Introduction:
SRFII
series second generation relay type intelligent LCD display full
automatic AC voltage regulator is a brand-new concept product. It is on
the basis of years of producing relay type full automatic ac voltage
regulator, after improvement, innovation and perfection of design with
low energy consumption, over voltage and over current protection,short
circuit protection etc. And sets many new technologies such as
selective delay, impact resistant, multi function LCD display, energy
saving and environmental protection.
