Convection and conduction cooled power supplies

TDK Corporation announces the introduction of 3.3V, 4.2V and 28V output models to the TDK-Lambda brand CUS200LD series of AC-DC power supplies.

Rated from 79W to 120W with convection cooling and 99W to 151W when mounted on an aluminium plate for conduction cooling, the series can deliver up to 206W for 10 seconds.



The CUS200LD series conservative capacitor ratings are designed for long field life in LED signage applications, as well as industrial, broadcast, test, measurement and communication equipment.

The series accepts a wide range 85 to 265Vac input, and is now available with 3.3V, 4.2V, 5V, 7.5V, 12V, 15V, 24V, 28V and 48V outputs.

All models are adjustable over a ±10% range to accommodate non-standard voltage requirements. The CUS200LD is packaged in a compact low profile enclosure, measuring 160 x 60 x 31mm (L x W x H).

All models will start up at -40°C and can operate in ambient temperatures from -20 to +70°C, derating from +45°C (conduction cooling) to 40% load at 70°C.

Safety certification is to the IEC/EN/UL 60950-1 standards with CE marking for the Low Voltage, EMC and RoHS2 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 and IEC 61000-4 immunity standards.
