Product Description:

5.5kw 400v 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:How to choose the right inverter?
, fan, pump load This is the most suitable for use in frequency conversion speed of the scene environment, the inverter function technology is not too high requirements, the use of inverter energy saving effect is remarkable. For example: a large-scale heating equipment in a large-scale heating system, including blower, induced draft fan (centrifugal fan) inverter configuration configuration with the power of the P-type machine; water pump (centrifugal pump) inverter configuration configuration with the power of the P-type machine ; Conveyor pump frequency converter selection configuration with the power of G-type machine; belt machine (coal feeder) inverter configuration configuration to enlarge a file of the G-type machine; slag converter inverter configuration configuration to enlarge a file of the G-type machine; Crusher (coal crusher) inverter configuration configuration to enlarge a file or two stalls of the G-type machine.
Q:How does the variable frequency motor output torque at very low frequencies?
1, to improve the slip of the inverter compensation coefficient 2, to improve the continuous lifting coefficient of the inverter, but the coefficient is too high there will be overcurrent. 3, with no sensor vector control can increase the motor output torque or encoder with the vector control can make the motor at low frequency to achieve the rated output torque.
Q:Three-phase motor, quadrupole asynchronous motor to 15rpm, the inverter output how many volt voltage? The 4 V
The voltage is basically the same, the inverter changes the frequency of the power supply, not the voltage.
Q:Can different brands of laptop power adapters be generic?
1, strictly speaking, different brands of laptop power adapter is not common. Even if the logo on the voltage and current are the same should not be mixed, will cause the power interface or motherboard failure or even damage. 2, with the same brand of different models of the power can be used temporarily, but should not be used for too long. 3, the cottage power adapter is best not to buy the use of hidden dangers, including spontaneous combustion and explosion, try to use the original power adapter.
Q:How to learn the inverter debugging and design parameters
Personally think it is relatively simple, and now the inverter has been more intelligent, and some simple applications, and even do not need to set the parameters.
Q:What is the difference when using inverter frequency conversion ordinary motor and variable frequency inverter motor
So that mainly depends on your application and the frequency of work in the number.
Q:Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
If you buy the inverter and the motor can match, it is certainly the quality of the inverter.

Wrqwgp520 | viewed 4426 times Recommended at 2016-05-26 08:52:41 Best answer Lenovo Lenovo 19V4.74A G450 G470 Laptop AC Adapter: 【Power supply technical parameters】 1. Input voltage: AC100-240V.50-60Hz.1.5A 2. Output voltage: 19V 3. Output current: 4.74A 4. Work efficiency:> 85% 5. Output power: 90W 6: Input interface: Plum triangular interface 7: Output interface: 5.5 * 2.5
Q:Laptop power adapter repair how much money
Dell laptop warranty 36 months of hardware include: CPU, memory. Warranty 24 months of hardware include: motherboard, graphics card, LCD screen, hard drive, power adapter, keyboard, mouse module. Warranty 12 months of hardware include: LCD accessories, CD-ROM, DVD, CDR / W, floppy drive, Modem card, network card, camera and other functional modules and components. Battery warranty for 3 months. Random disc, random gift of micro-computer products such as warranty 3 months. The
Q:Speed of 3000 r / min three-phase motor how to change its speed
Voltage regulator, variable pole speed, the best inverter speed. The
