Q:Inverter signal line analog 4-20mA connection positive and negative can be reversed?
Inverter signal line analog 4-20mA connection when the positive and negative is not reversed. Inverter input analog signal is generally 4-20mA, 0-20mA, 0-5V, 0-10V and so on.
Q:How does the laptop's power adapter open
Control Panel - System - Hardware - Device Manager - Network Adapter, right click, and the menu appears. If it is infinite, then first follow the above argument to see if it can be enabled.
Q:Who knows how the frequency converter works
The inverter is actually an inverter, which first turns the alternating current into direct current, and then switches the DC power with the electronic components into AC power, and the inverter is equipped with a variable frequency The frequency is adjustable in a certain range, and it is used to control the number of revolutions of the motor, so that the number of revolutions can be adjusted within a certain range.The frequency converter is widely used in the speed regulation of AC motor. Technology development direction, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply and other fields. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.
Q:Notebook power adapter on how to look at power
then the same formula can be used to calculate: power (unit: W) = voltage (unit: V) × current (unit: A). For example: the power adapter only identifies the output voltage is 20V, the output current is 4.5A, then we set a formula to know the output power is 20 × 4.5 = 90W.
Q:I have a 5.5 kilowatts of 4-pole motor, want to pass through the inverter, slow down to 130 per minute use, eliminating the need for speed,
wo recommendations, the first, the use of vector control of the inverter, you are expected to run the frequency of about 5Hz, this time, ordinary V / F inverter output torque may be small, not necessarily meet the requirements, of course, if it is High-end imported inverter, the problem should be small, with the domestic vector inverter, the frequency can also be full torque output;
Q:Inverter 0.2KW, the motor speed requirements down to 4 turn, the motor pole 4 pole. Can the drive drive the motor?
Can, but this is a test product, the application does not try!
Q:Siemens g120 inverter torque limit what is the meaning
For example, you have 100kg of power, but you can send the power and you lift the weight of the object, if the object weight of 10kg, you can only use 10kg of power.
Q:On the notebook power adapter output current and voltage issues
On the real virtual cable that adapter is rectifier filter output, no regulator, the notebook internal regulator, the adapter does not need to regulator. 3.25A is smaller than 4.5A, because the adapter has a power margin that can be used. Summer attention to touch the adapter surface is overheating. Conditional or buy a large number of good current.
Q:Delta VFD-A frequency converter motor number of poles set
According to the actual needs of the motor To provide the required power supply voltage, and then to achieve the purpose of energy saving, speed control, in addition, the inverter there are many protection features, such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, frequency conversion The device has also been very widely used.
Q:ASUS notebook power adapter can be universal? is it?
Under normal circumstances, as long as other ASUS notebook power adapter voltage, current and interface with your notebook the same, you can use. Not ASUS adapter even if the voltage, the interface is the same is best not to use, easy to cause damage to the computer. I suggest you can call the ASUS national service hotline to see, consult the current market can support your laptop adapter model, and then to the computer store or online purchase.
