500W BC1 Power Rheostat — Rotary Variable WireWound Resistor (Disc Shape), Adjustable, Max R = 1K ohm Key benefits power capacity: 500W rating lets you handle heavyduty loads and dissipate significant heat without immediate overload. Wide, continuous control: Rotary variable adjustment provides smooth, stepless control of resistance up to the maximum of 1K ohm for precise tuning. Stable, reliable construction: Wirewound design offers predictable resistance behavior and longterm stability under load. Compact disc shape: Spaceefficient form factor that fits into many equipment layouts where a lowprofile adjustable resistor is needed. What this component does and why you need it Provides a simple, robust way to vary circuit resistance continuously from near zero up to 1,000 ohms while handling power. This solves common needs for load control, testing, and adjustment where fixed resistors or less robust potentiometers would not suffice. The BC1 model is intended for applications requiring both dissipation and adjustable resistance in a discshaped, rotarycontrolled package. Key attributes Model: BC1 power rheostat Power rating: 500W Maximum resistance: 1K ohm (1000 Ω) Type: Rotary variable wirewound resistor Shape: Disc Adjustment: Rotary, stepless control Construction: Wirewound for thermal stability and consistent resistance under load Functionality and compatibility Functions as an adjustable resistive element for power circuits, test benches, and equipment adjustments where a power variable resistor is required. Compatible with systems and setups that can accommodate a rotary, discshaped wirewound rheostat rated at 500W and up to 1K ohm. Verify that the rest of the circuit (connectors, wiring, mounting, ventilation) supports the component's power dissipation. Do not exceed the specified 500W rating. Performance notes Designed for heavyduty use where sustained power dissipation is required. Wirewound construction helps maintain performance and repeatability under load. The rotary adjustment allows fine control across the resistance range. Typical use cases Motor and heater control: Provide adjustable resistance for controlling current to small motors or heating elements during setup, testing, or lowcost control situations where variable resistance is appropriate. Load testing and calibration: Act as a resistive load for power supplies and generators during functional tests, adjustments, or burnin procedures that require a power, variable load. Workshop and laboratory adjustments: Use as a durable, adjustable element in experimental circuits or equipment prototypes that need repeatable, power resistance tuning. Practical considerations Observe proper mounting and ventilation to allow heat dissipation consistent with the 500W rating. Ensure wiring and connectors are rated for the currents expected in your application and that the rheostat's maximum resistance (1K ohm) and power rating match your circuit requirements. For safety and reliable operation, do not exceed the specified 500W power rating or the 1K ohm maximum resistance. This BC1 500W rotary variable wirewound rheostat (disc shape) delivers power, adjustable resistance up to 1K ohm for demanding electrical control, testing, and adjustment tasks.
