Lambda Intros HWS1500 Series Industrial Power Supplies

Lambda Electronics Inc. (San Diego, CA) introduced a new family of 1,500 W single-output power supplies with a five-year warranty, the HWS1500 Series, which is suitable for powering industrial equipment used in applications where long field-life demands high reliability. The units are available in four nominal output voltages of 12 V, 15 V, 24 V, and 48 V, and each model can be adjusted up to ±20 percent of its nominal voltage to accommodate non-standard system voltages. The 24 V model has a peak current capability of 105 A when operated with a line voltage of greater than 200 Vac.

The HWS1500 Series accepts a wide range of input voltages from 85 Vac to 265 Vac, and complies with both the SEMI F47 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 temperature. The units come in a compact footprint of 5 in x 3.25 in x 11 in, making them suitable for mounting in a 2U rack.

The new Lambda power supplies meet Class A EMI standards (radiated and conducted); are CE marked; and are safety-approved to UL60950, CSA60950, EN60950, and EN50178 specifications. The devices also meet EN61000-4-X immunity standards and will be RoHS-compliant beginning in January 2006. The HWS1500 Series will be available in November 2005, priced at $975 each in 50-unit quantities.
