A new type of bench PSU
The CPX200 is designed to meet the need for flexibility in the choice of
voltage and current capabilities. Todays engineers often need the voltage range capability of a 0 to 35V
PSU and the current capability of 10A PSU. Normally, however, the maximum
voltage and maximum current are not required simultaneously. A conventional
bench PSU has a fixed current limit giving a power capability that reduces
directly with the output voltage.
PowerFlex design
The TTi PowerFlex design of the CPX200 enables higher currents to be generated
at lower voltages within an overall power limit envelope.
Each output can provide 35 Volts at a maximum current of 5 Amps. As the
voltage setting is reduced the output current capability increases up to
a maximum of 10 Amps.
This is achieved by using the latest switch-mode technology. Advanced techniques
are used to achieve noise and RFI figures comparable with good linear PSUs.
As a result the CPX200 can be used with confidence in sensitive environments.
Twin independent outputs
The CPX200 is a dual output PSU with two completely independent and isolated
outputs each with a 175W capability. The outputs operate in constant voltage
or constant current mode with automatic crossover and mode indication.
Each output has its own on-off switch.
If required, the outputs can be wired in series or parallel to achieve
voltages up to 70V or currents up to 20A.

Compact and convenient
The CPX200 is housed in a compact and robust steel case which is half-rack
width and uses little bench space. It is lightweight to transport and generates
much less heat than a conventional PSU of similar power.
No cooling fan is used resulting in a power supply which is silent in operation.
Precision adjustment and metering
The CPX200 incorporates separate high resolution voltage and current meters
for each output using bright 12.5mm (0.5") LED displays.
Coarse and fine controls permit the output voltage to be set within 10mV.
The current limit control is logarithmic to give good resolution at low
current settings. Remote sense terminals are provided to allow the effects
of connection lead resistance to be eliminated.
When each output switch is set to ‘OFF’, the meters display the set levels
enabling them to be set accurately before connection to the load.
Safety and protection
The CPX200 is designed and manufactured to meet the latest safety and EMC
standards. Comprehensive protection includes an adjustable overvoltage
trip for each output. This can be accurately set anywhere in the range
3.5V to 38.5V.
