Ac 220V 4000W Compact Controller Variable Voltage Speed Portable Temperature Light Voltage Adjuatable Dimmer

1: This is a high-quality, thyristor-regulated power supply that allows for easy regulation and helps control speed, temperature, voltage, and light. 2: It features a high-temperature resistant FR-4 PCB, an original imported SCR chip, fully thermally conductive aluminum fins, and precision high-voltage capacitors and resistors. 3: Independent switch control allows you to freely control the input power and cut off the power. 4: There is no lag, and it has a peak voltage absorption circuit that effectively protects the high-power thyristors. 5: The metal part of the top of the product is thickened, high-temperature resistant, and rustproof. The product is dense, cooled on five sides, does not generate heat, does not deform, and is safe.
