Low noise and good dynamic response
The PowerFlex regulation system used on the CPX400D & DP combines a high
frequency pre regulator with a linear post regulator to give both low noise
and good transient response. Each output can operate in constant voltage or
constant current mode with automatic crossover and mode indication.
Precision metering and remote sense
Separate voltage and current meters on each output give a resolution of 10mV
and 10mA. The fixed resolution avoids the misinterpretation of readings that
can occur with auto-ranging 3 or 3½ digit meters where the decimal point
position moves as the reading changes.
Coarse and fine voltage controls are provided. The current control is
logarithmic enabling low current levels to be set accurately. A View Settings
button enables limit settings to be checked and adjusted at any time.
Each output incorporates remote sense terminals that can be enabled or
disabled at the flick of a switch. Remote sensing is essential for maintaining
precise regulation at the load and true metering of the load voltage.
Compact design uses minimum bench or rack space
Despite the high power output of 840 watts, the CPX400D & DP has a small
bench footprint taking up less space on a crowded bench.
For rack-mount applications the half-rack by 3U case size enables two units
(providing four outputs) to be fitted into a single rack slot.
Range control offers even more flexibility
As an alternative to PowerFlex operation (60V/20A subject to a power limit),
the CPX400D & DP can be used as conventional fixed range power supplies of
either 60V/7A or 20V/20A at the press of a button.
Fixed range mode ensures that, whatever the load, the output can only
be in constant voltage or constant current mode and never in power limit.
Additionally finer resolution is provided on the current or voltage controls
respectively.
A further button offers full customisation of voltage and current limits which
can be set to suit the users application. This has the advantage that the
controls cover the exact voltage and current range required, providing easier
setting and reduced risk of error.
For example, the range could be set to 30V and 14A to create a 30 volt PSU of
maximum current capability. Alternatively it could be set to 5V and 3A if this
was all that was required for a particular application.
Safety binding-post terminals
CPX series power supplies are fitted with the new TTi designed output
terminals. These can accept a 4mm safety plug with rigid insulating sleeve,
a requirement specified by an increasing number of laboratories for safety
reasons.

GPIB, RS-232, USB and LAN interfaces with LXI class C
compliance (CPX400DP only)
Compact ½ rack case; additional rear terminals on CPX400DP
- GPIB, RS-232, USB and LAN interfaces; LXI class C compliance
Bench and System use - CPX400DP
The CPX400DP is a bus programmable version of the CPX400D which includes
all of the 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.
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

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*.
