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: The inverter control power is also the same, the pole is not the same as the motor 6 or 4 pole can be used?
- can use. But in the inverter "motor parameters" to be some changes. Such as the number of poles, rated current.
- Q: How to choose the right inverter?
- 2, constant torque load Constant torque load equipment requires low frequency inverter torque, dynamic response speed. Inverter 0HZ vector state, to 150% of the torque, to meet the needs of various conditions. For example: a dredger owner bucket inverter system, is a constant torque load, dual motor, and the load overload time is long, so the inverter configuration configuration to enlarge the two models of the G-type machine, while the power supply for the device Machine power supply, the inverter must be configured to input AC reactor.
- 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: Can the inverter stop intermittently during operation? If so, how to connect and set up
- Look at your inverter manual, because the inverter is not a simple wiring can run, first of all have to know that a few are external terminals (inverter input terminals),
- Q: Pump frequency converter instantaneous restart and restart the problem
- How the frequency converter works: The frequency converter is a power control device that transforms the power frequency power supply into another frequency by the on-off function of the power semiconductor device. We are now using the inverter is mainly used to pay - straight - cross mode (VVVF frequency conversion or vector control frequency), the first frequency AC power through the rectifier into a DC power supply, and then convert the DC power supply frequency, voltage can be controlled AC power supply to the motor. The circuit of the inverter is usually composed of four parts: rectifier, intermediate DC link, inverter and control. Rectifier part of the three-phase bridge uncontrollable rectifier, inverter part of the IGBT three-phase bridge inverter, and the output for the PWM waveform, the middle of the DC link for the filter, DC energy storage and buffer reactive power.
- Q: Is the speed of the motor controlled?
- Change the external conditions, you can change the motor speed: 1. Change the number of pole pairs of the motor. (Multi-pole motor use) 2. Use the frequency converter to change the frequency speed 3. Winding motor rotor series resistance speed control. 4. Slip motor is to change the slip electromagnetic speed
- Q: Acer laptop power adapter
- It might be bad, you have to determine whether the adapter or adapter adapter directly change.
- Q: Do you need to rectify before switching?
- Need to rectify. The inverter is actually an inverter, which first turns the alternating current into direct current, then switches the DC power with the electronic components, changes to alternating current, and the general-purpose inverter is equipped with a thyristor and an adjustable frequency The frequency is adjustable in a certain range, and it is used to control the number of revolutions of the motor, so that the number of revolutions can be adjusted within a certain range.The frequency converter is widely used in the speed regulation of AC motor. Technology development direction, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply and other fields. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.
- Q: 90KW inverter start 90KW, 4-pole motor and 6-pole motor j What is the difference? The inverter can be used for it?
- Two motors can use the same frequency converter, but the motor nameplate data through the parameters to adjust the input when the inverter should pay attention to some
- Q: 380V 2 pole motor can use the inverter?
- At the same time, the paint is thick, the best 2 times dipping Wiring with the end of the enameled wire end of the time, to use insulating materials separated better, more insurance
