Q:Laptop power adapter is broken, which brand is better domestic
This is usually very compatible with the power adapter brand, you can only buy the original, or to the local computer market with a similar output power adapter can be,
Q:Can the inverter stop intermittently during operation? If so, how to connect and set up
and the corresponding function of these terminals, you have to in the inverter Set up.
Q:The Schneider inverter reports the nlp command
Schneider inverter reported nlp ??? main circuit no electricity 1 re-power up 2 connected to the DC reactor terminals PO, PA / + between the short wiring, the main circuit can not be powered
Q:Asus notebook power adapter how to open
Can only be forced to open the pants and other things wrapped around the line on the line suggested that do not casually demolition
Q:Laptop power adapter bad what is the phenomenon?
Either the power is bad or the machine on the power supply module is bad to repair service
Q:380V 2 pole motor can use the inverter?
At the same time, the paint is thick, the best 2 times dipping Wiring with the end of the enameled wire end of the time, to use insulating materials separated better, more insurance
Q:How to choose the inverter
Look at the motor seat size is 7.5kw it, this model of the inverter manufacturers a lot of production, and are built-in brake unit, so in the function which are the same It is important that the inverter life, stability, price comprehensive consideration Mitsubishi, Panasonic, LG, Emerson, Yaskawa, Siemens and so on
Q:Inverter alarm a043, how is it
When there is a signal failure, if necessary, use DTI Board, if necessary, change P215 In addition, for the synchronous motor (P095 = 12): the inverter is released until the motor is at rest
Q:Laptop power adapter output voltage is not the same as the current? What's the effect?
so this replacement is generally feasible in the general use , But the remaining power supply power margin is very small, once your books took a lot of peripherals, such as two usb hard drive, and then cpu full speed operation, and then a base, the above to drive a full speed to read the disk, plus While charging the battery, it is estimated that the danger, and at any time to touch your power is not already already boiled eggs. 72w more than the 56w adapter 16w is to cope with this situation. So it is best not to use a small current instead of high current power supply
Q:Computer frequency changer to do cd frequency changer how points positive and negative
. In this circuit, the total capacitance is 6500 microfarads, the voltage is doubled.
