI input filter complies with EN 55022, class A with external components. Further standard features include remote On/Off and short-circuit protection. Typical applications for these converters are battery operated equipment, instrumentation, communication and industrial electronics, everywhere where isolated,tightly regulated voltages are required and space is limited on the PCB.
