Versatile voltage regulator with adjustable output for heating, lighting, and small machinery Key benefits Wide compatibility: suitable for electric heaters, water heaters, lamp dimmers, small motor speed controllers, welding temperature controllers, and related equipment. Durable protection: builtin peak voltage absorption circuit protects power silicon, helping to extend service life and improve reliability. Flexible control range: output voltage easily adjustable from 50 V to 220 V to match different loads. Easy to use: install in series with a desk lamp or other equipment; the rotating knob provides control for brightness, speed, pressure, and temperature as needed. What it does Allows adjustable control of voltage for a variety of devices, enabling finer performance and safer operation. Provides a simple series connection method so you can integrate it with existing lamps or equipment without complex wiring. The knobbased control supports multiple functions depending on the connected load, including brightness adjustment for lighting, speed regulation for small motors, pressure regulation, and temperature adjustment for heating devices. Specifications and compatibility Applicable devices include electric heaters, water heaters, lamp dimmers, small motor speed controllers, and welding temperature controllers. Output voltage range: 50 V to 220 V. Control method: series connection with the load; manual adjustment via rotating knob. Design feature: peak voltage absorption circuit for protection of power silicon. Usage scenarios Scenario 1: Dimming and adjusting brightness for desk lamps or compatible lighting to achieve desired ambiance or working conditions. Scenario 2: Regulating the speed of small motors in hobby projects, small appliances, or other devices requiring variable speed control. Scenario 3: Temperature or heating regulation for electric heaters, water heaters, or welding temperature controller applications, enabling gradual warming or controlled thermal profiles. Installation notes Connect the regulator in series with the target equipment or lamp. Use the rotating knob to set the desired brightness, speed, pressure, or temperature based on the connected load. Ensure input and output voltage are within the specified range (50 V to 220 V) and follow standard safety practices for electrical work.
