Lambda: Compact PCB Power Supplies
PCB power supplies.
San Diego, CA — Lambda has unveiled its latest additions to its ZPSA series of compact PC board-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-in.), making it a suitable choice for applications such as LED signs and lighting.

The power supplies are also suitable for use in point-of-sale equipment, computer peripherals, datacom, telecom, video/audio routers and test & measurement equipment.

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. According to the company, typical efficiencies are up to 88 percent. These models are rated for operation in a convection-cooled environment from 0 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, the company is offering these supplies as either an open-board configuration with Molex input/output connectors, or as a "/P" version with pins for PC board 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 a suitable 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.
