1. GENERAL DESCRIPTION
Modern machines typically use maintenance-free AC-
motors which are controlled by frequency converters
or servo amplifiers. Such devices have an
intermediate DC-bus where all individual drives are
connected.
The QTD20 power supply can be connected directly
to the intermediate DC-bus. In case of a mains
failure, the QTD20 utilizes the power from the DC-
bus capacitors which are charged from the kinetic
energy of the motor until the motor has come to a
complete stop.
Intermediate DC-buses are not usually filtered and
have high EMI noise superimposed. The QTD20 has a
very robust input stage and an appropriate input
filter included.
