Product Description:

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





TechnicalAdvantage

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:Why the notebook power adapter can not be universal
First, the interface is different Most laptop power adapter brands have different interfaces, which means that other brands of power adapters can not be plugged into your laptop for power supply. The interface is relatively safe, because at least you will not plug in the current or voltage does not meet the power adapter to the laptop power supply, which led to computer hardware damage.
Q:Is the inverter output current proportional to the output torque?
The output voltage of the inverter is proportional to the frequency, which is to keep the motor flux constant, T = KIφ so the motor output torque is proportional to the inverter current.
Q:ASUS and dell notebook power adapter can be universal?
One, not necessarily interchangeable. Need to compare the two adapter specifications to determine: 1, the books power adapter, there are 90W and 60W of the other, some products output voltage 19V and 14V of the other. "General" conditions, as long as the output power of the adapter is the same, the output voltage is the same (current may not consider), that is, their specifications are the same, you can directly substitute. 2, however, some foreign imports of products using 110V AC products, be careful to see clearly. 3, before the use of replacement, pay attention to observe if connected to the books of the power plug specifications are different, you can not directly insert. An interface adapter can be purchased. Can also be bad adapter plug, cut into the replacement adapter; Second, for example: 1, LITEON OEM products, parameters: input AC 100 ~ 240V 1.5A, output DC 19V3.42A. Rated output power 60W; 2, ASUS books supporting products, parameters: AC 100 ~ 240V 1.5A, output DC 19V 4.74A. Rated output power 90W.
Q:There is no inverter comes with simple PLC programming function
The inverter is an AC speed control device, like DC speed control device, DC speed is to change the armature and excitation current, and it is the input AC through the internal circuit into DC, DC and then DC, the last DC AC output, this is the original 50Hz frequency AC can output other frequencies of alternating current, because the speed v is proportional to the frequency f, so you can set the frequency of the inverter to change the speed of the control motor. It does not have its own programming function. But there are servo drives, in fact, is a frequency converter, but can handle some of their own signals, usually from the servo motor on the encoder, and then control the servo motor to achieve precise control.
Q:What is the working principle of high voltage electrodes and frequency converters?
The general high and low methods are used in low-power high-voltage motor to do with energy-saving energy. Low-high-mode high-voltage inverter is controlled by a low-voltage inverter, the voltage directly to the motor with a step-up transformer voltage. Low-high mode is also used in low-power high-voltage motor to do with energy-saving energy.
Q:Laptop warranty period is not over, the power adapter is broken, repair money?
Look at your reinsurance period if not in the warranty period is not man-made damage can be changed or for the change
Q:Laptop adapter heat
Many friends to buy a laptop or laptop power, you may encounter the power did not take long to heat on the hot, and even hot to dare not get the situation, in the end is the quality of power problems or how is it? With the ever-changing notebook frequency, notebook power adapter power is also sesame flowering high, even to 100W or so, almost a small desktop power! Touch the hand, timid may be scared, obediently, is simply a hot potato! What will not fire? This is a lot of people worry! Compaq, IBM, such a large company to recover several back to the power adapter, it is because of fear that there may be defects due to power supply design, and will cause a fire!
Q:What is the maximum speed adjustable for a 4-stage motor with a rated frequency of 50Hz / 60Hz?
Motor speed and frequency of the formula N = 60f / p In the above formula N - the speed of the motor (r / min); 60 - per minute (seconds); F - power frequency (Hirsch); P - pole pairs of motor rotating magnetic fields. China provides the standard power frequency f = 50 weeks / second, so the rotation of the magnetic field of the size of the theoretical diameter only with the magnetic pole. The number of pole pairs is large, and the rotational speed of the rotating magnetic field is low.
Q:The inverter is running independently
Frequency conversion regulator is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on. The inverter will adjust the voltage and frequency of the output power supply according to the breaking of the internal IGBT, and provide the required power supply voltage according to the actual needs of the motor, so as to achieve the goal of saving energy and speeding.
Q:Inverter with 2.2KW 6 pole motor. 1 minute 8 times reversing often burn the motor, how to solve. For the 2 pole 4KW motor is the same.
7 seconds more than a change, too often. It is estimated that the inverter will not work. Suggest:
