The new QPX600D from Aim-TTi is a dual-output 1.2kW power supply using the company's latest PowerFlex+ regulation technology to provide up to 80V or up to 50A on each 600W output. Whereas a conventional power-supply unit has a fixed current limit giving a power capability that decreases directly in proportion with the output voltage, the PowerFlex+ design of the QPX600D enables higher currents to be generated at lower voltages within an overall power limit envelope. Each output can provide more than six times the current of a conventional supply of the same maximum voltage and power. Examples of voltage/current combinations include 80V/7.5A, 60 V/10A, 40V/15A, 28V/20A, 18V/30A and 10V/50A. The QPX600D can be operated as two entirely independent and isolated power supplies, each with its own comprehensive graphic LCD display. Alternatively, multiple isolated tracking modes are available, including some intended for series and parallel operation with metering of total voltage or total current, respectively. This enables up to 160V or 100A to be provided when required. The two outputs can be switched on or off either independently or synchronously. Synchronous switching of the outputs is of increasing importance for circuitry which can ‘lock up' or even be damaged if one voltage rail is present without the other. The front-panel control system allows settings to be made using direct numeric entry, or via a spin wheel. Setting resolution is 1 mV or 10 mA, and a number of non-volatile settings stores are provided. Two versions of the product are available: one with analogue remote control only, and another with analogue and digital interfaces including USB, RS232, GPIB and LAN (Ethernet). The LAN interface is compliant with LXI class C (LAN eXtensions for Instrumentation). The QPX600D is suitable for benchtop or rack-mounted applications. It has built-in tilt feet and a 3U high rack-mount kit is available. To view the data sheet click here http://www.aimtti.co.uk/products-tti/pdf-brochure/psu-qpx600d-4p.pdf www.aimtti.co.uk
