Feature: 1. LED digital display, clear and convenient to view the data. 2. High accurate potentiometer is used for voltage regulation, real time voltage regulation is under control. 3. High temperature retardant without deformation, metal material, rust-proof, effectively prevents high temperature and oxidation and rust. 4. 0 lag, 0 delay, with peakvoltage absorption circuit effectively protect high power Thyristor antisurge, antipeak, RCabsorption multiple protections. 5. With side holes for quick heat dissipation. Safer in use. 6. l2wt-NaN Specification: The thyristor electronic voltage regulator is mainly used for resistive loads (incendescent filament, LED lamps,etc.), monophase A-C brushless motor, adjustable pressure range from 20Volt-220Volt, suitable for low voltage drive heaying wire. Factory use: such as cuttings tyrofoam, pearl cotton, raincoats, make it to adjust the voltage, reduce power and so on. With the bi-direcyional high-power thyristor, the current is up to 40amps, which solves the over-current problem caused by the electric resistance of the electric furnace wire when coolingis too small; it can easily adjust the output voltage of the mains at 10Volt-continuously adjustable between 220Volt, 0 delay, 0 hysteresis. Use case: Heat regulation of electric stoves and water heater, dimming of lamp and lantern, small motor speed adjustment, electric iron thermostat and so on.
