Q:ABB frequency converter and the difference between domestic frequency converter
Both the eyepiece and the objective lens are convex lenses with different focal lengths. The focal length of the convex lens of the objective lens is smaller than the focal length of the convex lens of the eyepiece.
Q:How to choose a power adapter
With the seller to an output 20V ,, 0.5A IBM single hole power adapter
Q:The relationship between the power supply of the notebook and the battery
1, when the notebook battery is fully charged, and connected to the power adapter, usually by the adapter directly to the host power supply, this time the battery is idle, the adapter power supply without battery conversion.
Q:How do I protect the inverter when the three-phase two-pole motor is running?
Three-phase two-pole motor running inverter protection, should be based on the protection of tips, check the corresponding manual to deal with. When the inverter protection has a corresponding protection tips (such as over-current, over-voltage, speeding, stall ... ... etc.), the product manual will generally give the corresponding protection tips. According to these measures to check, deal with, you can solve the problem.
Q:Whether the inverter can control the start and stop of the horizontal monopole centrifugal pump
Inverter general control object is the AC motor, you are the AC motor, then the general inverter will be able to achieve start and stop, select a reasonable power section, a reasonable set of start and stop time can be very good drop protection motor. Can also achieve speed control function.
Q:Why the number of motor poles increased, the inverter capacity will increase
The relationship between the motor current and the power is The power is equal to the current and voltage of the product again good with the power factor. (Simplex)
Q:How to view the parameters of the notebook power adapter on your computer
Notebook power adapter using the correct method] 1. Try to avoid the use of outdoor or harsh environments to prevent the adapter is exposed or damp. 2. When you are not using the adapter, please unplug the power plug. Because, for a long time the power will let the adapter has been in working condition, will affect the end of life. 3. Although the adapter is a broadband operating voltage, marked from 100V-240V can be, but if the voltage is extremely unstable in the case of use, the same will cause damage to the power adapter.
Q:90KW inverter start 90KW, 4-pole motor and 6-pole motor j What is the difference? The inverter can be used for it?
Three-phase AC induction motor, 4-pole speed is generally 1480 rpm, 6-pole speed was 980 rpm
Q:What is the adapter?
Easy to join the Electronics (China) Co., Ltd. to sell the type of adapter and the purchase of different adapters:
Q:Laptop power adapter output voltage is not the same as the current? What's the effect?
I would like to elaborate on the basic principle of the large standard current power supply can replace the small standard current power supply. Some friends have misunderstood, that a large nominal current power will burn books, because the current big thing. In fact, how much current in the same voltage depends on the load, that is, the work of the books, when the books of high-load operation, the current larger, the books into the standby time, the current is smaller, in short, On the voltage divided by the equivalent resistance of the books. Large nominal current power supply has enough current margin, will not be replaced by a small standard current power supply after the overheating or output voltage is too low. On the contrary, with a small current power supply instead of high current power on the existence of the above risks. But some friends with 56w power supply instead of 72w with no problem, because the power adapter is usually designed to leave a certain margin, the load power should be less than the power supply,
