Product Description
BC1 Variable Resistor Overview
The BC1 series adjustable resistor, also known as a porcelain disk resistor or sliding wire resistor, offers versatile functionality as either a two-terminal resistor or three-terminal potentiometer. This high-power component features multiple resistance values on a single unit with exceptional durability and performance.
Key Features
High power capacity up to 1500W standard (customizable to 2000W)
Excellent humidity resistance and wide resistance range (1Ω-5KΩ)
Multiple resistance winding wires on single unit for varied resistance values
High-quality resistance alloy wires wound on C-type ceramic ring
Non-flammable resin coating for enhanced safety and durability
Manual rotary arm operation with natural cooling
High overload capacity and resistance accuracy
Construction Details
The BC1 rotor-type barrier resistor features alloy resistance wire wound around a ring-shaped ceramic skeleton and fixed with high-temperature glaze. The disk center contains a rotor that drives the brush across the resistor body to achieve variable resistance values.
Power and Configuration Options
Available in various configurations including dual potentiometer, three potentiometer, and four potentiometer designs. Custom configurations available upon request.
