Power supplies feature convection cooling

Following the launch of its LS Series of low cost, convection-cooled power supplies rated from 25 to 150 watts, TDK-Lambda now announces its 200-watt models. The new LS200 Series feature a universal input range of 88 to 264 Vac (no select switch), with an input surge rating of 300 Vac for five seconds, and is available in either an enclosed fan-cooled version or in an open-frame U-channel configuration.

Developed to provide low cost and small size power solutions, the LS200 Series of ac-dc single-output power supplies are available now with the most popular dc output voltages, including 3.3, 5, 7.5, 12, 15, 24, 36, and 48 Vdc. All dc outputs are adjustable up to +/- 10% via a front panel-mounted adjustment potentiometer. In addition, a front panel green LED is “On” when the output is good and remote On/Off control is standard.

With its internal fan-cooling, the LS200 Series will provide up to 200 W of output power. The open-frame U-channel version is rated at 150 W with convection cooling, and up to 200 W with user provided air-flow. These power supplies not only carry the CE Mark but are certified to UL, CSA, and IEC 60950-1 safety specifications. The units have a withstand voltage of up to 1.5 kVAC input to ground, 3 kVAC input to output, and 500 Vdc output to ground. This series conforms to the immunity standards of EN61000-4-X and the EMC/EMI standards of EN55011-B, EN55022-B, and FCC-Class B.

All models meet the Power Factor and Harmonic Correction requirements of EN61000-3-2 and are RoHS compliant. Also included are overcurrent and overvoltage protection circuits, and all units carry a three year warranty. The operating temperature range is from -25° to 70° C with deratings above 50° C. The LS200 Series measure 7.8 x 3.9 x 1.61 in.
