TDK has announced 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
76.2mm x 127mm x 37mm (WxLxH), or 85mm x 157mm x 42.5mm with the cover/fan
Convection cooled the CUS600M can deliver 400W (600W
peak) in -20°C to +40°C ambient temperatures, derating linearly to 200W load at
+70oC. With forced air cooling or the integral fan fitted, the series provides
600W at +55°C ambient, derating to 420W 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 4,000Vac
(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 5,000 meters.
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
