Product Description:

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 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 difference when using inverter frequency conversion ordinary motor and variable frequency inverter motor
So that mainly depends on your application and the frequency of work in the number.
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:Whether the inverter can control the start and stop of the horizontal monopole centrifugal pump
Hi, the inverter control is no problem. You need to select the inverter by the load characteristics of the centrifugal pump, consider: Centrifugal pump rated working current, overload capacity, parking whether there is emergency stop request. I used the inverter to control the horizontal centrifuge some time ago.
Q:Does the teacher know the working principle of the inverter?
At present the main inverter is Mitsubishi you can go to their domestic sales site to find a specific inverter manual has a detailed explanation Also popular said that the inverter is to change the operating frequency of some mechanical equipment control devices, such as motors, pumps, etc.
Q:How does the laptop's power adapter open
Control Panel - System - Hardware - Device Manager - Network Adapter, right click, and the menu appears. If it is infinite, then first follow the above argument to see if it can be enabled.
Q:Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
Inverters Have not heard of it! East yuan heard. The inverter is most likely to be damaged by the motor is running suddenly grounded, the possibility of frying the module more than eighty percent, since a little better brand will blow up! Overload, overcurrent, short circuit, lack of phase caused by damage to the inverter, then the quality of the inverter is so good, and indeed the basic functions of these inverter protection.
Q:Why the number of motor poles increased, the inverter capacity will increase
The power of the three-phase motor is equal to the root number of 3 times the line current and the line voltage of the product again good with the power factor. Can also be 3 times the phase current and phase voltage of the good product and then good to power factor. The frequency converter should match the rated current of the motor, not the power of the motor.
Q:Please recommend a high performance laptop power adapter?
Power adapter can recommend you what model you get what model ah he is a standard can not just recommend
Q:Three motors, if coupled with the governor speed, is it necessary to add the inverter?
  Third, the cascade speed: Cascade speed refers to the winding motor rotor loop in the adjustable resistance to change the motor slip, to speed the purpose of the past, the most widely used.
