The Corrpro® Touch-Free Air-Cooled Rectifier series is designed to meet industry requirements for operator-safe rectifiers (touch free). This is achieved by limiting accessibility to energized parts within the rectifier, depending on which door is accessed. The Touch-Free Rectifier has CSA/UL approved quality components and our certified manufacturing methods achieve an advanced safety rectifier for the cathodic protection industry.
The mode of operation is performed by stepping down the incoming AC power, then isolating and rectifying it to a controlled DC output. Input overload & short circuit protection is provided by magnetic-trip circuit breakers. Output protection is by means of a fusing device in the transformer secondary (optional secondary protection by means of our FRM [fuse replacement module]). Primary AC/DC lightning protection is provided by high energy metal oxide varistor (MOV) arrestors. Secondary surge suppression is by disk-style MOVs. The DC output is controlled by rotary tap switches with 25-steps of combined adjustment. Standard DC output meters are analog with the option of upgrading them to digital or CRC controller.
