Lambda Completes Industrial Power Supply Lineup, Adding 300W and 600W Series with 5-Year Warranties

SAN DIEGO, CA (January 9, 2006) - Lambda has added a 300- and a 600-watt power supply series to complete the lineup for its successful HWS family; all models come with a five-year warranty. The new single-output HWS300 and HWS600 series are ideal for powering industrial equipment that demands very high reliability and long field-life.

Units are available in six nominal output voltages – 3.3, 5, 12, 15, 24 and 48 volts – and each model can be adjusted up to ±20% of its nominal voltage (-20/+10% for the 48V units) to accommodate non-standard system voltages. Additionally, a PV option can be specified on the 12 to 48-volt models, allowing the units to be remotely adjusted from 20% to 120% of nominal for 12- to 24-volt models, from 20% to 110% of nominal for 48-volt models.

The HWS300 and HWS600 series accept a wide range of input voltages – from 85VAC to 265VAC – and comply with both the SEMI F47 (208VAC) and EN61000-3-2 harmonic correction standards. Remote on/off, DC good and current-share signals are standard.

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 UL60950, CSA60950, EN60950, EN50178 specifications. They also meet EN61000-4-X immunity standards and are fully RoHS-compliant.

The HWS300 and HWS600 series are available now, priced from $365 each in single-unit quantities. More information can be found at Lambda’s Web site,
