Type voltage
Additional gate voltage input
The additional gate voltage supply can take place with a.c. or d.c.
Mains frequency
Load description
ATTENTION
The induction of the load side transformer should not exceed 1.45T
in case of mains overvoltage when using grain-oriented, cold-rolled
plates = 1.2T nominal induction.
Betriebsarten
TAKT = full wave pulse = default (T
VAR = phase-angle control (only for types 1A)
QTM = fast half wave pulse (only for types 1A)
Set point inputs
The Power Controller Thyro-A has 2 set point inputs. The set point inputs are
indirectly connected to the mains (SELV, PELV).
Set point 1: External set point input signal ranges:
0(4) - 20mA R
0 - 5V
0 - 10V
Set point 2: Optional bus interface, connection from superset PC or automation
system.
