The open frame design has JST input and output connectors and suits chassis-mount applications. The TPP 100A-J is packaged in a compact 3 x 2 x 1.6 inch footprint, while the TPP 150A-J measures just 4 x 2 x 1.6 inches. The TPP 150 also includes a 12 VDC auxiliary output for powering a system fan. These small sizes result in a high power density product that takes up less space, allowing the designer to build a smaller product or have more room to add additional feature sets.
