ET System LAB-SMSL Series DC Sources and Load, Voltage-controlled, 2-quadrant Operation

The ET System LAB-SMSL series are voltage-controlled DC sources with integrated load for 2-quadrant operation. The series covers a range of 3 kW, 4 kW, or 5 kW. The devices have a compact design and feature a quiet operation, ensuring that it is pleasant to work within the vicinity of the unit. They operate in constant current, voltage, resistance, and power mode (CC, CV, CR, CP) and allow the simulation of PV arrays. The devices offer various protective functions and a variety of features and options.

  • DC sources with integrated load.
  • Voltage-controlled for 2-quadrant operation.
  • 3 kW, 4 kW, or 5 kW.
  • Output voltages up to 600 V.
  • Output currents up to 200 A.
  • Compact design.
  • 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 (CC, CV, CR, CP) and simulation of PV arrays.
  • With integrated load; 300...2000 W voltage-controlled for 2-quadrant operation.
  • 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, soft interlock.
  • Digital interfaces (optional) GPIB/IEEE488, RS485, USB, and LAN.
  • SD card slot (optional).
  • Filter functions which can be adjusted for analogue interface.
  • 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).
  • Datalog function: Current operating values are saved to the memory card at adjustable time intervals.
  • Protective functions for OVP, OTP, UVP, OCP.
  • Special versions available on request.
