Product Description:

15kw 380v 3 phase frequency inverter for air compressor  



General  :


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


Features:


(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:Who knows how the frequency converter works
2. flat wave circuit In addition, the ripple current generated by the inverter also changes the DC voltage. In order to suppress the voltage fluctuation, the inductor and the capacitor absorb the pulsating voltage (current). In general, the DC voltage of the rectifier is rectified and the DC voltage is rectified. General inverter power supply of the DC part of the main circuit in terms of margin, so eliminating the need for a simple capacitor filter smoothing circuit.
Q:Speed of 3000 r / min three-phase motor how to change its speed
Voltage regulator, variable pole speed, the best inverter speed. The
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:Is the laptop power adapter long-haul?
Oh, the power adapter is a transformer, we use the electricity is 220, after it will be converted into a suitable computer voltage, or notebook can not withstand 220V, so as long as the power inside the transformer will work, If you do not have a computer, it is best to unplug the plug on the power outlet, even if the computer has to pull out from the outlet, or will have an impact on the life of the adapter.
Q:55 瓩 4 pole motor with a frequency of one hour can save much electricity
it is used in the fan pump load can save about 14-22 kWh, used in the general category, on Multiply your number by 55.
Q:In the case of the inverter, why can not the normal operation after removing the gearbox? The motor is 4 pole.
If there is no load, the demolition of the gearbox is the same can be run.
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:What is the frequency converter used to do, why some motor with the inverter?
Speed control, there are speed requirements of the place are in the inverter
Q:How to disassemble the notebook power adapter
HP laptop power adapter for the whole design of small sealed, you can follow the following steps to dismantle: 1, laptop power adapter for the injection molding package or with a strong adhesive glue, without any screws, so generally only with violence Cracked. However, as long as the method properly, after the dismantling of the power adapter can be restored to the original, do not carefully observe almost no traces of open.
Q:Is it possible to use a different laptop's power adapter?
It is recommended to use the original comes with the adapter, different adapter output voltage is not the same
