Dedicated Transformer

ACA 635 IGBT Supply Sections
WARNING! The ACA 635 must be supplied with a transformer
dedicated to drives and motors or equipment of equal or higher power,
or with a transformer equipped with two secondary windings, one of
which is dedicated to drives and motors. Resonances might occur if
there is capacitive load (e.g. lighting, PC, PLC, small power factor
compensation capacitors) in the same network with the ACA 635. The
resonance current might damage some unit in the network.
