SWITCHMODE POWER SUPPLY
AIR COOLED
THE WORLD’S LEADING MANUFACTURER OF STANDARD AND CUSTOM POWER CONVERSION EQUIPMENT
24 Hour Technical Support and World Wide Service | UL, CSA and CE Compliant Designs Available
The 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 switched 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 smaller magnetics and filters, less
ripple, higher efficiency and provides for a faster control loop.
The air cooled design has been optimized
to be as small as possible and all models come standard with
a NEMA 4X enclosure suitable for corrosive environments.
Numerous standard output ratings for both air and water
cooled are available off the shelf, with non-standard ratings
and requirements designed to order.
