600W Class I and Class II 3”x 5” medical and industrial power supplies offer efficiencies up to 96%
Posted : 02 Mar 2020
TDK Corporation (TSE 6762) announces the introduction of the 600W rated TDK-Lambda brand CUS600M series of AC-DC power supplies. With efficiencies of up to 96% internal heating is minimised, allowing reliable operation in the industry standard 3” x 5” footprint. The series is certified to the medical and ITE (Information Technology Equipment) standards for Class I and II (no earth ground connection) operation. Target applications include medical, home healthcare, dental, test and measurement, broadcast, professional audio and industrial equipment.
A choice 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 of less than 0.5W, when the output is inhibited. A 5V 2A standby voltage, remote on/off, remote sense and a power good signal are fitted as standard. A cover with integral fan option is available. The open frame models measure 76.2 x 127 x 37mm (WxLxH), or 85 x 157 x 42.5mm with the cover/fan assembly.
Convection cooled, the CUS600M can deliver 400W (600W peak) in -20°C to +40°C ambient temperatures, derating linearly to 200W load at +70°C. With forced air cooling the series provides 600W at +55°C ambient, derating to 420W at +70°C.
The CUS600M has an input to output isolation of 4,000Vac (2 x MoPP), an input to ground isolation of 2,000Vac (1 x MoPP) and an output to ground isolation of 1,500Vac (1 x MoPP) for suitability in B and BF rated medical equipment. The leakage current is <200µA and touch current is <100µA. The maximum operating, transportation and storage altitude is 5,000m.
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, and meet the EN 61000‑3‑2 harmonics, IEC 60601‑1‑2 Edition 4 and IEC 61000‑4 immunity standards.
