Rugged Construction, B Phosphor Bronze Sliding Contacts (Copper Carbon Optional), Silicon coated to prevent loosening of wire, Box type enclosures available, Choice of movements: [1] Manual Hand Sliding [2] Screw assisted wheel sliding, Rheostats for 3 Phase applications assembled, Multi tube, High capacity Rheostats can be designed as per individual requirements.

Our clients can avail from us high-grade Wire wound Rheostats, Hand Sliding Type, which are manufactured using optimum quality raw material and latest technology machines. Features: Power: – Designed with 150% of specified power dissipation to limit maximum surface temperature rise up to 200°C, at full power. (Direct derating to 67% of maximum allowable wattage).Also designed to withstand short time over load of 10 times the rated power for 5 seconds. Pitch: – Minimum winding pitch is maintained at 2 time wire diameter in order to avoid inter-turn short circuit due to failure of wire insulation. Maximum winding pitch is maintained at 3 times the wire diameter to ensure maximum utilization of surface area for heat dissipation. Joints: – Winding elements are spot welded to end brass clip terminals to ensure rigid & confirmed joints with very low contact resistance. Coating: – Rheostat is coated with high temperature silicone varnish to provide protection against extreme environmental conditions, mechanical damage and to further assist in heat dissipation. Contact Assembly: – Brush is made of copper-graphite for good electrical contact and self greasing properties to ensure smooth movement for maximum operation cycles. Further the brush is pig-tailed and spring loaded to ensure free movement with firm electric continuity. Slider Bar: – Nickel plated Brass slider for rust free, smooth movement and good electrical conduction. Slider bar is insulated from side bracket using a ceramic insulator bush and nylon lock bush for good electrical insulation properties. Brush Handle: – Slider brush handle is made of ceramic materials for good electric and heat insulation & longer life. Mounting Bracket: – Fabricated from M.S. sheet for firm holding and finish with powder coating for longer life. Wiring: High temperature withstanding Teflon covered insulating wires with crimped copper lugs to ensure good contact & longer life. Output Terminals: – Molded and colour-coded insulating terminals are provided for east of terminal identification. Red & black for fixed resistance and green for variable resistance terminal. Earthing Terminal:- Earthing tag with screw provided for proper earthing of rheostat frame.(Both side brackets are internally electrically connected with the help of mounting stud and doom nut)

SPECIFICATIONS:  RHEOSTAT COMES IN DIFFERENT RANGES:  10, 20, 30, 50, 100 etc. ·         Nichrome type, Bell terminal Continuous Constantine type. ·         Rheostat are used as series resistors or potentiometers. Open type slide wire type with a variety of resistance and current carrying capacity. Constantine wire is used as resistance.  ·         Three 4mm standard terminals are provided. One at each end of the wire and the third at one end of the slider-rod thus the Rheostat can be used as potentiometer also.  ·         Resistance in ohms and current carrying capacities are marked on it. The end support are made of Bakelite. ·         A quality product from HOVERLABS ideal for use in School Laboratories in developing countries of Asia, Africa and South America ·         Standard specifications for school laboratory use. Ideal mix of Quality and Economy.
