Aim-TTi CPX400DP Power Supply Twin 420W PowerFlex

The Aim-TTi Twin CPX400DP 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 Aim-TTi Twin CPX400DP design 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 and current combinations include 60V/7A, 42V/10A, 28V/15A, and 20V/20A.

The PowerFlex regulation system used on the Aim-TTi Twin CPX400DP 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.
