Introduction of SVF-G7 Series High-performance Vector General-purpose Frequency Inverter

 

1. Voltage class: 380V

 

2. Range of power: 0.4KW~450KW

 

3. Stable and reliable Control Mode

 

General

 

 SVF-G7 series VFD communicate with PC, PLC etc upper machines, and they need the support of standard expansion cards SC-EXT1-IO. And the cards supply RS485 communication interface. Between the upper user machine and frequency inverter communicate through the international standard ModBus communication, and the upper user machine as host machine, and the frequency inverter as slave machine. The communication content could be finished as follows: send operating command to frequency inverter, setting operating frequency, changing function code parameters, reading frequency inverter operation situation, monitoring parameters, fault information, function code etc.

AC Driver  Variable Frequency Drive for 3 Phase

 

Q:What are the AC motor speed control methods? What are the characteristics of each
1, the frequency converter: smooth, according to the need to adjust the speed, is the future direction of the development of AC motor; (FM) 2, star, triangular connection conversion, generally in the larger motor start star start, triangular operation, Starting current. (Magnetic pole pairs) 3, there is a two-speed, three-speed motor, an increase of the winding, the main change in the stator winding connection to change the speed. (Change the number of pole pairs) The speed of change has two factors: magnetic pole logarithm, frequency
Q:Will the asynchronous motor pole change the number of speed control can also be combined with the frequency converter
Of course, because the factors that determine the speed of asynchronous motor power supply voltage, frequency and motor pole pairs, so asynchronous motor speed can be achieved by changing the number of magnetic pole pairs, but this method needs to make a greater motor changes, Trouble, and change the number of poles can only achieve a single speed change;
Q:Oil-free vertical vacuum pump why a little negative pressure inverter on the torque limit
Here is not the inverter can solve the problem, you should first 220V single-phase AC rectifier for the DC (full-wave rectifier plus filter about 310 volts),
Q:What is the application of variable frequency speed control?
Generally used in the need for continuous speed control of the place. With the general exchange of motor than its advantages is able to continuously speed. DC motor, although also continuous speed control, but the price is expensive, the volume weight is too large.
Q:In the official website to buy ThinkPad notebook, to the power adapter?
Where the power adapter to buy the general will be supporting
Q:How to disassemble the notebook power adapter
. 2, the power adapter on the side of the lateral side of the white paper, with an electric knife blade along the power adapter under the cover between the gap cut, and then hit the electric knife knife with a hammer, so that the electric knife from the adapter between the upper and lower cover cut into. In the different positions of the gap between the upper and lower covers of the adapter, use the tip of the electric knife to be scratched along the gap. When the upper and lower covers are first split, the depth of the tool is deep and then the upper and lower covers of the adapter are separated
Q:Delta VFD-A frequency converter motor number of poles set
Variable frequency Drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly rectified (AC variable DC), filter Wave, inverter (DC variable AC), the braking unit, the drive unit, the detection unit micro-processing unit and so on. The inverter is used to adjust the voltage and frequency of the output power by breaking the internal IGBT.
Q:Three sets of batteries (540V) DC power supply U / f inverter.
This is the reason for the battery characteristics, your group of easy to burn the battery discharge characteristics of the curve should not be partial to engage, so easy to burn. Ultimately it is your group of battery quality is relatively poor!
Q:Is the laptop power adapter hot?
Third, the power of the nominal voltage than my books the battery voltage is much higher, not an accident, right? First of all, to know is that the power supply to the books and the battery power supply to the notebook is different. Battery-powered, the battery output is pure DC, very clean, the battery voltage is neither possible nor need to design a high, lithium battery chemical properties determine a cell output voltage can only be about 3.6V, so Many batteries are used in three cascade way, 10.8V also became a very popular battery voltage. Some batteries are slightly larger than the integer value of 3.6V, such as 3.7V or 11.2V, etc., in fact, to protect the battery. Power supply, the situation is more complex, first of all need to add voltage to further regulation filter to ensure that the power performance is not very good in the case of stable work, the voltage regulator after the two parts of the city, all the way to the work of the power supply , The other way to the battery charge to the part of the power supply to the battery when the same power supply, and the part of the battery charge through the battery charge control circuit can be added to the battery, the control circuit can be very complex, so the power The voltage must be greater than the cell voltage to have sufficient capacity to supply the charge control circuit to the units. Finally the voltage actually added to the cell will never be the nominal voltage of your power supply. Rest assured.
Q:Who knows how the inverter is calculated?
There is no pole in the inverter, the electrode can be polarized, the greater the number of poles of the motor the slower the speed, please refer to.
