Analog Output; Current Transformer; Voltage Transformer - AEG THYRO-A Operating Instructions Manual

4.7 Analog output

The electrical values for current and voltage at the load are recorded by the Thyro-A
Power Controller and can be displayed using an external measuring device or a
graph recorder. Connection to terminals X2:9 (+), against X2:5 ground 1.5mm 2
grid 3.5. The selectable signal levels are 0-10V, 0-20mA, 4-20mA. The analog out-
put is updated in every supply period (refer to 3.2.4).
The following values may be given:
• load voltage
• load current
• Actual output

4.8 Current transformer

All Thyro-A types have one current transformer per path in their power section.
The current transformer only has local mode wiring.

4.9 Voltage transformer

The load voltage is recorded by the measuring signal given by the supply voltage.
C
This value is linked with the control angle or the pulse ratio
* √ (T
U = U /T ). The voltage transformer only has local mode wiring.
