Lambda’s ZP series power supplies meet EN61000-4-X immunity and Class B EMI standards.
Lambda announced a new family of power supplies in the industry-standard 2 x 4-in. format. ZP series power supplies are said to be ideal in test-and-measurement equipment, data communications, LED signage, point-of-sale displays, and other applications.
Units are available in three output configurations. A 20- to 60-W single-output version includes popular voltages, 3.3-48 V, and 30-50-W dual- and triple-output versions provide a choice of output combinations and polarities. Typical efficiency for the 48 V models is 88%. All three configurations accept a broad range of input voltages: 90-264 V ac, 47-440 Hz or 120-370 V dc. Rated for operation from 0-70 °C ambient, the ZP models derate linearly, 25-50% load at 70 °C.
The units can be operated with convection or forced-air cooling. They also are safety approved to UL60950, CSA60950, and EN60950 specifications and are CE marked. Prices start at $18 each in OEM quantities.
