Mains transformers are always needed when the mains voltage is outside of
the allowed nominal voltage of the component.
The mains voltage for grounded mains is generally adjusted with autotrans‐
formers.
The mains voltage for ungrounded mains is generally adjusted with isolating
transformers to prevent overvoltages between outer conductor and ground.
Short-circuit voltage of the isolating transformer: ≤ 4%
With HCS01 components, there are two applications that require autotrans‐
formers:
1. HCS01.1E-W00xx-A-02 components are used:
With a mains voltage of 3 AC 400 V, the voltage must be adjusted via
an autotransformer to use HCS01.1E-W00xx-A-02 components with an
input voltage range of 3 AC 110...230 V.
2. An MSM motor is used in conjunction with an HCS01.1E-W00xx-A-03
component:
MSM motors have been dimensioned for a voltage of 230 V. To operate
MSM motors at a mains voltage of 3 AC 400 V at an HCS01.1E-W00xx-
A-03 component, the mains voltage has to be adjusted to 3 AC 230 V
via an autotransformer.
