10. Technical data

Type voltage 230 Volt -57% +10%

400 Volt -57% +10%

500 Volt -57% +10%

Mains frequency all models 47Hz to 63Hz; f=6 Hz;

max. frequency change 5% per half wave

Load description ohmic load

transformer load

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.

Operating modes

TAKT = full wave pulse = default setting

(T0: 0.1 sec / 1.0 sec)

VAR = phase-angle control (only Thyro-A 1A)

QTM = fast half wave pulse (only Thyro-A 1A)

Set point inputs

The Power Controller Thyro-A has 2 set point inputs. The set point inputs are safely

disconnected from the mains (SELV, PELV).

Set point 1: External set point input signal ranges:

0(4)-20 mA R

= ca. 250 

0-5 V R

= ca. 44 k

0-10 V R

= ca. 88 k

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

system

Control characteristic

The control characteristic is established by the maximum value of the dimensions to

be controlled and the key values of the set point. Using these key values, the linear

control characteristic may be set as desired.

Each controller (e.g. temperature controller) whose output signal lies within the

range 0-20mA / 0-5 V / 0-10 V, can easily be adapted to the Power Controller.
