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: Laptop adapter
- The first of the power to be large, not recommended to use the second to replace the other 90W adapter size are similar, but if the computer is not installed when the battery, 65W can also be used, as long as the interface on the Oh
- Q: How do I protect the inverter when the three-phase two-pole motor is running?
- A: At this time to put the heart in the stomach, wait and see the change, what do not move (to prevent the accident to expand), until the motor stops, and then confirm, what kind of protection: alarm (alarm automatically after the release) or failure , Such as: over-voltage, overload, over-temperature, etc., and then the right medicine; inverter in the run which is not allowed, forced parking stop. Otherwise it will cause serious damage to the inverter.
- Q: Is the speed of the motor controlled?
- Slip motor is composed of ordinary squirrel cage asynchronous motor, electromagnetic slip clutch and electrical control device composed of three parts. Asynchronous motor, the stepper motor is used as the prime mover, and when it rotates, the armature of the clutch is rotated together. The electric control device is a device that provides the excitation current of the slip clutch excitation coil. Electromagnetic slip clutch, which includes armature, magnetic pole and excitation coil three parts.
- Q: I have a 11KW-4 pole inverter, now with the 4KW-4 pole motor, what impact?
- The inverter burns should be. Your motor overload is relatively large,
- Q: ABB frequency converter and the difference between domestic frequency converter
- Both the eyepiece and the objective lens are convex lenses with different focal lengths. The focal length of the convex lens of the objective lens is smaller than the focal length of the convex lens of the eyepiece.
- Q: Can the notebook's power adapter be mixed?
- This is a 90W power adapter This is Acer's 65W power adapter Here need to explain: General in the power adapter only shows the output voltage and current, not marked wattage, need to calculate their own. The value obtained by multiplying the number of voltages and the number of currents is the wattage. More on notebooks Related topics: Notebook forums hope that the above information is helpful to you
- 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: 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: What is the output voltage of the laptop power adapter?
- 16V to 20V, different brands may be different, 19V, 20V more.
- Q: The emitter E of the inverter inverter module and the AC output U are not directly connected together
- Pairs of modules are connected in a phase branch The phase output is derived from the neutral point between the modules
