PULS QTD20.241 DC/DC Converter
Introduction
Modern machines typically use maintenance-free ACmotors which are controlled by frequency converters or servo amplifiers. Such devices have an intermediate DCbus where all individual drives are connected.
The QTD20 DC/DC converter 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.
The intermediate DC-bus is usually unfiltered and has high EMI noise so the QTD20 has a very robust input stage and an appropriate input filter included. Additionally, the QTD20 is UL 508-approved and is equipped with input fuses that are rated and tested for 600 VDC applications.
