Perfect Power Output Section
The HIVERT general MV VFD adopts the power cells connected in series and voltage overlapping method (i.e. Power cells multi-level cascade technology), it can output the perfect PWM sinusoidal waveform (see Figure 2 and Figure 3). It has the following advantages:
1. No need for the additional output filter
2. Directly driving general synchronous or asynchronous motor
3. No de-rating operation on the motor
4. No dV/dt stress on the insulation of motor and cables
5. No torque ripple, extending service life of motors and mechanism
6. No cable length restriction within the acceptable voltage drop.
The general MV VFD has the following protection functions and features:
Overload and over-current
Phase loss and grounding
Over voltage
Overheat
Current limit
Redundant control power supply

- Q: Laptop power adapter repair how much money
- Different notebook power adapter models are different, the price gap is large. ? Maintenance costs to see the specific model and damage level position. Generally do not recommend maintenance, it is recommended to replace the more appropriate. If you are not covered by the warranty period, you can repair free of charge. Hands-on ability to recommend self-repair, pay maintenance department recommended. After all, once again a greater chance of damage.
- Q: What is the number of parameters of the motor frequency of the Siemens inverter?
- Different types of Siemens frequency changer pole pair parameters different. 6SE70 is p109; The following is the p109 parameter description: P109 * Motor #PolePairs 109 For the synchronous / asynchronous motor input motor pole pairs of the function parameters. If the rated frequency (P107) and rated speed (P108) change, automatic calculation This parameter, if necessary, checks and verifies this parameter. note: - for some of the pulsed encoders (P130 = 11, 12, 15, 16) The maximum number of pole pairs of P109 = 15 can be achieved - P109 must be written when the write function (P060 = 6) is implemented. - Automatic calculation of the pole pair on the motor with regenerative feedback on the rated data Number to be added. Where the function map: 360.2, 361.2, 362.2, 363.2, 364.2 ? MM4 series is r313, which is calculated by the input rated frequency and rated speed calculated read-only value, must be selected in the p3900 to calculate the correct value. You can also set pole pairs by p314. ? S120; G110; G120; G130; G150; S150 with MM4 series.
- Q: The laptop power adapter is burned
- Upstairs that are almost, I said two points: First, the landlord said the problem I really met, you can still use the power adapter, nothing, little effect, nor is the machine's problem, but still suggest that you have time to hold your machine to the computer shop test under. Second, the battery you do not use the first, directly with the power adapter, as you said, so as not to two conflicts, your battery broke. On the power adapter, if you want to buy, you directly search ADP-90SB BB, for the best is the best.
- Q: Inverter signal line analog 4-20mA connection positive and negative can be reversed?
- Analog input signal is particularly vulnerable to external interference, so the general use of twisted shield as a signal line; and wiring as short as possible, generally not more than 20 meters; if some use conditions are vulnerable to external serious interference, the analog signal Side need to add a filter capacitor or ferrite core.
- Q: ASUS notebook power adapter can be universal? is it?
- Under normal circumstances, as long as other ASUS notebook power adapter voltage, current and interface with your notebook the same, you can use. Not ASUS adapter even if the voltage, the interface is the same is best not to use, easy to cause damage to the computer. I suggest you can call the ASUS national service hotline to see, consult the current market can support your laptop adapter model, and then to the computer store or online purchase. If you feel that my answer is satisfied, please adopt Wo take
- Q: Laptop power adapter bad what is the phenomenon?
- Either the power is bad or the machine on the power supply module is bad to repair service
- Q: Can the inverter be used to control the speed of the DC motor?
- The inverter can be used to control the speed of the DC motor. Inverter control DC motor is to control the DC motor. Inverter is the application of frequency conversion technology and microelectronics technology to change the AC power frequency and effective voltage power control equipment. The frequency converter is usually used to control the AC motor. Inverter at work can change the AC power frequency and effective voltage, another point of view, is the inverter in the control output (injected into the controlled device) AC frequency, but also control the output of the effective power. A DC motor is a rotating electric machine that converts DC power into mechanical energy. DC motor coil in the current must be in accordance with certain changes (commutation) can be rotated, according to the principle of commutation DC motor can be divided into brush and brushless motor two categories.
- Q: Is the number of Amps of the notebook power adapter higher than the original number of security on the computer?
- Sure answer, no! Rest assured with it, but be careful not to buy the cottage goods, this on the computer and security is not good. good luck!
- Q: How to make the motor speed (control speed), can not use frequency
- If you use AC asynchronous motor speed control in three ways: 1 / variable speed control. By changing the motor stator pole pairs to speed, not the linear speed for the sub-file speed, the motor structure and electrical control more complex. 2 / electromagnetic speed control. Driven by the magnet magnet, the electromagnetic coil through the variable size of the DC to speed, for the linear speed, but a waste of energy 3 / frequency control. Through the inverter speed, stepless speed regulation, speed control effect is good, but one-time investment. If the DC motor speed is to change the armature or the excitation coil voltage to achieve speed. Application in the relatively high demand, a one-time investment is relatively large
- Q: Why G120 inverter to be equipped with 4-pole motor?
- On the upstairs that the motor parameters to be set on the possible, such as voltage, current, power, power factor, rated efficiency, rated frequency, rated speed, motor overload factor
