Board-mount, AC/DC power supplies with medical and ITE certifications

Stocked by Digi-Key, the TDK Corporation has introduced the TDK-Lambda KMS-A series, 15W to 6 W, board-mount, AC/DC, medical- and ITE-certified power supplies. Capable of starting up at -40C, the convection cooled units will operate in ambient temperatures of up to 80C and are rated for full load over a -30°C to 50°C range. The series is designed for use in a wide range of medical and industrial applications including dental, home healthcare, and test and measurement. The encapsulated series is comprised of three power levels: 15W, 30W, and 60W and five output voltages: 5V, 9V, 12V, 15V, and 24V. The 15W models measure 52.5mm x 27.5mm x 23.5mm, the 30W models measure 64mm x 45mm x 23.5mm, and the 60W models measure 89mm x 63.5mm x 27mm. Rated for Class II operation, the KMS-A series requires no earth-ground connection. The series accepts an input voltage of 90VAC to 264VAC and requires no external input filtering components. Efficiencies are up to 89% and have an off-load power draw of less than 0.1W for the KMS15A, less than 0.15W for the KMS30A and less than 0.3W for the KMS60A. All units meet EN55011-B conducted and radiated emissions and IEC 61000-6-2 and IEC 61000-4 immunity standards.
