100 Watt Open-Frame Power Supplies

TDK-Lambda Americas, a group company of TDK Corporation, 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 new single-output ZPSA100 accepts a wide input voltage range, has a very low profile (1.3") and industry standard footprint (3.0" x 5.0"), making it an ideal choice 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 5V to 48Vdc. Offering a typical efficiency of up to 90%, these models are well-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.

Accepting a wide input voltage range of 90-264Vac (47-440Hz) or 120-370Vdc, the ZPSA100 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.

TDK-Lambda's ZPSA100 series is approved to national and international safety approvals, including IEC/EN/UL/CSA60950-1 (Edition 2) meets conducted and radiated EMC requirements of EN55022-B and FCC Class B (without additional filtering or components) and meets EN61000-4 immunity specifications for greater reliability. All models in the ZPSA100 series carry the CE mark, according to the LV Directive, and come with a two-year warranty.
These units are available now and economically priced from $40.00 each in 250 piece quantities.
