Key Features: Thyristor Module: the Module of the Scr Voltage Regulator Is Made of High-quality Thyristors. Sensitive, Voltage Resistant, and Highly Efficient Scrs Provide Powerful Power and Zero Hysteresis Control for the Scr Voltage Regulator. Excellent Heat Dissipation: the Scr Voltage Regulator Is Equipped with Multiple Dense Heat Dissipation Holes on Multiple Sides to Dissipate Heat in a Timely Manner. Excellent Heat Dissipation Extends the Life of the Product and Reduces the Incidence of Accidents. Silver Alloy Contacts: Our Independent Switch Uses Silver Alloy Contacts That Can Withstand Higher Currents, Which Prevents Electrical Sparks and Improves Safety. High-quality Material: Our Scr Voltage Regulator Is Made of High-quality Pp Flame-resistant Material. the Flame-resistant Pp Material with a Maximum Temperature Resistance of 750C Makes the Scr Voltage Regulator Safer and More Durable. High Safety: the Internal Copper Parts of the Scr Voltage Regulator Are Made of Thickened Phosphor Bronze Fittings, so They Can Withstand Higher Currents to Increase Their Safety. Good Contact: the Socket Adopts Upgraded Engagement Technology, Which Makes Its Bite Force Strong and Not Easy to Be Loosened by Plugging and Unplugging. a Well-contacted Socket Not Only Makes the Regulator Stable but Also Prevents Accidents. Adjust Power: Our Scr Voltage Regulator Is Equipped with a Knob That Allows Infinitely Adjustable Power. It Is Very Convenient to Change the Temperature, Light, Voltage, and Speed of Different Products by Adjusting the Power. Multiple Protection: Our Scr Voltage Regulators Are Equipped with Anti-peak Voltage, Anti-surge Current, and Rc Absorption Functions. the Multiple Protection Functions Effectively Protect High Power Scrs and Extend Their Service Life. Details: One-touch Switch: This Scr Voltage Regulator Uses a One-touch Switch, Which Is Very Convenient and Quick. You Can Start and Shut down Quickly with Just a Touch of the Switch. Double-row Hooks: the Product Is Equipped with Double-row Hooks on the Back to Enable It to Be Hung on the Wall for Use, Which Is Space-saving and Convenient. European Standard Plug: the Scr Voltage Regulator Uses a Special European Standard Plug to Match Your Outlet, Which Is Easy to Use. Thickened Power Cord: the Power Cord Is Thickened to Enhance Its Conductivity and High-temperature Resistance. a Thickened Power Cord Is Safer, so You Can Use It Without Worry. Application: It Can Be Used for Resistance Electric Tools, Power Tools, Motor Fans, Tungsten Lamps, Etc. It Can Be Used to Adjust Voltage, Speed, Wind Speed, Brightness, Etc. Specification: Material: Pp Flame Retardant Material, Copper Color: Black Product Model: St-bta41*B Adjustment Method: Knob Input Voltage: Ac220v Output Voltage: 0-220v Adjustable Peak Power: 4000w Maximum Load Power: 2000w Regulating Range: 0-220v (with Load Conditions, Step down to 0v, Step up from 10v) Rated Current: 9a Peak Voltage: 18a Product Size: 10*10*5cm/3.93*3.93*1.96in Package Size: 14.5*12*11.5cm/5.7*4.72*4.52in Gross Weight: 0.5kg/1.10lbs Package Included: 1*Scr Voltage Regulator 1*Chinese Manual Notes: 1. Measuring the Output Voltage When Empty Is a Virtual Voltage, You Have to Connect a Load of 20w or More to Measure the Correct Output Voltage. 2. Input Ac Power, the Output Is Also Ac Power, Not Dc Power. 3. 4000 Watts of Peak Power Is the Limit Power When Working with a Resistive Load. with Inductive Load Is 1/3 of the Resistive Load. the Resistive Load Is a Tungsten Lamp, Heating Wire, Etc. the Inductive Load Is a Series Excitation Motor, Etc. Be Careful with Electronic Products with Circuit Boards. 4. Products That Do Not Support Buck Products Do Not Apply to This Product, Such As Household Water Pumps, Single-phase Motors, Household Microwave Ovens, Smart Rice Cookers, Led Energy-saving Lamps, Etc. 5.
