  • High Speed Programming

    A 10 to 20 times higher programming speed and lower output capacitance. Excellent for laser applications, fast test systems or as current source with low parallel capacitance as used in plasma chambers. For more information download the data sheet High Speed Programming.

  • Front Power Output

    Binding posts at the front panel instead of at the rear panel (n/a for SM7.5-80). For more information download the data sheet SM800 series (see pages 1-2, 1-5 & 1-6).

  • Digital Voltage and Current Setting

    Reliable, long life digital encoders are implemented at the front panel. Includes total front panel lock and a coarse or fine pitch adjustment depending on the turning speed. For more information download the data sheet Digital Encoders.

  • 19-inch Rack Adapter

    Rack adapter sets for positioning SM800 units in a 19-inch rack. For more information download the data sheet SM800 series (see pages 1-5 & 1-6).

      • RA19-1SM800 — for 1 unit
      • RA19-2SM800 — for 2 units side by side
      • RA19-1SM800-FPC —  for 1 unit with front panel connection
      • RA19-2SM800-FPC — for 2 units with front panel connection
      • RA19-SM800-ES150 — for 1 unit SM800 and 1 unit ES150 side by side
  • Increased Output Power

    For conservatively rated units extra output power (with the same reliability) is allowed. At some derating, either the maximum output voltage or current of these units can be increased by about 10%. Contact us or our local distributor for information which units extra output power is allowed.

  • 2-Quadrant Output: Power Sink

    The 2-quadrant operation maintains the output voltage constant regardless the output power is positive or negative. Ideal for PWM-speed controlled DC-motors and ATE-systems. For more information download the data sheet Power sink.


  • Sequencer

    Arbitrary Waveform generator or standalone automation. The sequencer is integrated in the Ethernet controller. For more information download the data sheet Ethernet Interface.

  • Secured Voltage and Current Setting

    For maximum security the settings for CV and CC can be adjusted with a screwdriver only and are protected with a plastic cap from accidental adjusting. Units with digital voltage and current setting already have secured settings.
