INTRODUCTION:
This cursor rheostat though a variable wire-wound resistor to change the current intensity of a circuit. They can be served as a variable resistor or a potentiometer.
-
Widely used in teaching experiments.
-
Withstand over-load in a short-term.
-
The structure of metalic armature improve the reliability of the circuit, and play a good cooling effect. Closely coiled resistance wire used a special cement to fix on a ceramic pipe.
-
This rheostat used 4mm security sockets as terminals.
SPECIFICATIONS:
-
Allowed resistance error: rated resistance ± 10%
-
The maximun voltage: 600V
-
Bandwidth: 0-20kHz at 3dB
-
The structure is according to the CEI1010-CAT III -250V eff-pol 2 standard
-
Metal covering
CONNECTION:
The cursor rheostat can be served as:
1. Variable resistor
-
The terminals are userd A (black) and C (red) or B (black) and C (red).
-
Cursor's movement shows the resistance's chenging.
2. Potentiometer
-
Take A (black) and B (black) as two terminals. Take C (red) as a branch for output.
