220V SCR voltage regulator – 4000W – for motors, fans and lighting – stepless adjustment – robust housing

SCR Voltage Regulator: Uses high-performance SCR as its internal chip.

.

【Quality】 Uses high-performance CR as its internal chip. Thick metal casing, high-temperature resistant and durable.

.

Perfect Performance - Continuously adjustable voltage via rotary knob. Zero hysteresis, zero delay, fast response. The measured output voltage is a virtual voltage when there is no load.

.

Note: The 4000W mentioned above refers to the maximum power when operating under a resistive load. The power under an inductive load is 1/3 of the resistive load. It must be connected to a load of 20W or more to measure the correct output voltage. The output is AC, not DC.

This product has a metal casing and must be properly grounded. 【GUARANTEE】If you have any problems, you can contact us; our customer service will resolve any issues for you. Customer satisfaction is our priority.
