Product Description:

11kw 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:Delta inverter reported CE4 reasons? Casually asked how many kinds of CE under a total
Is it right? The next manual to see do not understand
Q:Inverter problem
(0 ~ 20mA), but the main input / output is completely isolated, than the output of the inverter simulation of the output of the analog output The amount of signal impact resistance, anti-interference ability.
Q:How to choose a power adapter
Your notebook power part of the compatibility is very good, in a certain voltage range of power can be used long, but still please note on the notebook subject.
Q:What are the AC motor speed control methods? What are the characteristics of each
Pressure control speed, limited speed range is limited use of variable pole speed, change the motor internal wiring speed, speed is a very speed according to the motor factory set to brand speed to speed control, change the motor input Frequency to speed, are stepless speed is now more popular
Q:In the case of the inverter, why can not the normal operation after removing the gearbox? The motor is 4 pole.
If there is a load, it may be less than the torque. So it can not run.
Q:18: 5 kilowatts bipolar multi-pole pump motor with inverter
With a 18.5kw inverter can ah such as ABBACS510 series
Q:What is the difference between AC and DC frequency converters?
L inverter air conditioner refrigeration system components: inverter air conditioner by the compressor, evaporator, condenser, electromagnetic four-way valve, electronic expansion valve, defrost valve, double capillary and other components (see Figure II), work, air conditioner Room needs, automatic control of the inverter output frequency higher AC, the motor speed to speed up, the compressor cooling capacity increased to achieve the purpose of rapid cooling or heating, on the contrary, when the room cooling or heating less, Compressor to normal speed or lower speed operation, therefore, inverter air conditioner has a continuous cooling capacity adjustment, making the room temperature fluctuations smaller. In the process of compressor operation, the microcomputer system controls the inverter compressor at the same time, controls the opening degree of the electronic expansion valve, maintains the proper refrigerant flow, and directly changes the flow of the refrigerant in the evaporator to change its state, the compressor The speed corresponds to the opening degree of the expansion valve, and the displacement of the compressor corresponds to the supply amount of the expansion valve, so that the degree of superheat is not so large that the capacity of the evaporator is maximized, so that the refrigeration system The most efficient control.
Q:3.7KW inverter with 2.2KW 6-pole motor running to see the inverter shows the current is more than 4A, with the amount of clamp to 2.8A
2, upstairs brothers to answer the correct, the basic frequency is the following constant speed torque control, load changes little, the current change is not large.
Q:What is the maximum speed adjustable for a 4-stage motor with a rated frequency of 50Hz / 60Hz?
Motor speed and frequency of the formula N = 60f / p In the above formula N - the speed of the motor (r / min); 60 - per minute (seconds); F - power frequency (Hirsch); P - pole pairs of motor rotating magnetic fields. China provides the standard power frequency f = 50 weeks / second, so the rotation of the magnetic field of the size of the theoretical diameter only with the magnetic pole. The number of pole pairs is large, and the rotational speed of the rotating magnetic field is low.
Q:What is the laptop power adapter? Is it the battery?
Notebook power adapter, of course, is not referring to the laptop battery.
