Lambda Introduces Dual Output Power Supplies With 200% Peak-Power Capability

SAN DIEGO, CA (Oct. 13, 2004) - Lambda has introduced a new family of dual-output power supplies that can deliver 200% of the nominal current rating for up to 10 seconds. The 5- and 24-volt ZWD series supplies are ideal for powering motors, solenoids and printers where 24-volt peak-current demand is needed for a short duration. zwd

The units are available with a 5-volt, 5-amp output for powering logic and auxiliary power circuits and a 24-volt output that can deliver a peak current of up to 18 amps. Remote on/off of just the 24-volt output is possible using a closed contact or jumper.

Cooled at 50°C, the ZWD100PAF can deliver continuous 100-watt convection and 196 watts peak, the ZWD150PAF yields 150-watt convection and 294 watts peak, and the ZWD225PAF delivers 225-watt convection with a peak of 440 watts.

All three basic models accept a wide range of input voltages – from 85 to 265 VAC – and contain active PFC (power factor correction) circuitry to meet EN61000-3-2 standards.

Three different mechanical configurations are offered – open frame, L bracket or fully enclosed – with the units measuring a compact 2.95 x 1.38 x 8.74 inches (ZWD100PAF), 3.35 x 1.57 x 8.74 inches (ZWD150PAF) and 3.74 x 1.77 x 8.74 inches (ZWD225PAF) in the openframe package. The supplies are available with Molex, JST or screw-terminal connections.

In addition to EN61000-3-2, the new power supplies meet EN61000-4-X immunity and Class B EMI standards. They are also safety approved to UL60950, CSA60950, EN60950 and EN50178 specifications and are CE marked.

The ZWD100PAF, ZWD150PAF and ZWD225PAF are available now, with prices starting at $94 in single-unit quantities. More information can be obtained at Lambda’s Web site,
