The D series economical three-phase intelligent power regulator combines the precise control of the power regulator with the economic applicability of the phase shift voltage regulator module. It is manufactured using digital design, high-quality components, and the latest microcomputer control technology, with outstanding functions. It can be adjusted automatically or manually to change the voltage on the load, thereby adjusting the output power. Realize stepless adjustment of load voltage from 0 to full grid voltage. Internal integration of powerful software modules
Widely used in electric heating power control, melt blown cloth equipment heating constant temperature control, transformer primary voltage regulation, variable resistance load, lighting regulation, and other occasions.
