CUS600M AC/DC Power Supplies

TDK Corporation CUS600M AC/DC power supply series in a 3” x 5” footprint from the TDK-Lambda brand is rated at 600 W. These compact products meet curve B conducted and radiated EMI in either a Class I or Class II (double insulated) construction, without the need for external filtering. This flexibility allows the CUS600M to be used in a wide range of applications, including home healthcare, medical, dental, test and measurement, broadcast, and industrial equipment.

The CUS600M series accepts an 85 V_AC to 264 V_AC input and has a no-load power consumption of less than 0.5 W when the output is inhibited. Seven output voltages are available, 12 V, 19 V, 24 V, 28 V, 32 V, 36 V, and 48 V. A 5 V 2 A standby voltage, remote on/off, remote sense, and a power good signal are fitted as standard. A cover with an integral fan option is also available. The open frame models measure 76.2 mm x 127 mm x 37 mm (W x L x H), or 85 mm x 157 mm x 42.5 mm with the cover/fan assembly fitted.

Convection cooled, the CUS600M can deliver 400 W (600 W peak) in -20°C to +40°C ambient temperatures, derating linearly to 200 W load at +70°C. With forced-air cooling or the integral fan fitted, the series provides 600 W at +55°C ambient, derating to 420 W at +70°C. The efficiency of the series is up to 96%, reducing internal power losses.

The CUS600M has an input to output isolation of 4,000 V_AC (2 x MoPP), an input to ground isolation of 2,000 V_AC (1 x MoPP) and an output to ground isolation of 1,500 V_AC (1 x MoPP) for suitability in B and BF rated medical equipment. The leakage current is <200 µA and the touch current is <100 µA. The maximum operating, transportation, and storage altitude is 5,000 m.

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, IEC60601-1-2 Edition 4 and IEC 61000-4 immunity standards.
