The products are mainly used for resistive loads (such as wire, soldering iron, heater, 220V drill with brush, electric fan, blower, blower, incandescent lamp, halogen lamp, iodine lamp au tungsten, etc.), energy-saving lamp, LED light. --Zjb6MSK-SxsdPRc28W3Q3DxYTv4" alt="image host" loading="lazy"/> Features:< br/ > Can play dimming, thermostats, pressure effect. The output is connected to the electric wire or electrical appliances, rotary potentiometer, can play speed, pressure, thermostat. Using the new bi-directional high power thyristor, because the maximum design current can reach 20A. A good solution to the problem of over-current electric wire when cooling caused by the resistance is too small, can easily adjust the output voltage between AC0V and AC220V. Features: Voltage input: 220V Adjustable Voltage Range: 0-220V Maximum Power: 4000W Main Color: Silver Item Size: 85*58*38mm/3.3*2.3* 1.5in Item Weight: 130g / 4.6oz Package Size: 90 * 60 * 40mm / 3.5 * 2.4 * 1, 6 inch Package Weight: 135g / 4.8oz Package List: 1 * Voltage Regulator
