1pcs Power Adjustable Variable Wirewound Resistor — Sliding Rheostat Brake Load (Rx20t) Key benefits Wide power and resistance coverage: select from a full range of power wirewound resistors (25W 10KW) to suit lowpower bench work or large brake/load applications. Precise, continuous adjustment: sliding rheostat construction provides smooth, onthefly control of resistance and current for testing, braking and tuning. Robust heathandling: wirewound design is built to dissipate power reliably in load applications, reducing the risk of overheating under rated conditions. Versatile selection: common options include 100W, 500W and 1000W models; special reference models include 150R, 500 Ohm and 1000W 50 Oh (Rx20t). What this product is An adjustable, power wirewound resistor sold as 1pcs. Functions as a sliding rheostat for variable resistance control, suitable as a brake load or adjustable load in electrical circuits. Available resistance range: 1R 10K R (1 ohm to 10 kiloohm), with specific nominal values referenced in the product title (150R, 500 Ohm, 50 Oh for 1000W model). Power rating options span from small 25W units up to heavyduty 10KW units; commonly used power ratings noted: 100W, 500W, 1000W. Key attributes Type: Adjustable variable wirewound resistor (sliding rheostat / brake load). Power ratings: 25W 10KW (includes 100W, 500W, 1000W and more). Resistance range: 1R 10K R (examples: 150R, 500 Ohm; 1000W 50 Oh available). Quantity: 1pcs per . Model reference: Rx20t. Primary use: variable resistance for braking, load testing and current control. How it solves common problems Replaces fixed resistors when variable control is required: dial in just the right resistance to control motor deceleration or simulate varying load conditions. Simplifies load testing: use the resistor as a controllable load to safely soak test power supplies, alternators or battery outputs without changing discrete resistors. Protects equipment during startup and adjustment: by limiting inrush current and allowing gradual adjustments, it helps prevent component stress during commissioning or tuning. Typical applications / use cases Motor braking and speed control: add the unit across a DC motor to create a variable braking load for tuning deceleration and stopping characteristics. Load testing and bench work: use as an adjustable load for power supply testing, battery discharge experiments or component burnin procedures. Current limiting and tuning circuits: temporarily insert as a variable series resistor to limit current during setup, troubleshooting or gradual rampup procedures. Usage notes and selection guidance Choose the power rating and resistance value that match the maximum power dissipation and current expected in your application. The product line covers from 25W up to 10KW and resistances from 1 ohm to 10 kiloohm to accommodate diverse needs. The sliding contact provides continuous adjustment; ensure connections are secure and rated for the selected current to maintain safe operation. For heavyduty or prolonged power use, confirm adequate cooling and mounting per your system requirements.
