SAN DIEGO, CA (Sept. 15, 2004) - Lambda has extended its SWS family of power supplies to include 300- and 600-watt models. The new SWS300 and SWS600 series are ideal for costsensitive applications that require both reliability and performance.sws group

Each series accepts a wide range of input voltages – from 85 to 265 VAC – and contains active PFC (power factor correction) circuitry to meet EN61000-3-2 standards. The units are available with 5-, 24- or 48-volt outputs and currents up to 120 amps.

Features include over-temperature, over-current and over-voltage protection; an output adjustment potentiometer (±10%); an integral power-good LED indicator; and screw terminals for input and output connections. The 600-watt models also have remote on/off, AC fail signal and current-sharing capabilities.

The high-power SWS supplies are cooled by an internal fan and deliver full power at 50oC without derating and up to 65oC with derating. The units measure a compact 2.05 x 4 x 7.8 inches (300-watt series) and 3.6 x 4.72 x 7.48 inches (600-watt series).

Both series meet Class B EMI standards (radiated and conducted); are safety approved to UL60950, CSA60950, EN60950, EN50178 specifications; and are CE marked. They also meet EN61000-4-X immunity standards.

The SWS300 and SWS600 series are available now, with prices starting at $125 in singleunit quantities. More information can be obtained at Lambda's Web site,
