Application
TND/TNS(SVC) series full-automatic AC voltage regulator collects sample and amplifies it and automatically control circuit, and drives the servomotor to rotate the rocker arm and brush in required direction, and finally adjusts the output voltage to the rated value, finally reaches the aim of stabilizing the voltage. It can be widely used in areas, where the mains voltage often comes across sharp fluctuation or sharp seasonal variation, such as industrial production, scientific research medical treatment & hygiene, household electrical appliances, it can provide any loads with excellent power supply.

Technical characteristics
Output capacity
The relation between output capacity and input voltage refer to as fig. 1 When input voltage less than 198V, the output capacity of product will decrease, the working capacity of stabilizer shall come down; when you choose output voltage of 110V, the out put capacity shall be not more than 50% rated capacity,to prevent overload.
Overload capacity
The stabilizer is not allowed for working overloading long time, when the input phase voltage fluctuate within 198V ~ 250V (line voltage from 342V ~ 430V), at emergent case, it is allowed to work as specified
