FAQ

What is the delivery time?

We can delivery the goods within 5 days after receiving your payment.

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: How is the notebook with a power adapter?: The safest option is to choose the same type of notebook power adapter. When in some cases (the original adapter is too expensive or not available), you can select the operating parameters and output connectors and the original adapter.

Q: 6-pole motor, speed 8000 rpm, corresponding to the frequency converter output frequency is how much?: The synchronous speed of the motor is n = 60f / p P is the pole pair number, and f is the power supply frequency. The pole pair number of the 6 pole motor is 3. Therefore, f = n * p / 60 = 8000 * 3/60 = 400Hz.

Q: Variable frequency pump pressure in the very low flow instability, why?: From the performance curve, the flow becomes smaller, the combination of pressure and frequency adjustment flow will only stabilize the flow at a small value, the pressure will be reduced, because the work point will move down.

Q: Master Hello a machine requires 500 speed matching 6-pole motor frequency converter transferred to about 28HZ: The belt rotation is calculated by the speed ratio. The current transferred to the motor by the inverter is approximately equal to the rated current of the motor, ie the motor's power is maximized.

Q: Inverter problem: A: The inverter output 4 ~ 20mA (0 ~ 20mA), the analog signal can be directly connected to the measuring instrument, the daily design, installation, application are so, as long as the selection is correct, there will be no problem.

Q: What is the difference between AC and DC frequency converters?: Advantages and disadvantages: Advantages: inverter air conditioner with variable frequency power supply, inverter compressor, electronic expansion valve and microcomputer technology, the organic combination of air conditioning to further improve the performance, the use of room temperature fluctuations, better comfort, the better Power supply voltage fluctuation is not sensitive, the compressor starts, the general non-stop, cooling capacity in the range of 35% to 117% change, to avoid the frequent open air-conditioning, to extend the life of the compressor, while efficient, Features. Disadvantages: the price is more expensive, compared with ordinary air conditioning, about 1/3 to 1/4 of the price, at the same time, because the inverter air conditioner control system and frequency conversion system is more complex, higher requirements for components, compared to ordinary air conditioning , Inverter air conditioner failure rate is high, and, due to the use of frequency conversion technology, at the same time, will produce harmonic pollution. What is DC inverter air conditioner? DC inverter air conditioner is relative to the AC inverter air conditioner, in fact, its name is not correct, because the DC and no frequency, it is by changing the DC voltage to adjust the compressor speed, thus changing the air conditioning cooling capacity, It can only be said to be a DC variable speed air conditioning, not strictly in the sense of inverter air conditioner.

Q: Who knows how the inverter is calculated?: Quadrupole motor synchronous speed is: 1500 r / min, but the actual motor speed will be more than 14 turn.

Q: Inverter 0.2KW, the motor speed requirements down to 4 turn, the motor pole 4 pole. Can the drive drive the motor?: Can, but this is a test product, the application does not try!

Q: Three sets of batteries (540V) DC power supply U / f inverter.: It is estimated that the battery should be string - and - series connection method, and then rectifier part of the converter (which may also be caused by the switch) is actually a series of diodes in series, positive and negative after the reverse is actually the battery is Negative shorts, resulting in burning, as to burn only one of the group of a few cells, it should be string - and - string and that group, because the parallel to bear it double voltage.
