TDK Power - 600W Class I & II in 3x5 Footprint

March 2, 2020

TDK Corporation (TSE 6762) announces the introduction of the TDK-Lambda brand CUS600M AC-DC power supply series in a 3 x 5” footprint.  Rated at 600W 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 to 264Vac input and has a no-load power consumption of less than 0.5W when the output is inhibited.  Seven output voltages are available, 12V, 19V, 24V, 28V, 32V, 36V and 48V.  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 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 CUS600M can deliver 400W (600W peak) in -20oC to +40oC ambient temperatures, derating linearly to 200W load at +70oC. With forced air cooling or the integral fan fitted, the series provides 600W at +55oC ambient, derating to 420W at +70oC.  The efficiency of the series is up to 96%, reducing internal power losses.
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 (Class I and II), and meet the EN 61000-3-2 harmonics, IEC 60601-1-2 Edition 4 and IEC 61000-4 immunity standards
