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?
- Inverter selection science or not for the normal operation of the frequency conversion system is essential. Many beginners on the general inverter selection method is not enough understanding, or even know the method, not sure the choice of the inverter model is positive solution, the following for everyone to solve the mystery. Inverter selection first look at the AC motor. Because the frequency conversion system generally first determine the motor, then select the inverter. In principle, it is necessary to determine the inverter model based on the actual current at which the AC motor is operating for a long time, and not on the motor nameplate. Inverter selection next depends on the load type. Frequency conversion system driven load equipment can be divided into three types: constant torque load, constant power load, fan, pump load, different load type select the inverter model is different.
- Q:Can the laptop power adapter be generic?
- Output voltage, current, interface can be used as well.
- Q:How does the variable frequency motor output torque at very low frequencies?
- Low frequency, the motor torque is relatively low, generally VF inverter performance is good or bad, the price level reflected in this time. But there is torque to enhance the function, it will not move without moving. If no load can not start, check the motor card and other mechanical problems such as whether there is a problem.
- Q:Laptop adapter heat
- In fact, as long as the power adapter temperature is within the design range, that is, the temperature in the normal range, the general is not dangerous! So why is the power supply hot? What kind of temperature range is the normal range? Switching power supply conversion efficiency can only reach 75% -85% or so. The answer is here. Switching power supply conversion efficiency is high enough, it is still difficult to find a better way to convert. Switching power supply in the voltage conversion, a part of the energy loss, in addition to a small part of the loss in the form of waves, the majority of the way out of the heat. Switching power supply power is missing, the loss of energy is also missing, the power of the heat is also large. This is why the desktop power supply to add a fan for cooling reasons. We may wish to count, a 100W switching power supply, in the use of how much energy loss in the above!
- Q:Is the laptop power adapter long-haul?
- Can, rarely say there is a power adapter without power and failure, my notebook 5 years, never pull the power adapter plug, never power, there is no problem. Of course, save electricity and care from the point of view, it is recommended to pull the best, because the adapter is still in the working state.
- Q:Taian inverter 3.7KW 380V with 4.0KW 2 pole motor 18000 to 300HZ can it?
- With green wave Jie can experience to judge, there may be two possibilities: First, the inverter power selected small. Bipolar motor, not a four-pole motor, the inverter is designed according to the four-pole motor model, so in the inverter selection, can not only look at the power, but also the rated current of the motor;
- Q:I power adapter output current 3.25A for a 4.5A, can you use it
- As long as the same voltage with the same polarity on the connector can! The The This can also increase the stability of the computer ^ _ ^, and to speed up the role of charging time, in short, will not cause a bad impact on the computer.
- Q:380V motor addition to the inverter, but also how to change its speed?
- Rotary motor rotor series resistance adjustable speed. 4. Change the slip electromagnetic speed (slip motor)
- 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: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.
