Starting Rheostat For DC Machine With 220V Coil Electrical Lab Equipment Technical Training Equipment

TB-20230203R-004 Starting Rheostat For DC Machine With 220V Coil Electrical Lab Equipment Technical Training Equipment

 

Equipment introduction

1.1 Overview

This hanging box includes 50W/2KΩ adjustable resistor, fuse and K4 safety terminal. It can be used as an armature rheostat for a DC separate excitation motor of about 180W. When the DC motor starts, the resistance in series in the armature circuit takes a larger value to limit the starting current. Equipped with a fuse to protect the circuit in case of overload. It is suitable for the teaching and skills training assessment of related majors in higher vocational schools, colleges, secondary vocational schools and technical schools.

1.2 Features

(1) The experimental device is in the form of a hanging box, which is simple and elegant overall.

(2) The size of the resistance can be set, and the operation is convenient.

(3) Equipped with safety terminals, safe and reliable.

(4) Equipped with a fuse to protect the circuit
