BC1 500W Power Rotary Rheostat — WireWound Disc, Adjustable, Max R = 100 Ω A power, rotary variable wirewound resistor engineered for applications that require reliable, adjustable resistance up to 100 ohms while dissipating significant power. The BC1 500W rheostat combines robust wirewound construction with a discshaped form factor and a simple rotary adjustment for coarsetomedium tuning of current or voltage in heavyduty circuits. Key benefits power handling: 500 W rating allows use in demanding loadcontrol and test applications where lowerpower potentiometers or resistors would overheat. Wide adjustable range: Variable resistance up to a maximum of 100 ohm gives flexibility for many circuit adjustments and load simulations. Durable construction: Wirewound element provides stable resistance under current and thermal stress compared with lowpower film or carbon types. Easy control: Rotary adjustment provides intuitive, continuous change of resistance for tuning and experimentation. Spaceconscious form: Discshaped design is convenient for panel or chassis mounting where a compact, sturdy resistor is required. Key attributes Model: BC1 Power rating: 500 W Maximum resistance: 100 ohm Type: Rotary variable rheostat Element: Wirewound Shape: Disc Adjustment: Manual rotary Typical applications (examples) Motor and heater control: Coarse speed or power adjustments for small motors and resistive heating elements during setup, testing, or tasks. Bench load and circuit testing: Simulate loads and vary current draw in powersupply and component testing where dissipation is needed. Lighting and industrial dimming: Manual dimming or power reduction for wattage incandescent or resistive lighting during maintenance or development. Installation and use notes Operate the rheostat within its 500 W and 100 Ω limits to avoid overheating or damage. Provide adequate ventilation or heat sinking as required by your installation and duty cycle; power dissipation generates substantial heat. Suitable for applications that accept a wirewound rotary rheostat; ensure mechanical mounting and electrical connections match your chassis or panel layout. The BC1 500W rotary variable wirewound resistor is a practical choice when you need a simple, durable, power adjustable resistance with a discshaped footprint and up to 100 ohm range.
