  • - Logical signals with a level of no more than 1.5 V and a unit of 15V of positive polarity
The control unit consists of two boards located in a closed IP54 housing
The units are universal for all rectifiers

The units have control, monitoring and signaling equipment that provides:

  • - Switching on and off;
  • - Contactless switching on / switching off direct current;
  • - Switching to local or remote control;
  • - Switching to the selected type of work;
  • - Adjustment of direct current and voltage;
  • - Control of direct current and voltage;
  • - Automatic stabilization mode: for current, voltage, current density;
  • - Lamp signaling: on the presence of supply voltage, on the active state, in case of emergency shutdowns.
The reverse is provided by an additional
unit in IP 54 housing located on the rectifier door

Reversible units additionally provide:

  • - Lamp signaling about the output current polarity;
  • - Switching to manual or automatic reversing;
  • - Automatic reversing of the load current at separate setting of the duration of current pulses of forward and reverse direction. The initial current direction can be adjusted for direct or reverse polarity;
  • - Setting the flow time duration for the direct, reverse current and total time;
  • - Unipolar impulse current with separate setting of impulse and pause duration.
  • - Counting the total operating time both in manual and in automatic reversing mode.
  • - Switching to the selected initial direction of direct current;
