Dynapower offers the latest generation of air-cooled switchmode DC power supplies. Featuring an innovative design that provides operational and installation advantages, Dynapower air-cooled switchmode power supplies provide the reliability and functionality you need, while maximizing your space and cost savings.

The air-cooled switchmode DC power supply is a solid state AC to DC power conversion system. The system functions by first rectifying the AC input to an unregulated DC voltage. This intermediate DC voltage is then chopped using pulse-width modulation through an H-Bridge configuration into a high-frequency transformer. The output of the transformer is rectified and filtered to provide a precisely controlled high current DC output with <2% AC Vrms content. The high switching frequency enables a smaller package, less ripple, higher efficiency, and provides for a faster control loop.

New Rectifier Financing Programs

Dynapower is now offering low interest rectifier financing programs in partnership with Lease Corporation of America. Get the equipment you need now and pay for it over time. You can also take advantage of IRS Section 179 and deduct 100% of the cost leased or purchased equipment in the first year that the equipment is put into service, saving your business thousands of dollars on your tax bill.
