Product features: zero lag, zero delay, with peak voltageabsorption circuit, effective protection of high-power thyristor anti-surge, anti-spike, RC absorption multiple protection.
Name: SCR electronic voltage regulator
Model : DTY-4000W
Voltage : AC220V
Output voltage: 10-220V(The voltmeter does not work whenthe output voltage is lower than 5V
Rated current : 15
The speed of the power tool is too fast,the temperature of the electric furnace wire is too highand the light bulb is too bright.
● Select Zhengxi Motor Speed Controller Can adjust speed, temperature, light.
● 15A Current overload protection switch, real-time monitoring is safer!
● Automatic overload protection design, monitor electricity safety at any time, 24-hour power guard!
● Replace traditional products Function two in one


Regulating from 10V
● LV adjustment is more practical
● Built-in trigger module to achieve 10V starting,the lower the starting voltage, the easier it is to use

High-quality thyristorprecise voltage regulation
● New two-way high-power thyristor,
current up to 40 amperes

Display voltageIn order to accurately adjust
● The new LED matte screen, the digital display is clear,not dazzling!

International standard socketNo need to worry about wiring
● The product is equipped with a national standardfive-hole socket and a 1.2-meter power cord


1.The measured output voltage during idle operation is a virtual voltage, and a load of over 20W mube connected to measure the correct output voltage.
2.Input AC power, output is also AC power, not DC power.
3.The aforementioned 3000W refers to the ultimate power when working under resistive loads, withinductive loads accounting for one-third ofresistive loads,Resistive load refers to tungsten filament lamps, heating wires, etc., while inductive load refers toseries excited motors, etc., including circuit board electronic productsUse with caution.
4.The metal shell of this product must be securely grounded.
Household appliances, industrial appliances,scientific experimental instruments, factories, school electrical equipment, etcNote: the load must be connected first, then Commissioning voltage (test voltage)
