Compact 40W & 60W PCB Supplies Meet Class B EMI

SAN DIEGO, CA (September 23, 2008) - Lambda has unveiled its latest additions to its ZPSA series of compact pcb-mountable AC-DC power supplies. The new single-output ZPSA40 and ZPSA60 series accepts a wide input voltage range, has a low profile and industry standard footprint (2 x 4 x 1.07"), making it an ideal choice for applications such as LED signs and lighting, point-of-sale equipment, computer peripherals, datacom, telecom, video/audio routers and test & measurement equipment.zpsa40 60

These 40 and 60-watt supplies are available with the most popular output voltages from 3.3V to 48VDC. The outputs are floating so they can be used as either a positive or negative polarity. Typical efficiencies are up to 88%. These models are rated for operation in a convection cooled environment from 0°C up to 70°C with derating. A green LED is provided as an indicator that the power supply is on. Other standard features include overvoltage and short-circuit protection.

To maximize design-in flexibility, Lambda is offering these supplies as either an open-board configuration with Molex input/output connectors, or as a "/P" version with pins for PCB mounting..

Accepting a wide input voltage range of 90-264VAC (47-440Hz) or 120-370VDC, the ZPSA40 or 60 series is ready for use globally with no further configuration or input selection. Its industry standard footprint makes it an ideal choice as a drop-in replacement for existing supplies, while its low profile means that it can be installed in the most compact of applications. The ZPSA40 or 60 has global safety agency approvals per UL/CSA/EN60950-1; meets conducted and radiated EMC requirements of EN55022-B and FCC Class B (without additional filtering or components) and meets EN61000-4 immunity specs for greater reliability. All supplies carry the CE Mark and are RoHS compliant.

The ZPSA40 or 60 series are available now with prices starting at $15.75 each in 1000 piece quantities. More information is available at Lambda’s websites: and
