CPX400D
High accuracy four digit
meters have a fixed resolution
for consistent readings at-a-
glance.
Range Control gives a choice
of PowerFlex (60V/20A) or
fixed range operation (60V/7A
or 20V/20A).
True analog controls make
adjustment quick and simple.
Voltage sensing can be
changed between local
and remote at the flick of a
switch.
Safety binding post terminals
can accept fixed-shroud 4mm
plugs** as well as normal
plugs, bare wires, and fork
connectors.
The CPX series is a different type of laboratory power supply designed to meet
the need for flexibility in the choice of voltage and current.
A conventional PSU has a fixed current limit giving a power capability that
reduces directly with the output voltage.
The TTi PowerFlex design of the CPX series enables higher currents to be
generated at lower voltages within an overall power limit envelope.
Each output can provide considerably higher current than a conventional PSU
of the same maximum voltage and power (see power curve).
Example voltage & current combinations include 60V/7A, 42V/10A, 28V/15A,
and 20V/20A.
Building upon success
The CPX400D & DP are the latest models in the CPX series and were developed
from the CPX400A, one of the most successful power supplies ever.
Analog controls with digital stability
As technology has changed, many products have moved from analog controls
to digital ones. Although digital controls suit many instruments, they do not
necessarily suit a bench power supply.
Customer research shows that many users prefer the speed and simplicity of
conventional analog controls for setting voltage and current. Digital controls
may offer greater precision, but often at the expense of ease-of-use. With this
in mind, the CPX400D retains the true analog controls of its predecessor.
The main disadvantage of analog controls is stability and security. The settings
of analog potentiometers can drift over time. More importantly, the settings
can be changed accidentally with potentially serious consequences.
The CPX400D incorporates S-Lock. One press of the Lock button transfers
control of voltage and current from the analog controls to internal digital
circuitry. This offers not just complete security, but exceptional stability as
well with each setting controlled by an instrumentation quality DAC.

Isolated voltage tracking for maximum flexibility
The two outputs of the CPX400D are completely independent and electrically
isolated from each other.
With V-Track selected, the two outputs remain electrically isolated, but the
voltage control of the Master output sets an identical voltage on the Slave
output.
This enables the user to create two rails of either
polarity and to reference them to different grounds
if necessary (e.g. digital ground and analog ground).
Alternatively the outputs can be wired in series or
parallel to create a voltage capability up to 120V or
a current capability up to 40A with the voltage set
using a single control.
Independent and simultaneous output control
The Both On/Both Off button is in addition to the individual switches for each
output, and allow both outputs to be turned on or off synchronously by a
single button press.
Synchronous switching of the outputs is of increasing importance for circuitry
which can be damaged if one voltage rail is present without the other.

DC output switches enable
voltage and current to be set
up before connecting the load.
Both On/Off provides
synchronous switching of the
outputs.
Isolated voltage tracking
facilitates tracking voltage
rails or control for series or
parallel wiring (120V max. or
40A max.).
