TDK Corporation announces the release of TDK-Lambda's new CUS250LD series low profile AC-DC power supplies. These single-output supplies provide 250-watts of output power with convection cooling (no fans required). This design eliminates the need for fan maintenance and reduces acoustic noise and vibrations. In addition, they feature a low profile of only 1.18" and a compact footprint of 4.0" x 7.8", making them an ideal choice for applications in light industrial, LED signage, communications, broadcast, gaming, point-of-sale, IT, and test & measurement equipment.

The supplies operate from a universal input of 85-264Vac, 47-63Hz, with PFC, enabling them to be used anywhere in the world. Moreover, they can operate from a 120-370Vdc input. These units have an input- to-output withstand voltage of 3kVac. The CUS250LD series are available with an output voltage of 3.3V, 4.2V, 5V, 12V, or 24Vdc, all of which have a +/-10% user-adjustment range.

The convection-cooled operating temperature range is from -25°C to +70°C with derating above +40°C. The power-saving efficiency is up to 90%. Other standard features include overvoltage and overcurrent protections plus a green LED indicator that is lit when the supply is on.

The CUS250LD series feature global ITE and general purpose safety agency certifications per UL/CSA/EN60950-1, EN50178, and are CE Marked. The supplies meet the conducted and radiated EMI requirements of EN55022-B & FCC Class B and include a three (3) year warranty.

More information about the CUS250LD is available at TDK-Lambda Americas' website: http://www.us.tdk-lambda.com/lp/products/cus-series.htm , or by calling 1-800-LAMBDA-4.
