Q:Can the HP laptop's power adapter be universal?: If the power adapter socket is the same as the output voltage can be common. But there are a few places to note, HP notebook power adapter output voltage there are many, the most common 19V and 18.5V, but even if the output voltage is the same, the output current may be different, that is, the output power is not the same , If your notebook needs a larger input power, then you have to use the match can be, the lower power may not make the battery normal use, and even harmful to the battery.

Q:What parts of the inverter composition: Frequency 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. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply and other fields. However, due to the environment, the use of life and man-made operation and other factors, affecting the life of the inverter greatly reduced, while the use of a variety of failures have occurred. Here we are on the composition of the inverter and common problems and countermeasures and we discuss. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.

Q:Can the laptop 1.3a power adapter be used on a 1.5a device?: Absolutely can not try 1.5a! If you want your laptop to go wrong, then use it!

Q:What is the laptop adapter: 4, the working principle: the use of unstable power supply switching power supply principle through the conversion circuit into the notebook computer needs constant voltage DC, to the laptop computer power supply and charging; it is worth noting that: this conversion circuit, there must be protection circuit (Overcurrent protection circuit, overvoltage protection circuit short circuit protection circuit, etc.), to prevent accidents, the protection of the laptop will not burn.

Q:30 kW 6 pole frequency motor torque is how much: To know what is the use of ah, the inverter motor is the same with the ordinary motor, but to prevent the operation of a low speed plus a fan

Q:Laptop power adapter current is not the same alternative?: The adapter is the voltage source, the actual output current depends on the size of the load resistance,

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:East yuan 7200GS inverter start 11KW 4-pole motor and 2-pole motor need to modify what parameters?: If you use the environment is relatively poor, it is recommended that you use Austrian St. sealed inverter, this inverter can be moisture, dust, water, oil, corrosion.

Q:Can the notebook's power adapter be mixed?: At present, the market sales of notebook power is generally 90 watts and 65 watts two, using integrated graphics, or configure the low-end notebook, usually 65 watts. Using the independence was, the configuration of high-end, or the game audio and video of this, are generally 90 watts. If the laptop's power adapter is damaged can not be used, it is best to repair the department as soon as possible to repair. If it is for emergency, before using the two adapters to check the output power and current and voltage are conceded, as the adapter input current and voltage is not the same, should be the general household voltage is 220V, so almost all of the notebook power The adapter is 100-240V ~ 1.5A words, as long as the output current and voltage values, and wattage equal, and then one is the same interface, you can mix. In general, the voltage is stable, the output wattage is the same, the notebook is basically no harm.

Q:How to lift Yaskawa inverter base blockade?: Unlock the base block of Yaskawa inverter: 1. If the Yaskawa inverter reported that the base blockade, we should first check the cause, parameter settings in strict accordance with the recommendations of professional engineers to set.
