Rheostat Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12414
Jlab Export is a leading Rheostat Manufacturer,and suppliers in India
Rheostat (code EL-PL-12414) is a 50 ohm sliding rheostat: a double-contact block moves smoothly along a brass guide rod over the winding, and three insulated lock-type brass terminals connect the slider and both ends, so it works as a variable resistor or a potential divider. Its total resistance and maximum current are marked on the slider. JLab builds this rheostat at its Ambala plant in India.

Choosing Between 50 Ohm and 30 Ohm
With the same supply, the 50 ohm winding can bring the current lower than the 30 ohm model, which helps when a practical needs a wide current range. In potential-divider use, a higher-resistance winding draws less current from the supply, but its output drops further when the load resistance is low, so the lower-resistance model is often preferred for low-resistance loads.
Care of the Sliding Contact
Move the contact block along the rod without forcing it. Dust or tarnish on the winding and guide rod makes the current jump as the double contact passes over, so wipe them with a dry cloth from time to time, and tighten the brass screw if the block starts to rock. Before switching on, set the slider for maximum resistance in rheostat use, or for zero output as a divider, then bring the current up gradually.
