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
SVF-G7 series VFD communicate with PC, PLC etc upper machines, and they need the support of standard expansion cards SC-EXT1-IO. And the cards supply RS485 communication interface. Between the upper user machine and frequency inverter communicate through the international standard ModBus communication, and the upper user machine as host machine, and the frequency inverter as slave machine. The communication content could be finished as follows: send operating command to frequency inverter, setting operating frequency, changing function code parameters, reading frequency inverter operation situation, monitoring parameters, fault information, function code etc.

- 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:Laptop warranty period is not over, the power adapter is broken, repair money?
- The general adapter is only one year warranty. And even some power warranty for three months.
Go to the official website of the notebook, see the specific information of the computer, which includes the computer parts of the specific warranty date and expiration date.
If the warranty period, as long as the purchase of the invoice, you can go to aftermarket replacement or maintenance.
Remember to bring an invoice, warranty card. It can not find the warranty card must find the invoice.
General power adapter is new.
- Q:What is the IGBT? Our inverter IGBT fried,
- Name is the FET, the price of this thing is more expensive,
- Q:I have a 11KW-4 pole inverter, now with the 4KW-4 pole motor, what impact?
- 11KW the following can be brought, the inverter rectifier module may be broken,
- Q:Is the laptop power adapter high temperature normal? Is there anything else?
- In fact, I am also facing such a problem, but I have solved:
First: you put the battery together, together with the power adapter, 1 hour after you will feel very hot, it is estimated that you say this. Although your battery is full of electricity.
Second: the battery removed, and then use the power adapter, 1 hour after you will feel the general heat, much better than the first case.
If you follow the above operation is what I said the same situation, it shows that your power adapter is no problem, because I specifically looking for professional after-sales such a problem, and later also detected the battery, are normal, so if you want is not very Hot, you can remove the battery.
- Q:A 4-pole AC motor into a 2-pole AC motor, the motor is controlled by the inverter, to make the maximum speed of the 2-pole motor and the original 4-pole
- First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
- Q:A water supply project, how to choose electrodes and frequency converters, such as giving a 7-storey water supply
- 1. Select the pressure pump head: 7 * 2.5 (3) = 17.5 (21) meters; this is the number of theory, in fact, should be selected 40 meters, (0.4Mpa).
- Q:First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
- In the inverter in the following 18.5kw inverter will bring their own braking unit for some special occasions, such as the inverter at high speed due to production needs, must be 1 second, or less time to stop, in the stop when the frequency The internal DC bus voltage is too high, the inverter will be reported over-voltage fault, in the positive and negative connected bk-dk connected to a resistor to the inverter discharge, the inverter will not report over-voltage failure
- Q:Can the laptop 1.3a power adapter be used on a 1.5a device?
- No, use a power adapter that is equal to or slightly larger than 1.5a.
- Q:380V 2 pole motor can use the inverter?
- At the same time, the paint is thick, the best 2 times dipping
Wiring with the end of the enameled wire end of the time, to use insulating materials separated better, more insurance
