Lambda's 300W and 600W Power Supplies Deliver 300% Peak Power

SAN DIEGO, CA (June 24, 2008) - Lambda's new series of 300W and 600W power supplies deliver up to 300% peak output power. The AC-DC single-output HWS300P and HWS600P series are ideal for powering industrial equipment that demands high peak currents (e.g., motors, pumps), ultra-reliability, and extended field-life. All HWS series supplies come with Lambda Americas' exclusive Limited-Lifetime-Warranty.hws-p

Units are available in three nominal output voltages; including 24, 36 and 48 volts, and each model can be adjusted up to +10%/-20% of its nominal voltage to accommodate non-standard system voltages. The HWS300P and HWS600P series accept a wide range of input voltages – from 85VAC to 265VAC – and comply with the SEMI F47 (with 200VAC line or higher), which is required in the semiconductor fabrication industry, plus EN61000-3-2 harmonic and power factor correction standards. Remote on/off and DC good signals, and overvoltage/overcurrent protections, are standard. A current-share signal for paralleling two units is standard on the 600-watt models.

The power supplies have a high-quality internal fan and can be operated in a -10°C to +70°C ambient. The 300- and 600-watt units come in a compact footprint – respectively 2.4 x 3.23 x 6.5 and 3.94 x 3.23 x 6.5 inches – making them suitable for mounting in a 2U rack.

The new Lambda power supplies meet Class B EMI standards (radiated and conducted), are CE marked, and are safety-approved to UL/CSA/EN60950-1 and EN50178 specifications. They also meet EN61000-4-X immunity standards and are fully RoHS-compliant.

The HWS300P and HWS600P series are available now, priced from $214.00 each in 100 unit quantities. More information can be found at Lambda's web site:
