DC-Sources - Switch mode

  • From 750 W to 1 MW
  • Output voltages up to 1,500 V
  • Output currents up to 50,000 A
  • Quiet operation, ensuring that it is pleasant to work within the vicinity of the unit
  • Very easy to control via front panel
  • Information via graphic display
  • Constant voltage, current, resistance, power operation and simulation of PV arrays
  • Create any type of voltage or current curve via memory card or digital interface (sequential operation)
  • Script operation, in conjunction with the Datalog function, enables an independent stand-alone test field to be set up
  • Standard integrated ATI 5/10 galvanically isolated analogue interface: 0 – 5 V or 0 – 10 V (user selectable) and RS232, master/slave (LAB/HP and LAB/SMS), soft interlock
  • Master/slave interface to parallel and series circuits (LAB/HP and LAB/SMS)
  • Filter functions which can be adjusted for analogue interface
  • Digital interfaces IEEE488, RS485, USB and LAN (optional)
  • SD card slot (optional)
  • Datalog function: Current operating values are saved to the memory card at adjustable time intervals, SD card (optional)
  • Voltage rise time and current rise time (U and I slopes) are adjustable
  • Umax and Imax can be set by the user in order to limit output voltage or output current
  • A switch-off time can be set for the unit once the start button has been pressed
  • Create U/I output characteristics which can be saved (e.g. for PV-Sim, shading)
  • “High speed” optional secondary rise and fall time for the DC output voltage is reduced by a factor of 10 compared to standard times, on average
  • Autorange optional down to 33%
  • OVP, OTP, UVP and OCP protective functions
  • Special versions available on request
