TDK Corporation has introduced the KMS-A series of single output, medically certified 15W-60W encapsulated power supplies. With a Class II input, the products require no earth ground connection, making them ideal for use in a range of medical, dental and home healthcare. They are also suitable for broadcast, test and measurement, and industrial equipment applications.

Comprising of three power levels, 15W, 30W and 60W, the series is available in 5V, 9V, 12V, 15V and 24V output voltages. Off-load power draw is <0.1W for the KMS15A and KMS30A and <0.3W for the KMS60A with product efficiencies as high as 89%. All models can operate from a wide range input voltage of 90-264Vac.

The power supplies are suitable for board-mounting and are enclosed in UL 94V-0 rated resin cases. The 15W measures 52.5mm x 27.5mm x 23.5mm, the 30W 64mm x 45mm x 23.5mm, and the 60W 89mm x 63.5mm x 27mm. The products can operate convection cooled in ambient temperatures of -40C to +85C, with appropriate derating above 50C, and have a maximum operating altitude of 5,000m.

The series has been certified to UL/CSA/IEC/EN 60950-1, ANSI/AAMI ES60601-1, IEC/EN 60601-1 and carries the CE mark for the Low Voltage and RoHS2 Directives. TDK-Lambda’s medical safety compliance extends to providing 4kVac, 2 x MOPPs (Means of Patient Protection) input to output isolation and a touch current of <100µA at 264Vac. All models comply with EN 55011-B (conducted and radiated) emissions and EN 61000-4-2 immunity standards.
