Product Description:

1. Product Description:

Voltage stabilizer is a device which makes the output voltage stable. Regulator with constant voltage, control circuit, and servo motor, etc.. When the input voltage or load changes, the control circuit for sampling, comparison and amplification, then drive servo motor to rotate, and the pressure regulating carbon brush position change, by automatically adjust the number of turns of the coil, so as to maintain the stability of the output voltage.

The fixed output DC regulated power source is composed of isolation transformer, bridge rectifier,large capacity filter power tube of big power modular regulating circuit,protective circuit, it can work continuously for a long time with the function of sufficient output current,small wave,high stability,reliable performance,limited over-current protection and self-recovery.

 

2. Product Characteristic:

It is available for any places that requires DC power supply as laboratory,industrial control,telecommunication,electrical maintenance,accumulator charging,electrolysis and electroplating, etc。

Q:What is the difference between the main transformer and the transformer used?
1, the so-called main transformer or (plant) with transformers are transformers, but according to their use of different names. The so-called main transformer: generally in the power plant or substation are so called, its function is for the system through the required level of power transformer; the so-called (factory) with the transformer is inside (power plant interior) Electrical equipment to provide power transformer. 2, the (plant) with the transformer power supply connected to the main transformer on the same bus, and some received another external power supply, so that when the main transformer can be maintained when the maintenance (plant) to continue to have power!
Q:80 kilowatts of electrical appliances need much transformer?
The selection of the transformer is based on the current. 80KW electrical current is 210A210 times (380 multiplied by 1.732) 138kva above the transformer can
Q:Altium designer DXP transformer in the same name how to change?
The same name is a painting of about 2-3mil radius of the solid circle, can not directly change, must be copied from the source file to the schematic library file can be changed, that is, to re-create schematic symbols.
Q:Which is good for the transformer?
and other electrical equipment. Product design novel, small size, handsome in appearance, with low loss, low noise, impact resistance and so on. Widely used in industrial and mining enterprises, textile machinery, printing and packaging, petrochemical, schools, shopping malls, elevators, post and telecommunications, medical machinery and other needs of the normal voltage guarantee occasions.
Q:How to calculate non - isolated power transformer parameters
T cycle, f frequency D minimum duty cycle Vout output voltage Vin input voltage Ton magnetizing time
Q:Production of high and low voltage switchgear transformer industry belongs to what industry category
Category C Manufacturing Electrical machinery and equipment manufacturing In the class 392 transmission and distribution and control equipment manufacturing
Q:Single-phase and three-phase transformer is what it means
Single-phase transformer, generally refers to the primary coil is a single-phase single-coil design, the secondary can have one or more winding coil, the ideal state of the secondary total power is equal to the total primary power. For example, the common primary power supply low voltage 220 volts, the core made of mouth font, Japanese font, ring, R-shaped. Three-phase transformer, the general primary three windings, the connection is divided into triangular and star, Yanbian triangle, etc., the three winding voltage phase difference between 120 degrees, which is the common three-phase 380-volt wiring, the core The traditional three-phase three-core column, three-phase five-pin column, involute and other forms. In fact, there are many substation large-scale three-phase transformer, in order to transport and installation convenience, but also for good heat dissipation, there are three separate single-phase transformer, the use of traditional triangular or star connection input, equivalent to a Three-phase transformer.
Q:Is the secondary current rating of the transformer line current or phase current?
For star-wiring products, the line current = phase current For triangular wiring products, the rated current refers to the line current (phase to phase current)
Q:50KVA transformer maximum load is how much?
Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). The circuit symbol is commonly used as the beginning of the number.
Q:Proteus transformer how to adjust the parameters, the 220V into 14V output.
2, in the Proteus simulation diagram, double-click the transformer symbol, open the transformer parameter settings dialog box, which                 Primary Inductance 1H (set: can be fixed)                 Secondary Inductance 0.00406H (set by press)
