ATP3680 Resistance decade

The compact ATP series offers with the ATP3680 a precise stepless adjustable resistor.
The resistance is precisely set via pushbuttons + (plus) and - (minus). The set value can be read conveniently via the display. An additional measuring device is not necessary.
The replaceable fuse protects the resistor decade from damage in case of overload.


  • Easy connection via 4mm safety sockets
  • Safe and reliable function
  • Compact design for industrial use
  • With built-in overload protection
  • Robust and abrasion resistant labeling


The compact ATP3680 offers a precise resistance adjustable via pushbutton. Due to the display no further measuring device is necessary to adjust the resistance.


  • in research, development, production and quality assurance
  • in long-term tests and test fields
  • for demonstration purposes
  • for use in schools and training
