Astrodyne Corporation adds 30-W units to its ECA Series of ultra-miniature encapsulated switching power supplies for EMC noise compliance to EN 60601-1-2:2001. The ECA30 series accepts universal input from 90 to 264 VAC and 22 models are available that provide output power of 30 W with single, dual and triple outputs from 5 to 48 VDC. They meet the power and EMC noise performance requirements in instrumentation, control and telecommunication systems while operating over an ambient temperature range from -10°C to 50°C without forced cooling or output power derating. All models contain internal input filtering, over-voltage and short circuit protection circuitry. For medical applications, the series is available in medically-approved EMA30 versions to UL/EN60601-1 safety levels.
