TDK-Lambda Americas has upped the output power of its ZPSA Series of compact open-frame AC/DC power supplies with the introduction of a 100-Watt model. The single-output ZPSA100 accepts a wide input voltage range, has a low profile (1.3”) and industry standard footprint (3.0” x 5.0”), making it appropriate for applications such as LED signage and lighting, point-of-sale equipment, datacom, video/audio routers and test & measurement equipment. These 100-Watt supplies are available with the most popular single output voltages from 5 V to 48 VDC. Offering a typical efficiency of up to 90 percent, these models are suited for operation in both convection or air cooled environments from 0°C up to 70°C, with appropriate derating. A green LED is provided as an indicator that the power supply is on, and other standard features include over voltage and short-circuit protection. These supplies are offered in an open-board configuration with Molex input/output connectors.
