Summary of NEW VERSATILE AIM-TTI POWERFLEX+ 750W DC LABORATORY POWER SUPPLY
The Aim-TTi QPX750SP is a versatile 750W Single Output DC Power Supply offering up to 80V or 50A. Designed for benchtop or rackmount use, it features a compact 3U case with fan-assisted cooling and front/rear terminals. Its PowerFlex+ linear design ensures low noise and excellent transient response. The unit includes SELV safety mode and supports Constant Voltage, Current, and Power operating modes with automatic crossover.
Parts used in the Aim-TTi QPX750SP Project:
- Aim-TTi QPX750SP 750W Single Output DC Power Supply
- Rack kit RM460 4U
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.

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 the display.
