CPX400D - Dual 420 watt PowerFlex dc power supply (840W total)

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 for the CPX400D include 60V/7A,

42V/10A, 28V/15A, and 20V/20A.

View and adjust setting limits

at any time.

Custom Limits enables the

analogue controls to cover

any voltage or current range.

Voltage sensing can be

changed between local

and remote at the flick of a

switch.

True analog controls make

adjustment quick and simple.

Safety binding post terminals

can accept fixed-shroud 4mm

plugs** as well as normal

plugs, bare wires, and fork

connectors.

High accuracy four digit

meters have a fixed resolution

for consistent readings at-a-

glance.

S-Lock digitally locks voltage

and current settings at the

touch of a button.

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.).

Individual over-voltage

protection for each output.

Range Control gives a choice

of PowerFlex (60V/20A) or

fixed range operation (60V/7A

or 20V/20A).

Building upon success

The CPX400 series, now comprising five models, was 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 CPX400 series 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 CPX series now 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.



Low noise and good dynamic response

The PowerFlex regulation system used on the CPX400 series 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 CPX400 series 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.

Single output, ultra compact design

The CPX400S is a single output version of the CPX400D providing up to 60 volts

and 20 amps within its 420 watt power envelope.

It is housed in a ¼ rack width 3U high case that uses the minimum possible

space for either bench use or rack mounting.

Three variants

The single output version of the CPX400 is available in three variants. The

CPX400S has manual control only, for conventional bench-top use. The

CPX400SA adds isolated analogue remote control plus duplicate rear terminals.

The CPX400DP has digital remote control via USB, RS-232, GPIB and LAN (LXI)

along with duplicate rear terminals (see next page).

CPX400SA - isolated analogue remote control

Some applications require analogue remote control rather than digital. The

CPX400SA has fully galvanically isolated voltage driven remote control

for both voltage and current. In addition, voltage and current front panel

settings are provided as non-isolated control voltages, enabling master-slave

configurations to be used.

CPX400SP - digital remote control

(see next page)

Safety binding-post terminals

All CPX series power supplies are fitted with the new TTi designed output

terminals. As well as acting as conventional binding posts for bare wires,

spade connectors, or standard 4mm plugs, these can accept a 4mm safety plug

with rigid insulating sleeve, a requirement specified by an increasing number

of laboratories for safety reasons.

Limited opening length

combined with raised insulated

shoulders also make these

terminals “touch proof” for

voltages up to 250V.

New CPX400SP single output with digital remote control

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.
