Product Description:

  ac variable frequency drive for 3 phase water pump and blower with best quality and price

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 adapter
This principle is not, try, look at how the charge situation, if you can charge, can be filled, just a long time, to no harm However, the heat may be high, long-term so, there is a risk
Q:6-pole motor, speed 8000 rpm, corresponding to the frequency converter output frequency is how much?
To 400HZ, so high frequency you tried it? I only tried 80HZ, if you tried, please tell me some of the high frequency of the actual situation will produce some changes in the motor,
Q:Laptop power adapter current is not the same alternative?
The adapter is the voltage source, the actual output current depends on the size of the load resistance,
Q:Octopus AC Servo motor can be driven with ordinary inverter?
First look at AC Servo motor motor type, synchronous motor or asynchronous motor;
Q:Inverter 0.2KW, the motor speed requirements down to 4 turn, the motor pole 4 pole. Can the drive drive the motor?
You can only use constant torque type of inverter. Motor selection frequency conversion motor. Driving is no problem
Q:First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
In short, then connected to the bk-dk electrical appliances, is a resistor for the discharge effect
Q:Is the laptop power adapter long-haul?
Can, rarely say there is a power adapter without power and failure, my notebook 5 years, never pull the power adapter plug, never power, there is no problem. Of course, save electricity and care from the point of view, it is recommended to pull the best, because the adapter is still in the working state.
Q:Yasukawa inverter reported bb code that is the reason why the base blockade?
This should be the meaning of the drive block, that is, the drive signal is locked, there is no drive signal, and start a frequency change but no voltage output, you find someone to repair the circuit board can be used normally, this is generally the circuit board Problem, the module is less likely to be bad
Q:Laptop computer about electricity no electricity, is the power adapter problem?
To judge this is very simple: 1. The computer is in the battery state to see if it works properly. If it does not work, the battery has a problem 2. Remove the battery from the computer with a power adapter to see if it is working properly. If not, there is a problem with the power adapter 3. If the two states can work that is the computer charge management part of the poor contact and other issues.
Q:Laptop warranty period is not over, the power adapter is broken, repair money?
Do not money, first to see where the dealer, if there is no answer, went directly to the repair station, with a good warranty card and other things, that reason you can! The
