Product Introduction

High-voltage frequency converter based on H bridge series units. High voltage inputs directly. In order to save energy, phase-shifting transformer inputs the low voltage on the second side to each power unit of H bridge and the output series of each phase and all power units connect so it has formed high voltage to drive the motor that. It’s a high-tech, green energy-saving product integrating advanced automatic control technology, high-power electric and electronic technology, fast and reliable fiber communication technology, high voltage technology and digital signal processing technology.

Q:The laptop's power adapter is too hot to do: Installed adapter heat should be no problem, I am now under the books, the fan mouth is very hot, the weather may be more and more hot it

Q:65w adapter and 90w laptop power adapter What is the difference?: In general, notebooks have to use power consumption is to decide whether to use 65W or 90W adapter power supply, but not to say that 90W must not use the 65W power supply, but his power is not reached, it is possible that the machine is using some of the features Can not start, for example, external equipment, power supply, if the original request is 90W power supply, but you are using the 65W power supply, external equipment can not work properly. But some cases do not need external equipment, so choose a small 65W power supply is very convenient

Q:Asus notebook power adapter how to open: if the power adapter is broken directly to the computer with a city on the line can not spend a few money back you can burn the computer is bigger to go to the computer The city took to repair and no one to repair to buy a very low price

Q:90KW inverter start 90KW, 4-pole motor and 6-pole motor j What is the difference? The inverter can be used for it?: Two motors can use the same frequency converter, but the motor nameplate data through the parameters to adjust the input when the inverter should pay attention to some

Q:What is the output voltage of the laptop power adapter?: Generally have 19V of the common friends, I was 19V

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:My laptop can not use the power adapter, and can only use the battery, how is it ah,: 1, laptop power adapter can not be used, first check the power outlet, plug, cable has no virtual state, if you can tell the normal equipment damage. Should be repaired. 2, the laptop battery must be charged through the power adapter or directly for the computer power, the power adapter is not missing, if you have experience can turn on the power adapter to see if the fuse is broken, try to update the fuse can be restored. If the integrated circuit is damaged, only updated.

Q:Does the teacher know the working principle of the inverter?: Very basic questions, the principle of fine you go online search, everywhere, I do not like to copy someone else, I simply tell you about: Voltage type inverter Three-phase alternating current to the rectifier module, converted into DC, filter stored in the electrolytic capacitor, IGBT + and - from the electrolytic capacitor to take energy, by the DSP (or other controller) output PWM pulse control IGBT turn on and off, So the output AC, the AC and input AC waveform is very different, so that the inverter is also a source of interference. Current filter in the middle of the filter is the inductor non-capacitance, we are more commonly used on the market and the economic converter are mostly voltage-type inverter.

Q:A water supply project, how to choose electrodes and frequency converters, such as giving a 7-storey water supply: 4. Set by pressure (0.3-0.4Mpa). Control the inverter can be.

Q:East yuan 7200GS inverter start 11KW 4-pole motor and 2-pole motor need to modify what parameters?: motor to be slightly larger, the speed of 4 pole speed is 1450 r / min, 2 pole is 970 r / min The With the inverter control, you only need to modify the parameters of which the motor parameters, and then the motor parameters from the study on it, the most important is your use of inverter equipment and control methods, and then the above two factors Feature adjustment parameters. There is to pay attention to the use of the inverter environment, the inverter is an electronic product, the environment is relatively high, in the use of as much as possible to improve the use of the environment.
