Quiet 800W and 1000W medical and industrial power supplies offer power densities up to 27.2W per cubic inch

TDK Corporation (TSE 6762) introduces the TDK-Lambda series CUS800M and CUS1000M AC-DC power supplies in a 171 x 85 x 42.5 mm (6.73 x 3.35 x 1.67 in) housing. These very compact products have a nominal power of 800 W and 1000 W and are equipped with an adjustable speed fan, which produces 30 to 42 dBA of noise. The power supplies can be used in a wide range of applications, including medical, dental, test and measurement, transmitting and industrial equipment.

The power supplies have an input voltage range of 85 to 265 VAC, deliver full power at 90 VAC and are available with 12 V, 24 V, 36 V or 48 V output. They are equipped as standard with 5 V/2 A standby voltage, remote on/off, remote sense and a power good signal. With efficiencies up to 95.5%, less internal heat is generated, which benefits reliable operation in the compact housing. No-load power consumption is typically <0.6 W when the power supply is in standby. These CUS-M versions can operate at ambient temperatures from -20 °C to +70 °C, with linear derating up to 60% of the load at +70 °C from 40 °C. Both models have a five-year warranty.

The CUS800M and CUS1000M have an insulation voltage between input and output of 4,000 VAC (2 x MoPP); between input and earth this is 2,000 VAC (1 x MoPP) and between output and earth 1,500 VAC (1 x MoPP). This makes the power supplies suitable for B and BF classified medical equipment. The leakage current is <250 µA and the maximum operating, transport and storage altitude is 5,000m.

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 power supplies also comply with EN 55011-B and EN 55032-B standards for conducted and radiated emissions, as well as EN 61000-3-2 for harmonics, IEC60601-1-2 Edition 4 and IEC 61000-4 standards in the field of immunity.
