ABOUT THIS MANUAL
This manual contains user information for the DCS Series System Supplies, 3000 Watt models. It
provides information about features and specifications, installation procedures, and basic functions
testing, as well as operating procedures for using both basic and advanced functions. It also
includes parts lists for the assemblies used in the system supply, and Internet links to access
schematics and circuit descriptions.
This manual is designed for the user who is familiar with basic electrical laws especially as they
apply to the operation of power supplies. This implies a recognition of Constant Voltage and
Constant Current operating modes and the control of input and output power, as well as the
observance of safe techniques while effecting supply or pin connections and any changes in switch
and jumper settings. The more knowledgeable user will find that the detailed schematics and circuit
descriptions available on our website will enable a greater flexibility in troubleshooting and in
configuring new applications.
Section 1 Introducing the 3000 Watt System Supply
describes the power supply, lists its
features, and provides tables of specifications.
Section 2 Installation
reviews safety and inspection procedures, then goes through the basic
set up procedures. Directions for the assembling of the AC input connector, for the testing of basic
functions, and for connecting the load are also included.
Section 3 Basic Operation
provides procedures for local programming mode operation (Constant
Voltage and Constant Current) and remote sensing.
Section 4 Advanced Operation
covers remote programming mode operation as well as
procedures for using advanced programming features such as Over Voltage Protection (OVP),
Output Power ON/OFF, and Remote Monitoring. Procedures for using multiple supplies in series,
in parallel, and in split supply configurations is also provided.
Section 5 Theory of Operation
provides a block diagram of the power supply, an explanation of
the functions within each block, and more detailed descriptions of the circuitry.
Section 6 Servicing the 3000 Watt System Supply
covers maintenance, calibration, and repairs
and features parts lists.
Section 7
contains a link to the Elgar website to access the schematics for the supply's component
assemblies and an interconnection diagram. Note that you must have a password to access these
drawings.
Section 8
is reserved for application notes.
