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.
