Lambda Introduces Single-, Dual- and Triple-Output Power Supplies with Industry-Standard 2- x 4-inch Footprint

SAN DIEGO, CA (August 19, 2005) - Lambda has announced a new family of power supplies in the industry-standard 2- x 4-inch format. Called the ZP series, the power supplies are ideal for use in a wide variety of applications, such as data communications, LED signage, point-ofsale displays, and test-and-measurement equipment.

zp seriesUnits are available in three different output configurations. A 20- to 60-watt single-output version includes all the popular voltages from 3.3 to 48 volts, and 30- to 50-watt dual- and tripleoutput versions provide a choice of output combinations and polarities. Typical efficiency for the 48-volt models is 88%. All three configurations accept a broad range of input voltages: 90 to 264VAC, 47 to 440Hz or 120 to 370VDC.

Rated for operation from 0°C to 70°C ambient, the ZP models derate linearly to between 25 and 50% load at 70°C. The units can be operated with either convection or forced-air cooling.

Lambda's ZP series power supplies meet EN61000-4-X immunity and Class B EMI standards. They are also safety approved to UL60950, CSA60950 and EN60950 specifications and are CE marked. RoHS compliancy is expected by December.

The ZP series is available now, with prices starting at $18 each in OEM quantities. More information can be found on Lambda's Web site,
