Q:400w 6-pole motor should be equipped with much of the inverter?: 0.75KW just fine, neither waste the inverter resources, but also to meet the occasional overload. And 0.75KW inverter is the standard model.

Q:The laptop power adapter is hot: My point of view: First: your laptop power supply in a small ventilation environment, resulting in poor heat dissipation, Second: the life of the power supply is 3-5 years, the gradual oxidation of electronic components and some of the aging components, resulting in no load and load a lot of power, Third: the battery close to each run, and then connected to the power, the power to the battery charger and notebook power supply, so the pressure is not hot strange.

Q:ASUS power adapter Acer can use it: 3. The size of the joint is appropriate. (If the connector is too loose, will be bad, excessive fever.) If it is for DELL and HP / Compaq and other notebook power adapter, will involve a decoding problem. Please pay attention when the pro to buy. Acer and Asus are not yet available. 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 also automatically switch the voltage, very smart, with more than a year, has also been used.

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: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:Short-term short-circuit converter DC link positive and negative will damage the inverter?: the switch signal Is the fan running up after the speed line is low, this can be shorted. Pulse is every turn a circle, send two pulses to the speed line

Q:Will the 75KW4 pole motor can be used to increase the speed of the inverter?: Can not, only slow down, on our national grid, 50HZ is the largest. At least with the inverter can not be achieved.

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 computer about electricity no electricity, is the power adapter problem?: To judge this is very simple: 1. The computer is in the battery state to see if it works properly. If it does not work, the battery has a problem 2. Remove the battery from the computer with a power adapter to see if it is working properly. If not, there is a problem with the power adapter 3. If the two states can work that is the computer charge management part of the poor contact and other issues.

Q:Inverter problem: (0 ~ 20mA), but the main input / output is completely isolated, than the output of the inverter simulation of the output of the analog output The amount of signal impact resistance, anti-interference ability.
