Aim-TTi QPX Series

Aim-TTi QPX Series Bench/System DC Power Supply with PowerFlex or PowerFlex+ regulation, Single or Dual Outputs up to 1200 watts, with/without Digital Remote Interfaces

QPX series laboratory power supplies are designed to provide flexibility in the choice of voltage and current so as to meet multiple diverse applications. Voltages up to 80V and currents up to 50A are available within a defined power envelope.

Unlike most power supplies of this power level, the QPX series is well suited to bench top applications in addition to system use.


A conventional PSU has a fixed current limit giving a power capability that reduces directly with the output voltage. The Aim-TTi PowerFlex and PowerFlex+ regulation systems enable higher currents to be generated at lower voltages within an overall power limit envelope.

For PowerFlex+ models the output can provide more than six times the current of a conventional PSU of the same maximum voltage and power. For PowerFlex models the increase is three times


PowerFlex and PowerFlex+ use either a balanced multi-phase converter system or linear final regulation to minimise ripple and improve dynamic performance. This provides unusually low noise for thepower level coupled with good transient response


When measuring rapidly varying loads it can become difficult to get accurate readings from the current meter. By selecting meter averaging, the reading is stabilised by averaging the last four readings to reduce the speed and extent of the variation.


Variable trips for over-voltage and overcurrent are provided on each output. Unlike a limit setting, the trip setting turns the output off and provides a different level of protection.

For example, when repetitively testing a unit which normally takes a peak current of 10A, the current limit could be set to 11A and the OCP to 10.1A to ensure that a faulty unit will trip the supply off and not be damaged by over dissipation. The output trip can also be activated by other fault conditions including over temperature and remote sense mis-wiring. The cause of the trip is shown on the display.
