Saelig Introduces New Versatile AIM-TTi PowerFlex+ 750W DC Laboratory Power Supply

The Aim-TTi QPX750SP is the first of a new Bench/System Single Output PowerFlex+ DC Power Supply platform. It provides up to 80V or 50A at a maximum of 750W in a benchtop or rackmount housing.

Fairport, NY, USA: Saelig Company, Inc. announces the availability of the Aim-TTi QPX750SP 750W Single Output DC Power Supply that can provide voltages between 80V at 9.4A and 12V at 50A with a maximum resolution of 0.1mV. This laboratory power supply is designed to provide a flexible choice of voltage and current to meet multiple application needs. It is housed in a compact 3U half-rack-width case with front ventilation and low noise fan assisted cooling. Front and rear power and sense terminals make it suitable for use either on the bench or in a rack-mount system. The available RM460 4U rack kit can accept one or two QPX750SPs with ½U rack spacing above and below to provide full ventilation.

The QPX750SP features an SELV mode, an added safety feature where voltages above 50V require authorization from the user. The QPX750SP’s PowerFlex+ design uses a linear final regulation design, which minimizes ripple and improves dynamic performance. This design results in an unusually low noise/power ratio, coupled with good transient response.

Three operating modes for the QXP750SP are provided: Constant Voltage, Constant Current or Constant Power, with automatic cross-over dependent on output setting parameters CV, CC or CP mode indication in display.

A 4.3” color touch-screen simplifies operation and enables data entry via touch input in addition to the numeric keypad and rotary encoder. Comprehensive information is displayed for operational settings and limits for voltage, current, or power (watts). Equivalent resistance measurements of the connected load can be made at high currents using the remote sense terminals to create a four terminal connection. This gives more reliable results for long power leads or components such as magnetics and cables harnesses. 

  • Wide range of voltage/current combinations
  • Up to 80V and up to 50A within the same power envelope
  • Low output ripple and noise of <3mV rms at full power
  • High setting resolution of 1mV
  • Analog control interfaces for voltage and current
  • Bench or rack mounting, front and rear terminals
  • LAN (LXI), USB, (GPIB optional)

A comprehensive array of interfaces including USB, LAN/LXI and quasi-analog are standard, with GPIB available as an option. The QPX750SP is compatible with Aim-TTi Test Bridge software, providing graphical remote instrument control, logging, and sequencing.

Made by Aim-TTi, a leading European test equipment manufacturer, the Aim-TTi QPX750SP 750W Single Output DC Power Supply is available now from Saelig Company, Inc., Fairport, NY their technical distributor. For detailed specifications, free technical assistance, or additional information, please contact Saelig 1-888-772-3544, via email:, or visit
