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.

- Inquire about price/MOQ

Q:The laptop power adapter is burned
To be sure, the power adapter has a problem ~ ~ I suggest you if the warranty period to go after the sale of a ~ ~ If the insurance on Taobao Amoy on a ~ ~ ~
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:My Lenovo v450 laptop power adapter should be bad how to match?
In order to ensure quality, we recommend that you buy genuine, you can contact the service station to buy engineers
Q:How does the laptop's power adapter open
Notebook power adapter using the correct method] 1. Try to avoid the use of outdoor or harsh environments to prevent the adapter is exposed or damp. 2. When you are not using the adapter, please unplug the power plug. Because, for a long time the power will let the adapter has been in working condition, will affect the end of life. 3. Although the adapter is a broadband operating voltage, marked from 100V-240V can be, but if the voltage is extremely unstable in the case of use, the same will cause damage to the power adapter.
Q:On the notebook power adapter output current and voltage issues
On the real virtual cable that adapter is rectifier filter output, no regulator, the notebook internal regulator, the adapter does not need to regulator. 3.25A is smaller than 4.5A, because the adapter has a power margin that can be used. Summer attention to touch the adapter surface is overheating. Conditional or buy a large number of good current.
Q:Three-phase asynchronous AC motor speed control method
Second, the frequency control method Frequency control is to change the frequency of the motor stator power supply, thus changing its synchronous speed control method. Frequency converter system can be divided into AC - DC - AC inverter and AC - AC inverter two categories, most of the current domestic use - cross - frequency converter. Its characteristics: High efficiency, no additional loss during the speed control process; Wide range of applications, can be used for cage type asynchronous motor; Speed ​​range, the characteristics of hard, high precision; Complex technology, high cost, maintenance and repair difficult. This method is suitable for applications requiring high precision and better speed performance.
Q:What is the difference when using inverter frequency conversion ordinary motor and variable frequency inverter motor
2, the ordinary asynchronous motor is the cooling fan and motor spindle connection, the motor speed determines the cooling fan speed, low frequency when the motor rotation is slow, so the motor temperature rise is the principle.
Q:Laptop power adapter is broken, which brand is better domestic
This is usually very compatible with the power adapter brand, you can only buy the original, or to the local computer market with a similar output power adapter can be,
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:Why G120 inverter to be equipped with 4-pole motor?
On the upstairs that the motor parameters to be set on the possible, such as voltage, current, power, power factor, rated efficiency, rated frequency, rated speed, motor overload factor
