TND2 series single phase automatic AC stabilizer is the second generation product developed by our company. It is composed of contact voltage regulator, automatic control circuit for sampling, amplification, controlling servo motor to drive arm, brush to turn in the required direction, so that the output voltage is adjusted to the rated value to achieve voltage regulation. The stabilizer panel is displayed in LED Chinese, with delay output, overvoltage, undervoltage protection, and load analog display and overload alarm. The exterior is beautiful and generous, small in size and thin in thickness, light in weight, low in self-consumption, stable and reliable, small in output waveform distortion. It can be widely used in industrial production, scientific research, medical and health care, household appliances and other areas with large power grid voltage fluctuations or seasonal power grid voltage fluctuations, and can provide high-quality power supply for loads.
This manual describes the TND2 series high‑accuracy, fully‑automatic single‑phase AC voltage regulator developed by JW. It outlines the scope, model designations, operating and installation requirements, main technical parameters, physical dimensions, and ordering information.
The regulator features digital display, delayed output, over‑/under‑voltage protection, load simulation, overload alarm, high efficiency (>90%), low distortion, and compact construction suitable for industrial, scientific, medical, and household applications where grid voltage fluctuates. This manual is written in Chinese.
