The Aim-TTi QPX750SP 750-W single-output dc power supply can provide voltages between 80 V at 9.4 A and 12 V at 50 A with a maximum resolution of 0.1 mV. 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 50 V 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-in. 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.
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.
