Product Description:

15kw 380v 3 phase frequency inverter for air compressor  



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


(1) VF control: Multiple curve could been chosen, Linear V/F curve, 2.0 times power drop torque V/F curve, custom V/F percentage(can realize manual energy saving control), multipoint VF curve. This apply to the situation that one frequency inverter drives multiple motors, such as fan, water pump, engraving machine, injection molding machine etc.


(2) Open-loop vector control: Steady speed with high precision, wide range of speed governing, as the speed ratio is 1:200 and 180% rated torque could be output in 0.5Hz. Good dynamic performance.

Open-loop vector is suitable for high-Performance universal occasions such as machine tools, centrifuges, cranes and handling equipment, rolling mill and other loads.


(3) Torque control: Fast torque response,<20ms, precision torque: <5%, applied to winding, drawing and other occasions.

Q:What is the output voltage of the laptop power adapter?
Laptop power adapter output voltage, different brands may be different. Adapter output voltage is not a unified standard, different models are not the same notebook. The output voltage between 12V to 20V, 19V, 20V more.
Q:There is no inverter comes with simple PLC programming function
The inverter is an AC speed control device, like DC speed control device, DC speed is to change the armature and excitation current, and it is the input AC through the internal circuit into DC, DC and then DC, the last DC AC output, this is the original 50Hz frequency AC can output other frequencies of alternating current, because the speed v is proportional to the frequency f, so you can set the frequency of the inverter to change the speed of the control motor. It does not have its own programming function. But there are servo drives, in fact, is a frequency converter, but can handle some of their own signals, usually from the servo motor on the encoder, and then control the servo motor to achieve precise control.
Q:Fuji inverter motor set the number of poles will not have any effect?
The number of motor poles corresponds to the speed of the motor, the number of poles is not set when the speed of the control error, in the high speed requirements of the transmission is not allowed.
Q:On the notebook power adapter output current and voltage issues
This current is the maximum current value of the adapter output, Voltage matching, of course, can be charged. It is recommended to select an adapter with an output current value that is slightly larger than the original.
Q:Does the teacher know the working principle of the inverter?
Very basic questions, the principle of fine you go online search, everywhere, I do not like to copy someone else, I simply tell you about: Voltage type inverter Three-phase alternating current to the rectifier module, converted into DC, filter stored in the electrolytic capacitor, IGBT + and - from the electrolytic capacitor to take energy, by the DSP (or other controller) output PWM pulse control IGBT turn on and off, So the output AC, the AC and input AC waveform is very different, so that the inverter is also a source of interference. Current filter in the middle of the filter is the inductor non-capacitance, we are more commonly used on the market and the economic converter are mostly voltage-type inverter.
Q:What parts of the inverter composition
The main converter are: rectifier module, inverter module, capacitor, driver board, motherboard, shell composed of these parts!
Q:Will the 75KW4 pole motor can be used to increase the speed of the inverter?
China's power frequency 50hz, and the motor rated frequency match, blindly by increasing the frequency of the inverter output motor speed is not desirable, will affect the motor magnetic circuit, work is not normal.
Q:22kw.2 pole fan can use Fuji inverter?
according to the rated name of the fan brand and the inverter rated current control, select the current value match, or slightly larger The
Q:My motor is a low frequency 8 pole motor, about 80W. I would like to choose a frequency converter
So small, with the domestic 400-watt, Shenzhen a lot
Q:The Schneider inverter reports the nlp command
Schneider inverter reported nlp ??? main circuit no electricity 1 re-power up 2 connected to the DC reactor terminals PO, PA / + between the short wiring, the main circuit can not be powered
