Product Description
BC1 Porcelain Plate Adjustable Resistor Overview
The BC1 series adjustable resistor, also known as a potentiometer, offers versatile connection options with dual or triple terminal configurations for precise electrical control applications.
Key Features & Benefits
- High power capacity up to 500W standard (customizable up to 2000W)
- Wide resistance range: 1Ω to 5KΩ
- Excellent humidity resistance with protective enamel coating
- Dual, triple, or quadruple potentiometer configurations available
- High-quality resistance alloy wire for stable performance and long lifespan
- Natural cooling design with robust overload capacity
Construction & Design
The BC1 rotary-type resistor features high-quality resistance alloy wire wound around a ring-shaped ceramic skeleton and fixed with high-temperature glaze. The center disk includes a rotor that drives the brush across the resistor body to achieve variable resistance values.
