Overview
Product overview
Transformer-rectifier equipment for impressed-current cathodic protection of suitable pipelines, tanks, marine and industrial structures.
Function
A transformer-rectifier converts AC input to controlled DC output for impressed-current cathodic protection.Control
The published product description includes constant-potential and constant-current control, soft start, alarm / overcurrent functions, self-check and display functions.Remote monitoring
The current page describes RTU remote transmission / control and lightning-protection and anti-interference features.Project configuration
AC supply, DC output, control mode, enclosure, protection functions and communication interface should be confirmed from the project specification.Technical information
