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:Will the motor suddenly stop when the inverter is suddenly powered down?
but there are exceptions, such as head pump, water hammer effect after power failure will make the motor Reversal
Q:What is the output voltage of the laptop power adapter?
Laptop power adapter output voltage, different brands may be different. Adapter output voltage is not a unified standard, different models are not the same notebook. The output voltage between 12V to 20V, 19V, 20V more.
Q:I have a 11KW-4 pole inverter, now with the 4KW-4 pole motor, what impact?
that is, the load is very heavy; caused by over-current burning inverter
Q:The relationship between the power supply of the notebook and the battery
1, when the notebook battery is fully charged, and connected to the power adapter, usually by the adapter directly to the host power supply, this time the battery is idle, the adapter power supply without battery conversion.
Q:Motor 2 pole and 4 pole in the inverter with what set to show
Motor parameters, there must be a parameter "motor pole" of the bar.
Q:Will the laptop's power adapter is not the original good?
Theoretically can be inserted into the use and will not have any obvious damage to the machine But it is best to buy the number of volt and your original consistent Original also has original benefits According to some "professional" sources claim that no original touchpad will have a slight jitter, I was not found
Q:Three-phase motor, quadrupole asynchronous motor to 15rpm, the inverter output how many volt voltage? The 4 V
The voltage is basically the same, the inverter changes the frequency of the power supply, not the voltage.
Q:Will the asynchronous motor pole change the number of speed control can also be combined with the frequency converter
but the use of the inverter is based on changes in the load by changing the frequency of power into the motor at any time speed control, you can achieve a smooth and accurate stepless speed control is Now widely used in a speed control method, especially for the load often change or often in the light load operation of the motor.
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:3.7KW inverter with 2.2KW 6-pole motor running to see the inverter shows the current is more than 4A, with the amount of clamp to 2.8A
2, upstairs brothers to answer the correct, the basic frequency is the following constant speed torque control, load changes little, the current change is not large.
