Q:Is the laptop power adapter AC and DC?
Most laptop power adapters can be used for 100 ~ 240V AC (50 / 60Hz). Basically, most of the notebook computers are external power supply, with a power cord and the host connection, which can reduce the size and weight of the host, only a very small number of models built in the host power.
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:What is the frequency of `30 points
AC are frequency, China is 50 Hz, is in a second amplitude of 50 times. To change this frequency, it is necessary to use some electronic components to change the current frequency. General frequency conversion for the tributary motor speed more. So that some equipment can be stepless. Principle, see the first floor just fine, copy the more detailed.
Q:Inverter principle eff23
Low-voltage general-purpose inverter output voltage of 380 ~ 650V, the output power of 0.75 ~ 400kW, the operating frequency of 0 ~ 400Hz, its main circuit are used to pay straight to pay the circuit. Its control has gone through the following four generations. 1U / f = C sine pulse width modulation (SPWM) control mode is characterized by simple control circuit structure, low cost, mechanical properties of hardness is better, to meet the general requirements of the smooth transmission speed, has been in various fields in the industry Widely used. However, this control mode at low frequencies, due to the lower output voltage, the torque by the stator voltage drop is more significant, so that the maximum output torque reduction.
Q:Inverter ACS355 If the speed is outside the allowable range, how to set the limit value
1. Set 2002 MAXIMUM SPEED Defines the maximum permissible speed.
Q:My laptop can not use the power adapter, and can only use the battery, how is it ah,
I have encountered the same problem, plug in the adapter, or use the battery power, the battery alarm, not the battery charge, the power adapter can not be used. But the power can charge the battery. If the power adapter alone, one will automatically shut down. Measure the adapter voltage normally. And then to get the computer city maintenance department, gymnastics, it is a simple question, the original power line in the circuit board on the solder joints are loose, that is, Weld, resulting in insufficient current, no wonder, off the machine can charge, boot can not charge, It shuts down. Spent 100 yuan. Business really black. I saw the repair. On the welding a few times OK. No wonder, once I suddenly shot about, the adapter can be used. Later, how to shoot not work. However, although spent 100, but my computer's heat silicone grease for the whole, the computer CPU temperature is not so high before. The beginning of the maintenance staff said that the power management chip may be broken, if the bad to more than 100, then, no bad, just contact the problem, welding also received me 100, really depressed. In fact, you can say good, if the contact problem, certainly below 100.
Q:Three-phase asynchronous AC motor speed control method
First, variable pole alignment speed method This method is to change the way to change the stator winding red way to change the cage motor stator pole to achieve the purpose of speed, the characteristics are as follows: With a hard mechanical properties, good stability; No slip loss, high efficiency; Wiring is simple, easy to control, low prices; A level of speed, large difference, can not get smooth speed; Can be used with the regulator speed, electromagnetic slip clutch used to obtain a more efficient smooth speed control characteristics. This method is suitable for production machinery that does not need stepless speed regulation, such as metal cutting machine tools, lifts, lifting equipment, fans, pumps and so on.
Q:Does the inverter set the number of poles to match the number of poles of the motor?
The number of motor poles corresponds to the speed of the motor, the number of poles is not set when the speed of the control error, in the high speed requirements of the transmission is not allowed.
Q:Variable frequency conversion frequency difference characteristics based on,
Frequency conversion is better, you can smoothly change the synchronous speed. Change the difference is relatively poor, also known as "energy consumption slip" speed. Synchronous speed unchanged, the slip rate has changed, so the speed changed.
Q:Variable frequency pump pressure in the very low flow instability, why?
. If you want to stabilize the pressure, you must adjust the pipeline characteristic curve is the work point to enhance, so that you can both stabilize the pressure and adjust the flow.
