TND(SVC)-3000VA High-precision single-phase AC voltage regulator for measuring equipment


♦ Summary


TND (SVC) series single-phase high accuracy full automatic AC voltage regulator is one of the leading products of our company. Their structure is composed of the contact type auto-former regulator, servo electric motor, automatic control circuit and so on. When the electrical network voltage is unstable or the load is changed, it will automatically sampling control circuit and send out the signal to drive servo electric motor, adjust the carbon brush position of auto-former regulator so as to make the output voltage to be the rated value and be the steady state.
There are lots of merits of our company's voltage regulator such as various varieties, complete specification, and beautiful appearance. And it also has characteristics of started waveform, reliable performance, long-term movement and so on, and it is equipped with the time delay, over-voltage, and under voltage protection function and can widely be used in many electricity place, is one kind of ideal voltage-stabilized source that can keep your equipment on.

♦ Principle of work


This product mainly composes of contact voltage regulator, sampling, comparison, enlarge­ment control loop, implement servo motor and so on, the entire electric circuit constituted the closed loop circuit.
When the input voltage and load are changing, carries on the sampling by the sample electric circuit to the output voltage, carries on the comparison and enlargement with the setting reference. The output signal control servo motor drives voltage regulator carbon brush tumbler rotation, thus adjust the rated voltage value of output voltage setting to guarantee the stable voltage output.
The Main Principle sees following Figure:

♦ Operating Instruction


First take out the whole machine from the packing case, good take care of the spare parts, and read (Operation Instruction Manual) carefully.
Put this machine indoor dry and ventilating place, insert the power source plug or connect the line according to this machine marking, after inspect that there is no mistake, and open the power switch of the machine, this machine works, then, observe whether the output voltmeter instructs as the corrective instruction 220V, then, turn on the using electrical equipment.
When input voltage or load are changing, the inside machine servomotor will automatically rotate to adjust the output voltage. The running sound sent out is the normal phenomenon. After using, close the electrical equipment power switch first, and then close the power switch of voltage regulator. Please do not take the power switch of voltage regulator using as the switch of all equipment. It should inspect whether in complete before starting.
When this voltage regulator is used in the place with general low electrical network voltage, it must pay attention to the using available capacity to be supposed to reduce according to the proportion, its relations sees the following Figure.
