Ac 220v Single Phase Motor Speed Controller, Fan Motor Speed Control Switch, Temperature Control Thyristor Voltage Dimmer And RegulatorThe 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, tungsten iodine lamp, etc.), lampe conomie d'nergie, lumire LED. Caractristiques: Peut jouer la gradation, les thermostats, l'effet de pression. La sortie est connecte au electric wire or to electrical appliances, rotary potentiometer, can play speed, pressure, thermostat. Using the new bi-directional high-power thyristor, because the design maximum current can reach 20A. A good solution to the problem of overcurrent electric wire in case of cooling caused by the resistance is too small, can easily adjust the output voltage between AC0V and AC220V. Features: Input voltage: 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/4.6ounces Package Size: 90* 60 * 40mm / 3.5 * 2.4 * 1.6in Package Weight: 135g / 4.8oz Package List: 1 * voltage regulator
