Aim-TTi CPX400S Power Supply Single 420 'PowerFlex'

The Aim-TTi CPX400S is a new single output version of the best selling CPX400 series. The ultra-compact design (quarter rack 3U) takes up minimum space for bench or system use. PowerFlex regulation enables the 420W of power to be configured to suit each specific application.

The PowerFlex regulation system used on the Aim-TTi CPX400S 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.

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.
