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. A diagnostic circuit allows detection of a mains power supply dip for
system use.
NOTE!
The direct parallel connection of the outputs (U2,V2,W2 terminals) of two or more inverters
is not possible !
2.2 POWER SUPPLY
CS300 converter can be connected to the three phase power supply having the following characteristics:
The maximum input power of the internal switching power supply is 100W, and the supplied voltages are:
