Datasheet

Bench and System use
The CPX400SP, CPX400DP and CPX200DP are a bus programmable version
of the CPX400S, CPX400D and CPX200D respectively, and include all of
their manual control features plus comprehensive digital interfaces and rear
terminals.
Rear output terminals
Power and sense terminals are duplicated on the rear panel for rack mount
applications or other situations where rear connection is more appropriate.
Digital remote control
To meet the varying needs of today’s engineers, a comprehensive array of
interfaces is provided. RS-232, USB, GPIB and LAN (Ethernet) with LXI support
are provided as standard. Each of the digital bus interfaces provides full control
of voltage, current, and output on/off, plus read-back of voltage, current and
status. The interfaces are at ground potential and are opto-isolated from the
output terminals.
GPIB
The GPIB interface is compliant with IEEE-488.1 and IEEE-488.2. Currently
GPIB remains the most widely used interface for system applications.
RS-232
An RS-232/RS-423 interface is provided for use with legacy systems. This type
of serial interface remains in common useage and is perfectly satisfactory for
the control of power supplies because data speed is not an issue.
USB
USB provides a simple and convenient means of connection to a PC and is
particularly appropriate for small system use. A USB driver is provided which
supports Windows 2000, XP , Vista and Windows 7.
LAN (Ethernet)
The LAN interface uses a standard 10/100 base-T Ethernet hardware connection
with ICMP and TCP/IP Protocol for connection to a Local Area Network or direct
connection to a single PC. This interface supports LXI and is highly appropriate
for system use because of its scalable nature and low cost interconnection.
LXI Compliance
The LAN interface is compliant with LXI-C. LXI (LAN eXtensions for
Instrumentation) is the next-generation, LAN-based modular architecture
standard for automated test systems managed by the LXI Consortium, and
is expected to become the successor to GPIB in many systems. For more
information on LXI and how it replaces GPIB, or operates along side it, go to:

IVI Driver
An IVI driver for Windows is included. This provides support for common high-
level applications such as LabView*, LabWindows*, and HP/Agilent VEE*.

A new variant of the CPX series
The CPX200D replaces the best-selling CPX200, many thousands of which are
in use across the world.
A wider PowerFlex range extends maximum voltage from 35 volts to 60 volts,
whilst the maximum current of 10 amps is now available up to 16 volts rather
than 12 volts.
It includes all of the features of the CPX400D, described earlier on page 2, but
at a lower power level.
Existing CPX200 owners will appreciate the new features of S-Lock, Range
Control, Voltage Tracking and Synchronous On/Off.
For those requiring bus control, the CPX200DP includes a full set of digital
interfaces.
New CPX200D 360W dual
Dual 180 watt PowerFlex, 60V max. and 10A max.
