The latest in the CPX series of PowerFlex regulated power-supply units from TTi incorporates digital remote control interfaces.

Based around the power electronics of the widely adopted CPX400A unit, the new supply 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 60V at a maximum current of 7A.

As the voltage setting is reduced the output current capability increases up to a maximum of 20A. 

The CPX400DP is a dual-output supply with two independent and isolated outputs, each with a 420 W capability.

The outputs operate in constant-voltage or constant-current mode with automatic crossover and mode indication. Isolated voltage tracking allows 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.

It measures 210x130x350mm and weighs 7kg. A rack kit is available that can mount one or two units.
