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. 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:

400V-15%	up to	480+10%
50 or 60 Hz		(Dip-switch selectable)

The maximum input power of the internal switching power supply is 100W, and the supplied voltages are:

+/-15V 500mA	Control card
+24 V 2A	Fan power supply (if present) and auxiliary functions (regulator
	terminals power supply)
