New series of power supplies approved for use in medical markets

RS Components offers the availability of 11 new series of power supplies from TRACO Power that satisfies the demands of high-growth medical markets. These embedded switch-mode power supplies highlight a reinforced double I/O isolation system, according to the IEC/EN/ES 60601-1 third-edition medical safety standards, and includes 2 x MOPP (Means of Patient Protection) approval for operating altitudes up to 5000m. Furthermore, the units’ earth leakage current is less than 100µA, making them fitting for BF (body floating) class insulation applications. The units also work in compliance with the medical EMC emission and immunity levels, according to newest standard IEC60601-1-2 fourth edition, and risk management for medical devices, according to ISO14971. Key electrical features of the supplies comprise a broad range of voltage outputs – from 3.3VDC up to 48VDC for the 20W to 40W units, and from 12VDC up to 48VDC for the higher rated units; plus high power efficiencies extending up to a maximum of 91.5% for the 30W TPP 30-J series, for example, which also produces a high power density from a small-footprint package measuring only 1.5" x 3.95". Other features include: full load operating temperature range covering –40C to +60C with the ability to handle temperatures up to +85C with 50% load derating; universal AC input from 85VAC to 264VAC; enclosure options including open frame, encapsulated or metal enclosed packages, depending on the supply’s power rating; and a five-year warranty.
