840 watt PowerFlex dual power supply adds flexible interfaces
The new
CPX400DP is the latest in the CPX series of PowerFlex regulated PSUs
from TTi and is the first to incorporate digital remote control
interfaces.
Based around
the power electronics of the widely adopted CPX400A, it incorporates
important new manual control features in addition to the digital
interfaces. These
include settings lock, isolated voltage tracking, and synchronous
switching of the two outputs.
To achieve
maximum flexibility for remote control applications, RS-232, USB,
GPIB and LAN (Ethernet) interfaces are all provided as standard.
The LAN interface is compliant with LXI (LAN eXtensions for
Instrumentation).
The TTi
PowerFlex design offers a constant-power capability allowing higher
output current at lower output voltages.
Each output can provide 60 Volts at a maximum current of 7
Amps. As the voltage setting is reduced the output current
capability increases up to a maximum of 20 Amps.
The CPX400DP is
a dual output PSU with two completely independent and isolated
outputs each with a 420W capability. The outputs operate in constant
voltage or constant current mode with automatic crossover and mode
indication. Isolated voltage tracking allows easy control for either
series or parallel wiring enabling up to 120V or 40A to be produced.
The power
supply uses true analogue controls, but incorporates an S-Lock
function which transfers control of voltage and current from the
analogue controls to internal digital circuitry for stability and
safety.
Each output has
its own on-off switch, but an additional synchronous on/off switch
can be used to ensure that both outputs are operated together, an
important function for circuitry that can be damaged if one voltage
rail is present without the other.
The CPX400DP is
housed in a compact and robust steel case which is half-rack width
and takes up very little bench space.
The size is 210 x 130 x 350mm, and the weight is 7kg.
A rack kit is available that can mount one or two units.
