30W wall plug adaptors offer 45W peak & 0.2W no-load

Although referred to as a 30W unit, nominal power is 36W and peak power an impressive 45W (considerably more for very short periods). Built in intelligent over temperature protection adds to both expected life and operation reliability. The uniquely low no load input power of less than 0.2W is another contributor to reduced energy consumption and reduced stress over time.

The EXM30 offers low energy losses, long life expectancy, reliability in-use, and overload resilience, potentially leading to considerable savings over time. By removing space requirement, heat generation and EMC emission, as well as some regulatory and certification requirements from the application, wall plug adaptors significantly reduce both development time and cost for the application, compared to using built in power supplies.

“When designing the EXM30 series we aimed high,” said Martin Fredmark, Vice President of Product Management, Powerbox. “The low leakage current requirements for type CF and critical care applications, the water ingress protection requirements of critical medical facility and home care applications, very high ambition for life expectancy, power losses, high peak power, etc., and a desire to have one standard unit for global use, were all on the list. Less than 10µA leakage current, IP 21 protection, Homecare 60601-1-11 approval, 88% efficiency, 440,000h MTBF, 85-264VAC input voltage, and a design with interchangeable AC plugs shows that we succeeded.”

The EXM30 series meets electrical safety IEC60601-1 Edition 3, IEC60601-1-11, class II isolation, IP21 protection, as well as environmental RoHS, REACH and WEEE.
