Water Cooled Switchmode Power SupplyDynapower offers the latest in water-cooled switchmode power supply, featuring an innovative design to provide users with an operational and installation advantage. Dyanapower’s water-cooled switchmode power supply is a flexible, easy to use rectifier with <2% AC RMS of full-scale ripple, 1% regulation over the operating range and a power factor of up to >0.99. Our high-efficiency, water-cooled switchmode power supply design offers a conversion efficiency that is greater than standard SCR type rectifiers with DC output capabilities of up to 900kW.

The water cooled design has been optimized to be as small as possible. All models are supplied with a NEMA 4X enclosure suitable for corrosive environments. Water cooled units include a touch-pad interface board allowing for advanced functions such as ramp, cycle, pulse, amp-hour counter and a program mode allowing any combination of these functions.  Numerous standard output ratings for both air and water cooled units are available in stock and readily available for shipment, with non-standard ratings and requirements designed to order.
