Description
MV1957, MV1959, MV1963 Rheostats there each rheostat is enclosed in a robust metal case.
The back, bottom and top of the case are perforated to provide optimum cooling. 2 glass fuses protect the resistor agains excessive current and incorrect connection.
A scale with 100 scale divisions shows the resistance setting. A front panel of yellow painted steel with black screen painted symbols simplifies series and potentiometer connection.
Constructional features
The insulation is of high class ceramic material.
The resistance wire used is of highest quality with very good linearity.
Large flat brush with a sliding contact of copper graphite with specially balanced mounting guarantees perfect contact with negligible wear on the resistance.
