Wire-wound potentiometers series DP

Construction and execution

Our wire-wound potentiometer series DP3 consist of a resistor carrier with a winding made of CuNi, which is joined with the connections over a pressure contact. The connection of the slider is made with a special spring. The potentiometer series DP20 up to DP300 consist of a steatite rinf with a winding made of special wire and oxidation free end tabs. The winding is coated with a layer of inorganic cement. The connection of the copper-graphit or precious metal slider is made with a special spring.

Features

  • Power range: Single potentiometer 3 W up to 300 W
  • High operation reliability
  • Longlife device

Application fields

There are various application fields in electro-technics and electronics.
