DCTron is especially designed to dissipate AC currents in systems with cathodic protection, while blocking DC currents, where due to the cathodic protection, direct connection to the earthing system is not possible. DCTron dissipates the AC currents while at the same time it maintains the cathodic protection operational. Additionally it is providing protection against lightning and surge currents of up to 100 kA (10/350 μs).
The decoupling main circuit, is consisted of a L–C filter with low AC voltage drop at the maximum AC dissipation current ), thus providing protection from touch and induction voltages. Also is limiting the leakage current to minimum in order to maintain the cathodic protection operational. Additionally it is equipped with a DC overvoltage protection circuit in case the DC voltage exceeds the limits.
