FAQ

How to choose a Siemens inverter for a 5.5KW three-phase motor (2 pole)?

Power, voltage, frequency, and you can use torque sensors to measure torque

The notebook power adapter flashes

1: Check the socket with a multimeter is normal, the supply voltage is 220V. If the utility voltage is not normal, it is recommended to replace the use of environmental testing. 2: Check with the multimeter whether the output voltage and current of the power adapter match the label. If the gap is very large, and the mains voltage is normal, you can determine the power adapter failure, need to replace the laptop power adapter. 3: If the above check is normal, remove the laptop battery, do not external adapter. Press and hold the notebook power button 5 seconds to repeat 3 times. After releasing the notebook residual charge, insert the power adapter separately, power on the test. 4: If the fault persists, check the notebook's power connector, whether the exception. Such as loose or the appearance of damage and so on. 5: the above checks are normal, basically can be a preliminary judgment is the notebook motherboard failure. Recommended repair service station.

The laptop's power adapter is broken how much it costs

Buy a new, new price of dozens to one hundred. Notebook adapter, as long as the output current is greater than the old, the same voltage, with the brand can be interchangeable, Different brands of adapters to meet the above requirements, that is, insert the notebook connector is different, you can use scissors + tape,

ABB frequency converter and the difference between domestic frequency converter

The objective lens is equivalent to the lens of the projector, the object is inverted through the objective lens, magnified real image. Eyepiece is equivalent to the ordinary magnifying glass, the real image through the eyepiece into a positive, magnified virtual image.

Laptop power adapter is used to do what

The laptop's power adapter is a device that converts 220V AC power from a power supply unit to a low-voltage direct current device for powering a laptop. Power adapter output low-voltage direct current into the computer, but also through the computer motherboard power circuit to further deal with, resulting in 1.8V, 3.3V, 5V and other sets of voltage for memory, CPU and other components to run; another power adapter to provide the power can also be related Charge control circuit to charge the battery for the laptop.

I power adapter output current 3.25A for a 4.5A, can you use it

Can provide a large current that the rated power is higher than the original landlord that can be assured that the use of the best, but the original oh a lot of cottage performance instability do not burn the notebook

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

Why the notebook power adapter can not be universal

Third, the current is different Different brands of laptop power adapter current is not the same, for example: under normal circumstances IBM is 4.5A, Dell is 3.34A, Hp is 2.7A, Sony is 4.1A and so on. In fact, the same brand of laptop power adapter voltage and current are not the same. So, even if the same brand of notebook computers channeling with power adapter to confirm the voltage and current specifications.
