Liquid-Cooled Sealed Automatic Solid State DC Power Converter
Liquid-Cooled Sealed Automatic Solid State DC Power Converter
SASSC liquid-cooled D.C. power conversion systems are designed for a broad range of surface finishing applications. These include electroplating, electropainting, anodizing and galvanizing.
Because all circuitry and components used in SASSC rectifiers are environmentally protected in sealed cabinets, these units are ideal for corrosive environments.
SASSC D. C. power supplies feature unique two-stage cooling systems designed to prolong the life of all sub-assemblies and components. In the first stage, a coolant continuously bathes components in a closed-loop system. The second stage maintains the temperature of the coolant automatically.
A liquid-to-water heat exchanger removes heat from the coolant solution using an outside fresh water source. This technology prevents the fresh water from coming in contact with electrical components, and minimizes consumption and maintenance requirements.
PEC designs and manufactures all SASSC rectifiers completely in-house. Our transformers have the lowest failure rate in the industry because of our attention to detail. Circuit boards are tested at elevated temperatures. Complete systems are run at full output to verify performance. As a last production check, all safety interlock circuits are validated prior to final inspection and shipping.
