Wire Wound Rheostats

	A Rheostat is used to raise or lower the resistance of a circuit and correspondingly to decrease or increase the current following.
	Our Rheostat are manufactured in a very wide range. which are being used in electronic industries , schools, collages laboratories over decades.
	A wide range of Rheostat are available from 0.1 amp. to 200 amp.*
	Values from 0.5 ohms to 12000 ohms.
	Customized designing available on request.
	Higher wattage resistors for special applications can be made.
	Rheostats : Open / Covered / GRADED / L.S.M.-Lead Screw Motion Range : 0.5 ohms - 12000 ohms Power : 0.1 Amp - 200 Amp * Selection Table available for Reference.
	STEAD Brand Wirewound Sliding Rheostats are spaced wound with best quality Cu/Ni or Ni/Cr Alloy Resistance Wire having very low temp. Co-efficient and wire is protected with high temp. Resistance Compound. The winding is done on vitreous enameled drawn steel tubes, fitted with aluminium die casted stands/fabricated steel stands. Phosphor Bronze or Self Lubricating Copper Graphite Contacts are fitted on brass slider, Slides on solid drawn brass rods.
