Operating instructions

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

: 0.1 sec / 1.0 sec)

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

= ca. 250k

0 - 5V R

= ca. 44k

0 - 10V R

= ca. 88k

Set point 2: Optional bus interface, connection from superset PC or automation

system.

Analogue output

Output: Signal level 0-10V, 0-20mA, 4-20mA

Maximum burden voltage 10V
