Lambda Offers 20W Addition To PCB Mountable AC-DC Power Supplies
Lambda has unveiled its latest series of compact pcb-mountable 20W ac-dc power supplies. The single output ZPSA20 series accepts a wide input voltage range, has a low profile (0.79") and industry standard footprint (2 x 3.5"), making it a suitable choice for applications such as computer peripherals, datacom, telecom, point-of-sale equipment, LED signs and lighting, video/audio routers and test & measurement equipment.
These 20W pcb-mountable supplies are available with the most popular output voltages including 3.3, 5, 9, 12, 15, or 24Vdc. The outputs are floating so they can be used as either a positive or negative polarity. Typical efficiencies are up to 82%. 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, 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 85-264Vac, the ZPSA20 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 it is claimed that its low profile means that it can be installed in the most compact of applications. The ZPSA20 has global safety agency approvals per UL/CSA/EN60950-1; meets conducted and radiated EMC requirements of EN55022-B/FCC Class B (without additional filtering or components) and meets EN61000-4 immunity specs. All supplies carry the CE Mark and are RoHS compliant.
The ZPSA20 series is available now with prices starting at $12.50 each in 1000 piece quantities.
