TDK-Lambda launched its 200W models of it LS Series of convection cooled power supplies. The new LS200 Series feature a universal input range of 88 to 264Vac (no select switch), with an input surge rating of 300VAC 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 48Vdc. 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 200W of output power. The open-frame U-channel version is rated at 150W with convection cooling, and up to 200W 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 1.5kVac input to ground, 3kVac input to output, and 500VDC 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.
In many applications, the ac input line-quality is poor and factory equipment can cause input voltages to fluctuate and generate high voltage spikes. Such line transients and disturbances can drastically reduce the life of many low-cost power supplies that are only designed for use in office environments. "TDK-Lambda’s LS Series offers a new solution for these applications," said David Norton, VP of Marketing for TDK-Lambda Americas. "At a low cost this series still retains the specifications needed for many industrial, automation and test & measurement applications."
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.
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". These units are available now and priced at $38.50 each in 1000 piece quantities.
