Medical and industrial power supply series augmented with 500W models

October 22nd, 2021

TDK Corporation (TSE 6762) announces the introduction of the TDK-Lambda brand CUS500M1 AC-DC power supplies. The series is rated at 500W and is packaged in a 3 x 5” footprint. It provides an alternative for the 600W CUS600M models and an easy cost reduction for lower power, more cost sensitive applications. The CUS500M1 is suitable for use in a wide range of Class I or Class II (double insulated) applications, including home healthcare, medical, dental, test and measurement, broadcast and industrial equipment.

The CUS500M1 series accepts an 85 to 264Vac input and has a choice of seven output voltages: 12V, 19V, 24V, 28V, 32V, 36V and 48V. An integral fan option with cover is also 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 fitted.

Convection cooled the CUS500M1 can deliver 300W (500W peak) in -20°C to +40°C ambient temperatures, derating linearly to 150W load at +70°C. With forced air cooling or the integral fan fitted, the series provides up to 500W in a +60°C ambient, derating to 400W at +70°C. The efficiency of the series is up to 96%, reducing internal power losses.

The CUS500M1 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 the 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 and UKCA markings for the Low Voltage, EMC and RoHS Directives. The units also comply with EN 55011-B and EN 55032-B conducted and radiated emissions (for Class II applications, external filtering may be required), and meets the EN 61000-3-2 harmonics, IEC60601-1-2 Edition 4 and IEC 61000-4 immunity standards.
