TDK-Lambda unveils energy saving 150W medical power supplies

According to the power supplies specialist, the single output CSS150 combines a 4kVac reinforced input to output isolation with dual fusing and an input to ground isolation of 1.5kVac, to meet global 60601-1 2nd & 3rd Editions safety approvals for medical equipment. The CSS150 is suitable for a range of medical and dental equipment, as well as high integrity applications such as ATE, automation, broadcast, instrumentation, routers, servers and security networks. The CSS150 range covers all commonly used output voltages from 12 to 48V with 89% typical efficiency, and meets ErP and Climate Savers Eco-Design guidelines with less than 0.5W no load power consumption. Other features include remote ON/OFF, and overcurrent and overvoltage protection circuitry. Offered in a 3 x 5in footprint, with a low profile height of 33mm including underside components, the open frame CSS150 power supply is designed to deliver up to 100W at 50°C under convection cooling and 150W at 50°C in forced air. TDK-Lambda says worst case leakage current is less than 250µA at 264Vac/60Hz, complying with worldwide medical equipment requirements. All models in the range meet conducted and radiated emc requirements of EN55011-B and FCC Class B (without additional filtering or components) and EN60601-1-2 immunity specifications. In addition, the CSS150 carries the CE mark, according to the LV Directive, and comes with a two year warranty.
