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.
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,
