Model Number:Rosilesivgws0xrtg9 Product Dimensions:8 x 7 x 6 cm; 200 Grams Power / Wattage:6000 watts Item Weight:200 g Specification: SCR Model: BTA41600B Max. Power: 6000W (max. power for resistive load. For long time use, please keep it in 3000W) Efficiency: >90% Working Voltage: AC 220V Adjusting Voltage: AC 0~220V (for resistive load, the voltage may not be 0V at first, you can turn it back to 0V) Size: 130*60*47mm / 5.1*2.4*1.9in Weight: 195g / 6.9oz (approx.) Package list: 1 * Voltage Controller Note: Please connect to load first, then adjust voltage. Designed with large heat sink for better heat dissipation. The voltage regulator could control light brightness, speed, temperature. Convenient to use, simple connection and rotate knob to control voltage. This is a easy-to use voltage regulator for controlling light brightness or speed. Widely used for resistance load such as heating wire, filament lamp and most(not all) single-phase AC motors.
