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 is the notebook with a power adapter?: Refer to the following factors when purchasing: Choose the brand: The principle is to choose the same type with the brand, if not, it can only find other brands. Now online to sell a lot of notebook power adapter are cut corners of the substandard products, the normal use of what should be no problem, once the accident will burn your laptop, save dozens of pieces but burn thousands of pieces of notebook worth the candle. (Such as the actual only 19V3.42A, but the standard 19V4.74A, this will lead to a very slow charge, and even damage the battery and laptop computers. There are some protection removed, this more horrible, there Accidentally burn the laptop.

Q:Can the HP laptop's power adapter be universal?: If the power adapter socket is the same as the output voltage can be common. But there are a few places to note, HP notebook power adapter output voltage there are many, the most common 19V and 18.5V, but even if the output voltage is the same, the output current may be different, that is, the output power is not the same , If your notebook needs a larger input power, then you have to use the match can be, the lower power may not make the battery normal use, and even harmful to the battery.

Q:Does the teacher know the working principle of the inverter?: The AC power rectification of the grid input is changed to direct current, and then the direct current is changed from AC by the control circuit according to the user's setting. The frequency is determined by the user. The motor is operated at this frequency to reach the change frequency. the goal of.

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:Laptop power adapter bad what is the phenomenon?: Either the power is bad or the machine on the power supply module is bad to repair service

Q:What is the principle and implementation of the inverter?: AC inverter principle. It is the first AC current will be converted into direct current, and then use the electronic components of the DC switch. AC power. General power of the larger inverter with a thyristor. And set an adjustable frequency device. The frequency in a certain range adjustable . Used to control the number of revolutions of the motor. The number of revolutions can be adjusted within a certain range. The frequency converter is widely used in the speed regulation of AC motor. Frequency control technology is an important development direction of modern power transmission technology, with power electronics Technology development, exchange 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:Will the 75KW4 pole motor can be used to increase the speed of the inverter?: Can not, only slow down, on our national grid, 50HZ is the largest. At least with the inverter can not be achieved.

Q:Computer frequency changer to do cd frequency changer how points positive and negative: . In this circuit, the total capacitance is 6500 microfarads, the voltage is doubled.

Q:Asus notebook power adapter how to open: if the power adapter is broken directly to the computer with a city on the line can not spend a few money back you can burn the computer is bigger to go to the computer The city took to repair and no one to repair to buy a very low price

Q:Three motors, if coupled with the governor speed, is it necessary to add the inverter?: ?Fifth, the hydraulic coupler speed: hydraulic coupler is a hydraulic transmission device, generally composed of the pump wheel and turbine, when the pump wheel in the prime mover driven under the rotation, in which the liquid is driven by the blade and rotation, in the Under the action of centrifugal force along the outer ring of the pump wheel into the turbine, in the same turn to the turbine blades to thrust, to drive the production machinery operation. Through different hydraulic (lubricants and turbines) to achieve speed.
