Product Description

Features

frequency changer or frequency converter is an electronic device that converts alternating current (AC) of one frequency to alternating current of another frequency. The device may also change the voltage, but if it does, that is incidental to its principal purpose.Traditionally, these devices were electromechanical machines called a motor-generator set.

Q:Inverter problem
A: The inverter output 4 ~ 20mA (0 ~ 20mA), the analog signal can be directly connected to the measuring instrument, the daily design, installation, application are so, as long as the selection is correct, there will be no problem.
Q:Notebook plug in the power adapter lights, but can not open the machine
1. Remove the power adapter and battery, the host does not power the case, hold down the boot button does not move, keep the notebook 30 seconds to release the residual static electricity; 2. Connect the power adapter separately to try to power on; 3. Connect the battery separately to try to boot; 4. If conditions permit, you can plug the memory test.
Q:What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
Electronic governor is the use of control thyristor conduction angle to change the motor supply voltage, the motor characteristics of the curve down to change the speed of asynchronous motor. Its characteristics are as follows: the motor speed adjustment range is small, low speed when the motor load capacity is poor, the speed decreases, the motor torque decreases, not applicable with constant load, when the speed is low, prone to stall phenomenon; Applicable to fan load. Inverter speed is to change the frequency of the motor to achieve the AC asynchronous motor speed adjustment, speed adjustment balance, the motor load characteristics do not change with the speed change, suitable for load adjustment and constant torque adjustment. Excellent performance, but the cost is higher.
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:How to choose a power adapter
With the seller to an output 20V ,, 0.5A IBM single hole power adapter
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:Variable frequency pump pressure in the very low flow instability, why?
From the performance curve, the flow becomes smaller, the combination of pressure and frequency adjustment flow will only stabilize the flow at a small value, the pressure will be reduced, because the work point will move down.
Q:Yasukawa inverter reported bb code that is the reason why the base blockade?
This should be the meaning of the drive block, that is, the drive signal is locked, there is no drive signal, and start a frequency change but no voltage output, you find someone to repair the circuit board can be used normally, this is generally the circuit board Problem, the module is less likely to be bad
Q:What is the frequency converter used to do, why some motor with the inverter?
Frequency converter is widely used in the speed regulation of AC motor.Varameter speed control technology is an important development direction of modern power transmission technology, 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.
Q:Is the number of Amps of the notebook power adapter higher than the original number of security on the computer?
Sure answer, no! Rest assured with it, but be careful not to buy the cottage goods, this on the computer and security is not good. good luck!
