Control Transformer T1
A control voltage of AC 230 V is required in converters of size classes G
and H for the contactor fan and pump. This voltage is obtained from the
applied line supply voltage using an installed T1 control transformer.
In devices with voltage class 4: 3 AC380 V – 480 V, the control
transformer is designed primarily for the following power supplies:
•
Voltage: AC 380 V / 400 V / 415 V / 440 V and 460 V
•
Voltage tolerance: ±15 %
•
Frequency: 50 / 60 Hz
The control transformer has been set to a line supply voltage of AC 400 V
at the factory.
For a converter with a line input supply voltage of 3 AC 480 V, the cable
must be removed from transformer terminal 400 V and connected to
transformer terminal 460 V.
For a converter with a line input supply voltage of 3 AC 500V, switching
terminals is not required. The transformer is laid out for a line supply
voltage of 500 V.
