Q:Inverter problem
A: The inverter output 4 ~ 20mA (0 ~ 20mA), the analog signal can be directly connected to the measuring instrument, the daily design, installation, application are so, as long as the selection is correct, there will be no problem.
Q:My inverter is the era TVF8000 series, the motor is 15KW6 pole motor, has been used for 3 years.
Motor current when the current 10A this has no effect on you, the rated current is 31.4A, your inverter is selected how many W, is the fan pump type or universal? Now the motor operating current reached 34-35A, more than the rated current, then the motor may have two problems, one is the motor leakage powerful, and in a motor is overload, resulting in increased current
Q:What are the types of power adapter used in notebooks?
Notebook function is limited, such as power requirements of only 50-70 watts (W). In recent years, power requirements have risen above 100 W, but the expectations for weight and size have not improved accordingly. In addition, the need to meet the low standby power performance in the specification, external power (EPS) efficiency requirements and IEC1000-3-2 harmonic power requirements above 75 W make this challenge more difficult to deal with. This article explores new trends that enable power supply manufacturers to address these challenges and provide alternative solutions to choose from.
Q:ASUS and dell notebook power adapter can be universal?
One, not necessarily interchangeable. Need to compare the two adapter specifications to determine: 1, the books power adapter, there are 90W and 60W of the other, some products output voltage 19V and 14V of the other. "General" conditions, as long as the output power of the adapter is the same, the output voltage is the same (current may not consider), that is, their specifications are the same, you can directly substitute. 2, however, some foreign imports of products using 110V AC products, be careful to see clearly. 3, before the use of replacement, pay attention to observe if connected to the books of the power plug specifications are different, you can not directly insert. An interface adapter can be purchased. Can also be bad adapter plug, cut into the replacement adapter; Second, for example: 1, LITEON OEM products, parameters: input AC 100 ~ 240V 1.5A, output DC 19V3.42A. Rated output power 60W; 2, ASUS books supporting products, parameters: AC 100 ~ 240V 1.5A, output DC 19V 4.74A. Rated output power 90W.
Q:Whether the inverter can control the start and stop of the horizontal monopole centrifugal pump
Can be installed by a simple float level control to achieve, the general frequency is to constant pressure, of course, start and stop is completely controlable Oh. It's good for the pump to start the speed change
Q:The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!
1. submersible pumps are generally the problem, far away from the reflection voltage, the pump insulation breakdown, in particular, to better pump. 2. Distance away, the inverter and pump connection thicker. 3. Then on the output filter.
Q:In the case of the inverter, why can not the normal operation after removing the gearbox? The motor is 4 pole.
If there is a load, it may be less than the torque. So it can not run.
Q:How does the variable frequency motor output torque at very low frequencies?
1, to improve the slip of the inverter compensation coefficient 2, to improve the continuous lifting coefficient of the inverter, but the coefficient is too high there will be overcurrent. 3, with no sensor vector control can increase the motor output torque or encoder with the vector control can make the motor at low frequency to achieve the rated output torque.
Q:Please recommend a high performance laptop power adapter?
See what model you notebook ah, according to your power adapter voltage, rated current to match.
Q:11kw 6-pole motor can be used to adjust the inverter to 1800RPM?
Frequency converter in the 5-50Hz is constant torque frequency, 50-100Hz is constant power frequency, to see what you want to get the effect
