Medical and industrial power supplies offer efficiencies up to 96%

TDK Corporation has introduced the 600W rated TDK-Lambda brand CUS600M series of AC/DC power supplies. With efficiencies of up to 96%, internal heating is minimised, enabling reliable operation in the industry-standard 3” x 5” footprint. The series is certified to the medical and ITE standards for Class I and II operation. Targeted applications include medical, home healthcare, dental, test and measurement, broadcast, professional audio and industrial equipment.

A selection of seven standard output voltages is available: 12V, 19V, 24V, 28V, 32V, 36V and 48V. All models accept an 85 to 264VAC input and have a no-load power consumption lower than 0.5W when the output is inhibited. A 5V 2A standby voltage, remote on/off, remote sense and a power good signal are installed as standard. A cover with integral fan option is possible. The open frame models measure 76.2mm x 127mm x 37mm (WxLxH), or 85mm x 157mm x 42.5mm with the cover/fan assembly.

Convection cooled, the device can produce 400W (600W peak) in -20C to +40C ambient temperatures, derating linearly to 200W load at +70C. With forced-air cooling the series provides 600W at +55C ambient, derating to 420W at +70C.

Safety certifications include IEC/EN/ES 60601‑1 and IEC/EN/UL 62368‑1 with CE marking for the Low Voltage, EMC and RoHS Directives. The units also comply with EN 55011‑B, and EN 55032‑B conducted and radiated emissions (Class I and II), and meet the EN 61000‑3‑2 harmonics, IEC 60601‑1‑2 Edition 4 and IEC 61000‑4 immunity standards.
