power adjustable wirewound resistor (sliding rheostat) — 1pcs This Rx20t series sliding rheostat is a power, variable wirewound resistor designed as a brake/load element and adjustable resistor for testing and control. Available in multiple power and resistance options, it provides a reliable, adjustable load solution where stable dissipation and coarsetofine resistance control are required. Key benefits Precise adjustable load: Smooth sliding adjustment lets you set resistance continuously within the chosen range to tune current or voltage drop without swapping components. power handling: Offered in a wide range of power ratings (examples: 25W up to 10KW; common options include 100W, 300W, 500W, 1000W) so you can pick the power capacity that matches your application. Durable wirewound construction: Wirewound element gives stable resistance under load and good thermal endurance for extended use as a brake or load resistor. Versatile replacement/upgrade: Use as a controllable brake/load, current limiter, or bench load for equipment and prototypes. Key attributes Model: Rx20t Quantity: 1pcs Type: Adjustable variable wirewound resistor (sliding rheostat) Power ratings available: 25W 10KW (examples listed: 100W, 300W, 500W, 1000W; select per listing) Resistance range available: 1 ohm 10 kΩ (examples listed: 150Ω, 500Ω; specific options include 5Ω at 300W) Material: Wirewound resistive element (as specified) Functionality: Continuous variable resistance via sliding contact for braking, load testing, current limiting and speed control Performance: power dissipation capability and stable resistance under thermal load (dependent on selected power/resistance option) Typical applications Motor braking and speed adjustment: Use as a rheostat/brake for DC motor starting and deceleration where controlled dissipation is needed. Load testing and bench work: Simulate resistive loads for power supplies, inverters, and electronic equipment to verify behavior under different load conditions. Current limiting and tuning: Provide adjustable series resistance for prototyping, lab setups, or when limiting inrush/current is required. Ordering notes Choose the correct power rating and resistance variant for your application (examples in the title include 150R, 500 Ohm, and 300W 5 Ohm). Confirm the selected Rx20t option before installation. This listing is for 1pcs of the specified Rx20t adjustable wirewound sliding rheostat in the power and resistance option you select. If you need a robust, adjustable resistive load or a simple rheostat/brake solution, this Rx20t wirewound sliding resistor provides straightforward adjustment, durable performance, and a range of power/resistance options to fit many industrial and lab uses.
