<p>This is a kind of high quality and high power stepless regulation SCR voltage regulator, which can adjust speed, temperature, voltage and light. Adopts high temperature resistant FR-4 PCB board, imported original SCR chip, aluminum thermal fin, precision resistor with high voltage capacitor. No carryover and no delay, with peak voltage absorption circuit, can effectively protect the high power SCR. You can try it.</p> <p>Features:</p> <p>1. Mini size, portable and lightweight, strong power, easy to use.</p> <p>2. High power stepless regulation SCR voltage regulator, which can adjust speed, temperature, voltage and light.</p> <p>3. Adopts high temperature resistant FR-4 PCB, imported original SCR chip, aluminum thermal fin, precision resistor with high voltage capacitor.</p> <p>4. No carryover and no delay, with peak voltage absorption circuit, can effectively protect high power SCR.</p> <p>5. Anti-surge, anti-spike, RC absorb and multiple protection.</p> <p>6. External insulation flame retardant, high temperature resistant, rustproof, anti-high pressure and very durable.</p> <p>7. Adopts multifunctional industrial sockets, thick copper parts, with fine and safe contact.</p> <p>8. The installation hole design is humanized, you can decide by yourself whether you want to keep it flat or hang it.</p> <p>9. Quiet work, energy saving, stable anti-noise, and wide range of use.</p> <p>10. Suitable for water heaters, tungsten lamps, small motors, electric irons, etc.</p> <p>Notes:</p> <p>1. When measuring the output voltage when it is no-load, it is a virtual voltage. It must be connected to a load of 20W or more to measure the correct output voltage.</p> <p>2. The input is AC, the output is also AC, not DC.</p> <p>3. The 4000W mentioned above refers to the ultimate power when the device is working under a resistive load.</p> <p>4. The inductive load is 1/3 of the resistive load. Resistive load means the inductive load such as a tungsten filament lamp or heating wire, a series-excited motor, etc.</p> <p>5. This product is a metal case and must be safely grounded.</p> <p>Specifications:</p> <p></p> <p>Name: SCR Voltage Regulator</p> <p>Material: Aluminum</p> <p>Color: Gray</p> <p>Input Voltage: AC 220V</p> <p>Output Voltage: 0-220V</p> <p>Maximum Power: 4000W</p> <p>Voltage Adjustment Range: 0-220V</p> <p>Rated Current: 9A</p> <p>Maximum Current: 18A</p> <p>Main Machine Size: 100 * 83 * 75mm / 3.94 * 3.27 * 2.95in</p> <p>Item Weight: 418g / 0.92lb</p> <p>Package Size: 145 * 85 * 105mm / 5.71 * 3.35 * 4.13in</p> <p>Package Weight: 450g / 0.99lb</p> <p></p> <p>Package List:</p> <p></p> <p>1 * SCR Voltage Regulator</p> <p></p>
