- Q:Delta inverter reported CE4 reasons? Casually asked how many kinds of CE under a total
- If the Delta C2000_M is the Modbus drive can not handle Not to the official website under the manual
- Q:ASUS notebook power adapter can be universal? is it?
- ASUS notebook power adapter is not universal, depending on the model, the output voltage and current requirements are different, select the battery and consistent adapter. Note: different brands of laptop batteries may be different, so do not use, through the laptop battery voltage and current comparison power adapter voltage and current to judge. If the voltage and current are roughly the same can be used.
- Q:The relationship between the power supply of the notebook and the battery
- 2, when the laptop turns on the power adapter, and the battery power is low, the charging circuit detects the battery power is lower than the set value, the power adapter will side of the host power supply, while the battery charge. After the charge is restored, it is restored to the power supply state directly from the adapter. Therefore, the relationship between the power supply of the notebook and the battery is that the battery is charged by the power adapter when the battery level is below the set value.
- Q:Siemens g120 inverter torque limit what is the meaning
- Torque is a strain, the inverter can not actively control the output torque size, only according to the size of the load demand torque, the output of the corresponding torque.
- Q:Laptop warranty period is not over, the power adapter is broken, repair money?
- Look at your reinsurance period if not in the warranty period is not man-made damage can be changed or for the change
- Q:Three-phase asynchronous AC motor speed control method
- Third, cascade speed control method Cascade speed regulation refers to the winding motor in the rotor loop into the adjustable additional potential to change the motor slip, to speed control purposes. Most of the slip power is absorbed by the additional potential in series, and the additional device is used to return the absorbed slip power to the grid or to convert the energy. According to the slip power absorption and utilization, cascade speed can be divided into motor cascade speed, mechanical cascade speed control and thyristor cascade speed form, the use of thyristor cascade speed, which features: Can be transferred in the speed of the process of slip loss back to the grid or production machinery, the higher efficiency; Device capacity and speed range is proportional to the investment province, for the speed range of 70% -90% of the rated speed of production machinery; Speed ??control device failure can switch to full speed operation, to avoid shutdown; Thyristor cascade speed power factor is low, the greater the impact of harmonics. This method is suitable for use in wind turbines, water pumps and rolling mills, mine hoists, extruders.
- Q:Notebook power adapter on how to look at power
- It should be noted that there are many in Japan to buy a notebook or over there in the parallel imports, input only support 110V in China is not used, because the Chinese standard is 220V. Now the subject is 90W 20V. Output voltage and power will be identified, such as the target for the 90W 20V, that output power is 90W, the output voltage is 20V. If only the output voltage and output current are identified,
- Q:Is the laptop power adapter hot?
- Third, the power of the nominal voltage than my books the battery voltage is much higher, not an accident, right? First of all, to know is that the power supply to the books and the battery power supply to the notebook is different. Battery-powered, the battery output is pure DC, very clean, the battery voltage is neither possible nor need to design a high, lithium battery chemical properties determine a cell output voltage can only be about 3.6V, so Many batteries are used in three cascade way, 10.8V also became a very popular battery voltage. Some batteries are slightly larger than the integer value of 3.6V, such as 3.7V or 11.2V, etc., in fact, to protect the battery. Power supply, the situation is more complex, first of all need to add voltage to further regulation filter to ensure that the power performance is not very good in the case of stable work, the voltage regulator after the two parts of the city, all the way to the work of the power supply , The other way to the battery charge to the part of the power supply to the battery when the same power supply, and the part of the battery charge through the battery charge control circuit can be added to the battery, the control circuit can be very complex, so the power The voltage must be greater than the cell voltage to have sufficient capacity to supply the charge control circuit to the units. Finally the voltage actually added to the cell will never be the nominal voltage of your power supply. Rest assured.
- Q:Speed regulation method of three - phase asynchronous motor
- 1, frequency control, with the inverter, power 2, change the magnetic pole logarithm, not feasible. 3, stator series resistance, energy consumption
- Q:What is the common COM point of the PLC and the inverter? Is it positive?
- It depends on your PLC and inverter I / O is what type, the most simple can be divided into two kinds of NPN and PNP, NPN COM point is negative, PNP COM is positive.
