CUS800M/CUS1000M Series Power Supplies

TDK-Lambda's CUS800M and CUS1000M AC-DC power supply series have a very compact 6.73" x 3.35" x 1.67" (171 mm x 85 mm x 42.5 mm) case size. Rated at up to 800 W and 1000 W, these products also feature a variable speed fan with typically 30 dBA to 42 dBA audible noise. The power supplies can be used in a wide range of applications, including medical, dental, test and measurement, broadcast, and industrial equipment.

The series accepts an 85 V_AC to 265 V_AC input, delivering full power at 90 V_AC, and is available with 12 V, 24 V, 36 V, and 48 V outputs. A 5 V 2 A standby voltage, remote on/off, remote sense, and a power good signal are fitted as standard. With efficiencies of up to 95.5%, internal heating is reduced, allowing reliable operation in the compact package size. The off-load power consumption is typically <0.6 W when the supply is put into standby mode. These CUS-M models can operate in -20°C to +70°C ambient temperatures, derating linearly from +40°C to 60% load at +70°C. Both models have a five-year warranty.

The CUS800M and CUS1000M have an input-to-output isolation of 4000 V_AC (2 x MoPP), an input-to-ground isolation of 2000 V_AC (1 x MoPP), and an output-to-ground isolation of 1500 V_AC (1 x MoPP) for B and BF rated medical equipment. The leakage current is <250 µA, and the maximum operating, transportation, and storage altitude is 5000 m.

Safety certifications include IEC/EN/ES 60601-1 and IEC/EN/UL 62368-1 with CE/UKCA 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, IEC60601-1-2 Edition 4, and IEC 61000-4 immunity standards.
