TND1(SVC) Single phase Automatic Voltage Regulator

General

Application: TND/TNS(SVC) series full-automatic AC voltage regulator collects sample and amplifies it and automatically control circuit, and drives the servo motor 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.

Features: Elegant appearance, compact structure, light weight, low power waste, complete protection functions, stable and reliable, low output waveform distortion and so on.

Technical characteristics

Output capacity

The relation between output capacity and input voltage refer to as fig.1

When input voltage less than 198V,the out put capacity of product will decrease, the working capacity of stabilizer shall come down; when you choose output voltage of 110V, the output 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 in sheet 1.

Selection Notice

1.Input and output of three-phase products of this series are of three-phase four-wire connected, please wire them with neutral line before using.

2.When the three-phase voltage regulator is applied to single-phase or three-phase, max capacity of each phase should be one third of rated capacity.

3.When the input phase voltage is lower than 198V,the output capacity of voltage regulator will be reduced, then the loads should be reduced correspondingly ,otherwise, it may be overloaded; when the output voltage is 110V,then the output capacity should not be beyond 50% of rated capacity, otherwise, it maybe overloaded. Please refer to fig.1 for detail characters.

Sheet 1 Safe consult coefficient of choosing regulator capacity

Load Kind	Consumer samples	Safe coefficient	Chosen capacity rate
Complete resistive loads	Incandescent lamp, resistant coil, electric cooker	1.1 ~ 1.3	>1.1 - 1.3 times of total rated capacity
Inductive, capacitive loads	Fluorescent lamp, fan, pump, air-conditioner, refrigerator and etc.	2.5 ~ 3	>2.5 - 3 times of total rated capacity
