What is Auto-ranging supplies and why is it important?

Auto-ranging power supplies offer the potential to save on equipment costs and energy. Here we discover more on utilizing an auto-ranging programmable DC source, like the PSI 9000 DT.

This high-end and most versatile programmable desk-top laboratory power-supply series is based upon a high-performance FPGA controller unit with up to 16-bit resolution. It features the superior flexible ”auto-ranging” output for a usage at either high voltage or high current as required within the nominal power rating. It includes a sensitive intuitive-to-operate TFT touch panel with up to 5-digit resolution, giving access to the integrated functions such as function generator, internal resistance/battery simulation, alarm manager etc. It provides for a highly stable DC output with extremely low noise/ low ripple, thus aiming at replacing linear-technology power supplies on the R&D engineer’s bench. For external control, this series it is equipped with a 3-way interface (isolated analogue 0-10V, USB and Ethernet). An optional 19” 2U kit is available for 19” rack integration. This series is a perfect instrument for R&D bench top usage.

   
  • FPGA controlled, up to 16 bit resolution.
  • For demanding low-noise/low ripple laboratory application, R&D
  • Flexible auto-ranging output, constant U, I, P and R mode.
  • Function generator, photovoltaic,- fuel-cell- and battery simulation
  • Sensitive TFT touch display of up to 5 digits.
  • Isolated interfaces: Analogue 0-10V, USB, Ethernet.
  • Attractive desk-top housing with handle, optional 19” 3U adaptor
  • IEC 320-C14 AC input receptacle, DC output safety terminals

Why should I choose PSI 9000 DT? The advantages are listed below:

  • Auto-ranging Output
  • Highly isolated structure, therefore much less sensitive against disturbances under operation
  • EMI compliant to EN 61000-6-3, EN 55022 class B
  • Fast discharge of output capacitance to IEC 1010
  • Minimum output ripple: Owing to a special filtering, the HF and LF output ripple are reduced to a level closing up to those of linear technology power supplies
  • Standard on-board 3-way interface: Analogue 0-5V/0-10V, USB, Ethernet/LAN or GPIB
  • TFT Touch Display with 64.000 colours with integrated comfortable function generator
  • Integrated R-Mode (inner-resistance simulation), to simulate batteries
  • Self-calibration function
  • High-performance FPGA (Field-Programmable-Gate-Array Lattice ECP3LFE17EA) allowing up to 10 times faster programming-reaction time
  • High resolution of up to 16 Bit
  • Voltage accuracy 0.1% of nominal
  • Professional user/control software for up to 20 devices (license fee applies)
  • Safety to IEC/EN 61010
