If you are looking for a motor controller, then your research is over here. That's because our product can meet your need. Adopted of premium material, practical and durable for long time use, not to get deformed and bring you much -Color:As Shown-Material:Aluminum alloy, PCB, stainless steel-Size:8.50X5.50X3.80cm/3.34X2.16X1.49inWorking voltage: AC 220VAdjustable voltage: AC 10-220VEfficiency: over 90%Maximum power: 4000W (resistive load limit power)Knob inner hole diameter: 6mm- Adapt to more DC motors, and can provide sufficient driving capacity for the motor. The standard 35A 4-position terminal is used, so that it can provide 4000W power.- Using temperature resistant circuit board, the circuit design is reasonable, and the design of the welding circuit is enlarged and thickened, which is enough to deal with even a large current. Safer and more reliable to use.- capacitors with metal film capacitors can effectively absorb surges and voltage spikes, protect silicon controlled more effectively, and use them more efficiently.- Note that the load must be connected before voltage regulation. Thyristors are mainly used for resistive loads (heating wire incandescent lamps, etc.), and most single-phase AC motors can also be used, but there is no that they can be used.- Characterized by a sturdy and reliable texture, not to break, serving you for a long time. list: 1 x Motor Controller list: 1 x Motor Controller
