MN Series 220v from 0.4kw Frequency Inverter AC Driver

 

SVF-MN

MiniSensorless Vector Frequency Inverter

Voltage and power range

3phase, 380v: 0.4~5.5kw

3/1 phase, 220v: 0.4~3.7kw

Output frequency range: 0.00Hz-400.00 Hz


Technical Advantage

Control mode

(1) VF control: Multipoint VF curve. This apply to the situation that one frequencyinverter drives multiple motors, such as fan, water pump, engraving machine,injection molding machine etc.

(2) Open-loop vector control: Steady speed with highprecision, wide range of speed governing, as the speed ratio is 1:150 and frequencyis 0.5Hz, we could output 150% rated torque. Good dynamic performance.

Q:Laptop power adapter is used to do what
Power and charge the notebook. Equivalent to power, mobile phone charger.
Q:What is the frequency of `30 points
frequency conversion By changing the AC frequency of the way to achieve AC power control technology is called frequency conversion technology
Q:Who knows how the inverter is calculated?
The synchronous speed of the two-pole motor is 3000 rpm,
Q:Computer frequency changer to do cd frequency changer how points positive and negative
This inverter is 380V of the bar, the capacitor series is to increase the pressure, and then parallel to increase the capacity of the capacity of the capacitor and the inverter is proportional to the power, the greater the capacity of the capacitor capacity requirements are greater.
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.
Q:2 pole 0.75 kW motor can increase the speed through the inverter?
if the 4-pole motor to rise to 2-pole motor frequency, The frequency of the motor rises to about 100 Hz, which is easy to implement for the frequency converter.
Q:What is the characteristic of the variable pole speed method?
Three-phase asynchronous motor speed formula: n = 60f / p (1-s) From the above equation can be seen, change the power supply frequency f, the motor pole p and slip rate s can achieve the purpose of changing the speed. From the nature of the speed point of view, different speed control mode is nothing more than to change the AC motor synchronous speed or do not change the synchronous turn two. In the production machinery is widely used does not change the synchronous speed of the speed control method There are winding motor rotor resistance, chopping speed, cascade speed and the application of electromagnetic slip clutch, hydraulic coupling, oil film clutch, etc. Speed ​​control. Change the synchronous speed of the stator to change the number of pole pairs of multi-speed motor, change the stator voltage, the frequency of the frequency control can not change the motor speed and so on. From the energy point of view of the speed control point of view, there are two methods of efficient speed control and inefficient speed control: high speed control when the slip rate is constant, so no slip loss, such as multi-speed motor, frequency control As well as the speed loss can be recovered speed control methods (such as cascade speed, etc.). There are slip loss of the speed control method is a low efficiency, such as the rotor string resistance control method, the energy loss in the rotor circuit; electromagnetic clutch speed control method, the energy loss in the clutch coil; hydraulic coupling speed , Energy loss in the oil of the hydraulic coupling. In general, the slip loss increases with the speed range, if the speed range is not large, the energy loss is very small.
Q:Inverter principle eff23
For vectors such as vector-controlled frequency converters that require a lot of computation, there is sometimes a need for a torque calculation CPU and some corresponding circuits. Frequency control is by changing the motor stator winding power supply to achieve the purpose of speed.
Q:ASUS and dell notebook power adapter can be universal?
I can not remember to insert into the ah. The Looks like DELL that interface is very special
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.
