Product Description:

Mini Sensorless 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

MINI Series Frequency Inverter 220v 380v  from 0.4kw to 0.75kw


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.

EMC Standard Introduction

According to the requirements of national standard GB/T12668.3, the drive need to comply with electromagnetic interference and anti-electromagnetic interference two requirements. The existing products of the company execute the latest international standards: IEC/EN61800-3:2004(Adjustable speed electric SVFl power drive systems-part 3:EMC Requirements and specific test methods) which is equivalent to the national standard GB/T12668.3.

IEC/EN61800-3  inspects the drive from EMI and anti-EMI two aspects, EMI mainly tests the drive's radiation, conducted and  harmonic interferences ( Corresponding the civil drive has the requirement ). Anti-EMI mainly tests  the drive's conducted immunity, radiation immunity, surge immunity, fast mutant burst immunity,ESD immunity and power low frequency end immunity (Specific test items are: 1. the experiment of  input voltage dips, interruptions and changes immunity; 2, the experiment of commutation notches immunity ; 3, the experiment of harmonic input immunity ; 4, the experiment of input frequency change; 5, the experiment of input voltage unbalance; 6, the experiment of input voltage fluctuation).

According the stringent requirements of the IEC/EN61800-3 to test and according instructions shown in the 9.3 to install, Our products will have a good EMC for the general industrial environment.

Q:How to learn the inverter debugging and design parameters
Personally think it is relatively simple, and now the inverter has been more intelligent, and some simple applications, and even do not need to set the parameters.
Q:What are the types of power adapter used in notebooks?
The regulator wants the laptop adapter to not waste energy or add harmonics to the electricity lines. The first factor is that the adapter should plug the plug without any load, and it should be as small as possible to absorb power (standby). People are accustomed to the laptop adapter inserted in the socket, but not connected to the computer, the request can prevent the loss of this situation. The second factor is the recent requirement that it requires a specific average power efficiency at different load conditions (25%, 50%, 75%, and 100%) and is implemented by the global regulatory agencies in order to facilitate compliance with the specification And reduce overhead costs. Finally, the European and Japanese mandated reduction harmonics requirements have been applied to laptop power adapters because they have exceeded these standard specifications for the 75 W input power threshold. In a sense, the mobile / universal features of the laptop adapter make it the first mass production power product subject to the IEC1000-3-2 specification.
Q:The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!
4, high-speed motor: high-speed motor running process will produce a large number of harmonics, enhance the output current of the inverter, resulting in a lot of heat. Therefore, the inverter selection is also larger than the ordinary one gear. 5, explosion-proof motor: In some mines, oil extraction environment, the frequency conversion system is explosion-proof motor, the choice of inverter should use the explosion-proof function of the inverter, and the inverter placed in a safer place. 6, the degree of protection: for dust, wet applications, inverter selection should pay attention to its protection level. Or choose Ampang letter AMB inverter, the fan can also run in the water. 7, single-phase motor: When the scene using single-phase motor, the inverter useless. 8, variable pole motor: When the field using variable pole motor, the inverter selection should ensure that the maximum operating current should not exceed the rated current of the inverter
Q:On the notebook power adapter output current and voltage issues
This current is the maximum current value of the adapter output, Voltage matching, of course, can be charged. It is recommended to select an adapter with an output current value that is slightly larger than the original.
Q:4 pole 380V 4-5.5KW frequency conversion motor and inverter about how much money, such as the use of electromagnetic speed motor comparison
5.5 inverter motor around 2000 it is almost so much money electromagnetic speed does not know that we do not produce, but now the basic are the frequency of the world
Q:5.5 kW 4-pole motor with the fastest speed can exceed the rated speed?
Can not be exceeded Although the inverter can run out of the motor rated speed as the motor will soon burn You want your running speed of 2m / s you have to run 5m / s so go eggs do not pull the
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:Do not the laptop directly connected to the power adapter?
3, the notebook internal circuit using low-voltage direct current work, if the direct use of 220V AC and its connection will burn the circuit in the low-voltage devices, which is absolutely prohibited, but also basic common sense. At the same time, its external power jack is also dedicated, and the AC outlet is different;
Q:What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?
The soft starter is activated by adjusting the voltage and current, and the frequency converter starts the motor by changing the frequency of the power supply. The soft starter can theoretically smooth and gradually start the motor to the maximum speed. No impact current (ordinary start-up current is 6-7 times the rated current) The inverter is best suited for tap water and fans, etc. The soft starter is not suitable for everything except for heavy load start.
Q:Is it possible to use a different laptop's power adapter?
See the adapter is suitable for notebook models to use, the following three conditions for reference: 1. The output voltage of the adapter is the same as that of the notebook. 2. Is the adapter's output current consistent with the notebook's requirements? (Or a little bit of the current is also not.) 3. The size of the joint is appropriate. (If the connector is too loose, will be bad, excessive fever.) For DELL and HP / Compaq and other notebook power adapter, will involve a decoding problem. Please pay attention when the pro to buy. It is said that the market is also very popular universal adapter, a friend bought a LVSUN brand universal adapter LS-PAB90-BC10, with eight joints. Adapter has a liquid crystal display, you can automatically switch the voltage, very smart, with more than a year, has also been used
