light signalling – light-emmiting diode
current reverse connection signal of type - current transducer signal in the rectifier current circuit
of type.
Carried out functions:
local current assignment of type; distant current assignment of type (with
electroplating decoupling); current stabilization of type; current measurement of type on signal with
current transducer of type; state control of rectifier units; drive control ÐÏÍ (operation mode –
automatics switching on signal from ØÓÄÍ; manual switching ÐÏÍ of separate transformers;
group manual switching). ØÓÒÑ provides possibility of consumed power limiting on external
signal.
