- 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:Do you need to rectify before switching?
- There are two ways to convert frequency, that is, cross and cross the intersection, the latter need a direct current, need no rectification, depending on your DC situation.
- Q:Lenovo laptop power adapter side of the feet which is positive
- Very simple, look carefully on the power there is a symbol on the map (relatively small, carefully looking for all the regular power above the standard), as I shown below is the positive external, most of the power is like this , If the sign on the icon is anti, that is connected to the center of the black point is negative, that is negative inside the positive. This figure is also very intuitive.
- 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:Quartet of the TA, TC terminals have positive and negative?
- The TC terminal has no positive and negative poles, which are passive programmable relays
- Q:How to view the parameters of the notebook power adapter on your computer
- Notebook power adapter using the correct method] 1. Try to avoid the use of outdoor or harsh environments to prevent the adapter is exposed or damp. 2. When you are not using the adapter, please unplug the power plug. Because, for a long time the power will let the adapter has been in working condition, will affect the end of life. 3. Although the adapter is a broadband operating voltage, marked from 100V-240V can be, but if the voltage is extremely unstable in the case of use, the same will cause damage to the power adapter.
- Q:Jd1a-40 motor speed controller and how to connect the motor
- First, variable pole alignment speed method
This method of speed control is to change the stator winding winding red method to change the cage motor stator pole pairs to reach the speed control target, the characteristics are as follows:
This method is suitable for production machinery which does not need stepless speed regulation, such as metal cutting machine, lift, lifting equipment, fan, water pump and so on.
Second, the frequency control method
Frequency control is to change the frequency of the motor stator power supply, thus changing the speed of its synchronous speed control method. Frequency converter system can be divided into exchange - DC - exchange converter and exchange - exchange inverter two categories, most of the current domestic use of cross - straight - cross frequency converter. Its characteristics:
This method is suitable for the requirements of high precision, better speed performance.
- Q:Oil-free vertical vacuum pump why a little negative pressure inverter on the torque limit
- and then use the inverter into three-phase AC, 380 volts almost, Can only use the transformer rose to 380 volts.
- Q:What parts of the inverter composition
- Simply put, the inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit
- Q:Is it possible to use a different laptop's power adapter?
- It is recommended to use the original comes with the adapter, different adapter output voltage is not the same
