Q:How to view your own laptop power adapter is how much tile?
There are signs on the power adapter, you look for sticky paper to write the voltage and current power. If there is no write power, the direct voltage multiplied by the current is the maximum power.
Q:How to choose the right inverter?
Inverter selection science or not for the normal operation of the frequency conversion system is essential. Many beginners on the general inverter selection method is not enough understanding, or even know the method, not sure the choice of the inverter model is positive solution, the following for everyone to solve the mystery. Inverter selection first look at the AC motor. Because the frequency conversion system generally first determine the motor, then select the inverter. In principle, it is necessary to determine the inverter model based on the actual current at which the AC motor is operating for a long time, and not on the motor nameplate. Inverter selection next depends on the load type. Frequency conversion system driven load equipment can be divided into three types: constant torque load, constant power load, fan, pump load, different load type select the inverter model is different.
Q:Can the notebook's power adapter be mixed?
This is a 90W power adapter This is Acer's 65W power adapter Here need to explain: General in the power adapter only shows the output voltage and current, not marked wattage, need to calculate their own. The value obtained by multiplying the number of voltages and the number of currents is the wattage. More on notebooks Related topics: Notebook forums hope that the above information is helpful to you
Q:First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
In the inverter in the following 18.5kw inverter will bring their own braking unit for some special occasions, such as the inverter at high speed due to production needs, must be 1 second, or less time to stop, in the stop when the frequency The internal DC bus voltage is too high, the inverter will be reported over-voltage fault, in the positive and negative connected bk-dk connected to a resistor to the inverter discharge, the inverter will not report over-voltage failure
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.
Q:Whether the inverter can control the start and stop of the horizontal monopole centrifugal pump
Can be installed by a simple float level control to achieve, the general frequency is to constant pressure, of course, start and stop is completely controlable Oh. It's good for the pump to start the speed change
Q:How can a variable speed multi - speed three - phase asynchronous motor be controlled by a frequency converter?
With the inverter control, then you do not need multi-speed motor, because the inverter can directly control the motor speed, if the two together, the formation of a waste.
Q:Do not the laptop directly connected to the power adapter?
3, the notebook internal circuit using low-voltage direct current work, if the direct use of 220V AC and its connection will burn the circuit in the low-voltage devices, which is absolutely prohibited, but also basic common sense. At the same time, its external power jack is also dedicated, and the AC outlet is different;
Q:What is the maximum speed adjustable for a 4-stage motor with a rated frequency of 50Hz / 60Hz?
Can be transferred to the rated frequency of 2 times, but to filter the mechanical characteristics of the motor and motor running time, to filter into the motor fever.
Q:On the laptop power adapter problem
Can be simply calculated; 19 * 4.74 = 90.06 90W 19 * 3.42 = 64.98 65W Obviously, the second is a virtual standard, can not be used It is not enough power, ranging from the adapter burned, while the motherboard is like other notebook hardware damage, unpredictable. The adapter is likely to burn after the high and low voltage to the notebook board burned the situation more common. My notebook is dell original 4.62A, when playing the game are very hot.
