2. COMPONENT IDENTMFICATION AND SPECIFICATION
2.1. GENERAL DESCRIPTION
SM-32 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
SM-32 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)
