AC/DC power supplies are designed for long-life LED signage

Convection and conduction cooled power supplies from TDK Lambda include 3.3, 4.2 and 28V models. The CUS200LD series of AC/DC power supplies are rated from 79 to 120W with convection cooling and 99 to 151W when mounted on an aluminium plate for conduction cooling. The series can deliver up to 206W for 10 seconds, says TDK. 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 supplies accept a wide range 85 to 265V AC input, and is now available with 3.3, 4.2, 5.0, 7.5, 12, 15, 24, 28 and 48V outputs. All models are adjustable over a ±10 per cent range to accommodate non-standard voltage requirements.

The CUS200LD is packaged in a compact low profile enclosure, measuring 160 x 60 x 31mm. All models will start up at -40 degrees C and can operate in ambient temperatures from -20 to +70 degrees C, derating from +45 degrees C (conduction cooling) to 40 per cent load at 70 degrees 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.

TDK is a leading electronics company based in Tokyo, Japan. It was established in 1935 to commercialise ferrite, a key material in electronic and magnetic products.
