TDK-Lambda – Energy-saving 150W medical power supplies (TDK Lambda AC-DC medical power supply)

A new 150W PSU range has been introduced by TDK-Lambda, expanding its CSS series of AC-DC medical power supplies. 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 well-suited to medical and dental equipment and other high-integrity applications including 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 over-current and over-voltage protection circuitry. Offered in an industry-standard 3 x 5-inch footprint, with a low-profile of 33mm including underside components, the open-frame CSS150 power supply can deliver up to 100W at 50C under convection cooling and 150W at 50C in forced air. Worst-case leakage current is less than 250µA at 264Vac/60Hz, complying with worldwide medical equipment requirements.

All models meet conducted and radiated EMC requirements of EN55011-B and FCC Class B (without additional filtering or components) and EN60601-1-2 immunity specifications for greater reliability. In addition, the CSS150 carries the CE mark, according to the LV Directive, says the company.
