    CS300 Chapter 2 - COMPONENT IDENTIFICATION AND SPECIFICATION 2.1 GENERAL DESCRIPTION CS300 is a half-controlled three phase AC/DC converter for supplying DC link voltage to a series of AC Drives, with C and D terminals parallel connected. The precharge of the drive capacitors (time setting set via dip-switches) is done by partializing the mains voltage via a thyristors bridge.

  • Page 14: Converter Size Selection

    GEH-6639 2.6 CONVERTER SIZE SELECTION Within the specified voltage field, the CS300 converter supplies the same rated direct current independently of the voltage itself. The increase of the output voltage causes an increasing in the transferred power, whereas inverters are devices with a typically constant transferred power (the supplied current decreases with the increasing of the output voltage).
