Product Description This thyristor electronic voltage regulator is mainly used for resistive loads (such as incandescent lamps, LED lamps, etc.) and single-phase AC brushless motors. The adjustable voltage range is 20V-220V, suitable for low-voltage driven heavy-duty lines. Factory applications: For example, cutting foam plastic, pearl cotton, raincoats, etc., for voltage regulation and power reduction. It uses a bidirectional high-power thyristor with a current up to 40A, solving the overcurrent problem caused by excessive resistance when the heating element cools too slowly; it can easily adjust the mains output voltage, continuously adjustable from 10V-220V, without delay or hysteresis. Application examples: Temperature regulation of electric furnaces and water heaters, dimming of lamps, speed control of small motors, thermostats for electric irons, etc. Product Features: LED digital display, clear and easy-to-read data. Uses a high-precision potentiometer for voltage regulation, real-time control of voltage changes. High temperature resistant and non-deformable, made of metal, rust-proof, effectively preventing high-temperature oxidation and rust. Zero hysteresis, zero delay, with peak voltage absorption circuitry to effectively protect high-power thyristors, featuring multiple protection functions including surge protection, peak voltage protection, and RC absorption. Side-mounted heat dissipation holes ensure faster heat dissipation and safer operation.
