Transformer Rectifier    

Cathodic Protection rectifiers are designed for protection of underground metal constructions such as pipelines, oil wells against soil/electrochemical corrosion. CP rectifiers are suitable to adopt all kinds of reference electrodes, like Zn, Ag/AgCl, Cu/CuSo4 electrode.
 
Bullet1 Constant Volts/Amps/Ref Potential
Bullet1 Single and 3 phase power input
Bullet1 Rugged electronic control High voltage rated devices
Bullet1 Relatively easy to protect from lightning transients
Bullet1 Milliamps to thousands of amps output current
Bullet1 Soft start on power-up or after interruption
  OFF to ON  - suits DCVG surveys on pieplines
Bullet1 Optional remote control
