HES SERIES 150 WATT
Powering Communications and Technology
DESCRIPTION HES single output DC/DC converters provide up to 150 Watts of output power in an industry standard, half-brick package and footprint. These units feature ultra-high efficiency, Class A conducted noise specs, and fixed switching frequency. The HES is designed with open-frame packaging, along with planar magnetics to provide maximum useable power with minimal thermal constraints. The HES is especially suited to harsh telecom, networking, and industrial applications, and is fully compatible with production board washing processes. TECHNICAL SPECIFICATIONS
