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:What is the output voltage of the laptop power adapter?
16V to 20V, different brands may be different, 19V, 20V more.
Q:What is the motor series parameter setting of the inverter? If it is with the spindle,
The motor series setting of the inverter should be set according to the series of motor
Q:Inverter principle eff23
The basic principle of the inverter The inverter is a device that converts the power frequency (50Hz or 60Hz) into AC power of various frequencies to realize the variable speed operation of the motor. The control circuit completes the control of the main circuit, and the rectifier circuit converts the alternating current into direct current and DC Circuit rectifier circuit output smooth filter, the inverter circuit will reverse into the DC power.
Q:2 pole 0.75 kW motor can increase the speed through the inverter?
2-pole motor speed of about 2900 r / min or so, 4-pole motor speed of about 1400 r / min or so, which are in the case of 50HZ,
Q:The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!
1. submersible pumps are generally the problem, far away from the reflection voltage, the pump insulation breakdown, in particular, to better pump. 2. Distance away, the inverter and pump connection thicker. 3. Then on the output filter.
Q:The laptop's power adapter is broken how much it costs
Buy a new, new price of dozens to one hundred. Notebook adapter, as long as the output current is greater than the old, the same voltage, with the brand can be interchangeable, Different brands of adapters to meet the above requirements, that is, insert the notebook connector is different, you can use scissors + tape,
Q:ASUS power adapter Acer can use it
See whether the power adapter is suitable for notebook use, the following three conditions for reference: 1. The output voltage of the adapter is the same as that of the notebook.
Q:My inverter is the era TVF8000 series, the motor is 15KW6 pole motor, has been used for 3 years.
For your situation about the summary of recommendations: First, check whether the motor overload and whether the leakage exceeded, Second, check and clean the inverter fan, if the room temperature is high, add the external fan to the inverter cooling Third, if none of the above, then please check the inverter module is burned, replace the module Fourth, if the inverter is no problem, then the motor and load the problem, if the motor problems are not resolved, then only re-select the inverter, please select the time to increase the margin
Q:Who knows how the inverter is calculated?
The synchronous speed of the two-pole motor is 3000 rpm,
Q:Laptop power adapter aging
This is not much relationship with the adapter, is your laptop internal hardware overheating, leading to self-protection open and shut down.
