AUTOMATIC CP RECTIFIERS
UKZT-AU OPE X,X Y1
Cathodic Protection rectifiers "Don-U" are intended for protection of underground metal constructions (pipelines) against soil corrosion by a method of cathodic polarization. The CP rectifiers of this modification has all base properties of CPR "Don", but they have increased dimensions for better cooling of elements and blocks of the CP rectifiers in conditions of high temperature of an environment at high protective currents. Thus the adjusting sizes of the external case and internal rotary chassis of the rectifiers are kept, that allows universal application of the rectifiers of "Don", "Don-U" and "Don-TM" as on a design stage and at using. The rectifiers "Don-U" are made in two modifications:
-
UKZT-1U OPE X,X Y1 – The cathodic protection rectifiers with manual control of output parameters (without automatic);
- UKZT-AU OPE X,X Y1 – The automatic CP rectifiers with three regimes of work: manual control, automatic stabilization of output current (DC) and protective potential on protected construction. Also these rectifiers may be connected to some systems of remote control and operating. That function allows to provide remote control and operating of parameters (protective potential, output current and voltage) of the rectifiers. This function may be included on preliminary request of buyers and does not change the rectifiers cost.
All CP rectifiers "DON" and "DON-U" have next features:
-
Intuitively clear bodies of control;
-
Unique ergonomic design;
-
Unpretentiousness and safety in work;
-
Universality and interchangeability of blocks and parts of a case;
-
The compact and strong case from sheet steel 2мм;
-
High-quality and proof powder covering of metal details of the case;
-
Small weight
