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 power adapter is used to do what
Simply put the transfer into DC China's electricity is 220V AC, and the notebook is a direct current, the need for adapter to rectify, filter, regulator, and finally we need to form a direct current
Q:Can the inverter be used to control the speed of the DC motor?
The inverter can be used to control the speed of the DC motor. Inverter control DC motor is to control the DC motor. Inverter is the application of frequency conversion technology and microelectronics technology to change the AC power frequency and effective voltage power control equipment. The frequency converter is usually used to control the AC motor. Inverter at work can change the AC power frequency and effective voltage, another point of view, is the inverter in the control output (injected into the controlled device) AC frequency, but also control the output of the effective power. A DC motor is a rotating electric machine that converts DC power into mechanical energy. DC motor coil in the current must be in accordance with certain changes (commutation) can be rotated, according to the principle of commutation DC motor can be divided into brush and brushless motor two categories.
Q:Why the number of motor poles increased, the inverter capacity will increase
The relationship between the motor current and the power is The power is equal to the current and voltage of the product again good with the power factor. (Simplex)
Q:What is the adapter?
An adapter is a physical device that allows a hardware or electronic interface to interface with another hardware or electronic interface (adapt and without any loss).
Q:380V 2 pole motor can use the inverter?
Of course, the stator winding can be connected with concentric While enameled wire to be better, preferably 180 degrees or 155, and even dedicated enameled wire
Q:How to choose the inverter
and you need to know how The use of frequency converter, as well as voltage 380, are fixed, and the frequency can be changed
Q:Laptop power adapter aging
First, the laptop power adapter is digital transformer, under normal circumstances either damaged, either available, no low voltage. Second, the notebook to play large games up to make the notebook because of poor heat dissipation caused by high temperature automatically shut down, not because of lack of power caused by automatic shutdown.
Q:What is the base blockade in the drive?
Normal work, the bridge between the upper and lower pipes can not be turned on at the same time, while conduction will occur short-circuit accident. It is necessary to open a tube at the same time block the same bridge of the other pipe base can be safe to work.
Q:Laptop power adapter how to detect?
After opening to see what is burned, Estimated to be insurance and the like
Q:What is the IGBT? Our inverter IGBT fried,
Name is the FET, the price of this thing is more expensive,
