Lambda Launches Low Cost 50W to 150W Enclosed Power Supplies

SAN DIEGO, CA (August 5, 2008) - Lambda has launched four new series of power supplies. Developed to provide low cost and small size, the LS50 (50W) through LS150 (150W) series of AC-DC single-output power supplies cover the popular output voltages including 3.3V, 5V, 12V, 15V, 24V, 36V and 48V. ls

In many applications, the AC input line-quality is poor and factory equipment can cause the input voltages to fluctuate and generate high voltage spikes. Such line transients and disturbances can drastically reduce the life of many power supplies that are only designed for use in an office environment.

"Lambda's LS series of power supplies offers a new solution for these applications," says David Norton, VP of Marketing for Lambda Americas. "At a low cost, this series still retains the specifications needed for automation and test & measurement applications."

Available in four power ratings, 50W, 75W, 100W, and 150W, the enclosed units not only carry the CE Mark but meet UL/EN/IEC60950-1 safety agency specs. The units have a withstand voltage of up to 1.5kVAC input to ground, 3kVAC input to output, and 500VDC output to ground. The series also conform 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. Other features include a voltage adjustment potentiometer, a Green LED “On" indicator and screw terminal connections. All units carry a three year warranty.

The convection-cooled operating temperature range is from -25°C up to +70°C with deratings above 50°C. The LS50 through LS100 series can operate with a universal AC input of 88 to 264VAC, and the LS150 has a 115/230VAC selector switch. The supplies range in size from 3.9" x 3.8" x 1.4" up to 7.8" x 3.9" x 1.5" and are available now with prices starting from $18.44 each in 100 unit quantities.
