Product Description:

1. Product Description:

Drive Variable-frequency (VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor power frequency mode to control AC motor power control equipment. Inverter is mainly composed of rectifier (AC inverter), filter, inverter (DC AC), brake unit, driving unit, detection unit, and so on. The inverter by the internal IGBT to adjust the output voltage and frequency, according to the actual needs of the motor to provide the power supply voltage, and then to achieve energy saving, speed control purposes, in addition, there are a lot of converter protection functions, such as over current, over voltage, overload protection, etc.. With the continuous improvement of the degree of industrial automation, frequency converter has been widely used.


2. Product Characteristic:

1 Frequency conversion energy saving. Motor use frequency converter is to speed, and reduce the starting current.

2 Power factor compensation energy saving. No power will not only increase the power loss and equipment of fever, more important is power factor lower leads to a decrease in power grid

3 Soft start energy saving. After the use of frequency conversion energy saving device, the use of inverter soft start function will enable the starting current from zero, the maximum value is not more than the rated current, reducing the impact on the grid and the power supply capacity of the requirements, and extend the service life of the valve. Save the maintenance cost of equipment

Q:Transformer issues?
Damn, had to read the question before I realized it has NOTHING to do with Optimus Prime or Megatron. (*laughing*)
Q:Transformer is the transmission of electrical equipment
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.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on. Transformer consists of iron core (or core) and coil, the coil has two or more than the winding, which connected to the power supply winding called the primary coil, the rest of the winding called secondary coil. It can transform AC voltage, current and impedance. The simplest core transformer consists of a soft magnetic material made of iron core and set on the core of the two turns ranging from the composition of the coil,
Q:Transformer confusion.?
You are confusing VA (power ratings) with transformer ratios 120/16 7.5 :1 3300/120 27.5 : 1 So connect 7Vrms to 16 input to give output 1 52.5V Now connect this 120 (52.5V) output to the 120V input of the 120/3300 transformer The output should be approx 52.5 x 27.5 1444 Volts Use the 16/120 to step up and then the 120/3300 to step up again Take the function generator voltage to its lowest and measure at all points now gradually increase the generator voltage measuring at all points until you get what you want If the voltages are not as you expect then the VA ratings may be a problem Remember to be extra careful with High Voltages
Q:Electric transformer winding calculation.?
Basically, the ratio of voltages is the same as the ratio of turns. The currents are the inverse ratio but that kind of takes care of itself if you just deal with the voltage ratio.
Q:How to check watts of a voltage transformer?
Watts is the volts x amps. You will know the supply voltage and you can use an amp meter to find out the amps. For example 230V x 3A is 690 Watts.
Q:why are power transformers rated by KVA(kilovolt- ampere) instead of kilowatts?
Mick Johnson and Mike Roberts asked the same question. You should see their answers side by side.
Q:What is the meaning of the Y D11 on the transformer?
Transformer Y / D11 Y ----- primary side connection, star type, D secondary side connection, triangle 11 is the primary and secondary side of the phase difference of the side line voltage lag secondary side 330 degrees (or lead 30 degrees).
Q:TransFormers Or Spider-Man 3 the best summer movie?
Between those two , Transformers.
Q:Transformer capacity unit KVA?
The rated value of the output capacity of the transformer in the rated state is expressed in kilowatts (kVA) (VA and MVA are not commonly used). Since the transformer has a high operating efficiency, the original, secondary winding (winding deformation Tester) rated capacity equal to the design value. KV.A is the capacity of the transformer, KVA is the apparent power, its size and power factor. KV and KVA conversion relationship 1 kV (kV) = 1000 V (V) 1 V (V) = 1000 mV (mV) Kilovolts greater than volts greater than millivolts, the rate of 1000. 1 V (V) = 1000000 VV (μv) 1 MV (MV) = 1000000 V (V)
Q:250KVA transformer maximum load how much KW power?
250KVA transformer, the maximum capacity to load how much KW power? This is a bit of a problem, it is difficult to correct answer. Is it possible to ask how much the maximum load of the 250KVA transformer is KW? Or, how much amperes the maximum output current? If you ask, then answer you, the maximum output current is about 250 × 1.445 ≈ 361A or so
