Picture of High Voltage 6KV Converter Frequency
- Q:Inverter problem
- (0 ~ 20mA), but the main input / output is completely isolated, than the output of the inverter simulation of the output of the analog output The amount of signal impact resistance, anti-interference ability.
- Q:I power adapter output current 3.25A for a 4.5A, can you use it
- Can provide a large current that the rated power is higher than the original landlord that can be assured that the use of the best, but the original oh a lot of cottage performance instability do not burn the notebook
- Q:ASUS and dell notebook power adapter can be universal?
- I can not remember to insert into the ah. The Looks like DELL that interface is very special
- Q:400w 6-pole motor should be equipped with much of the inverter?
- 0.75KW just fine, neither waste the inverter resources, but also to meet the occasional overload. And 0.75KW inverter is the standard model.
- Q:18: 5 kilowatts bipolar multi-pole pump motor with inverter
- If you worry about the small, with 18.5KW is far enough.
- Q:What is the motor series parameter setting of the inverter? If it is with the spindle,
- The motor series setting of the inverter should be set according to the series of motor
- Q:How does the spindle drive system of the inverter realize the positive and negative control of the main pole?
- Communication can reach a longer and more stable, generally better of the city 485
- Q:What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?
- Soft starters and frequency converters are two completely different uses of the product. The frequency converter is used for the need for speed control where the output not only changes the voltage but also changes the frequency; the soft starter is actually a voltage regulator for the motor to start when the output only changes the voltage and does not change the frequency. The frequency converter has all the soft starter functions, but its price is much more expensive than the soft starter, the structure is much more complex. Soft starter (soft starter) is a set of motor soft start, soft stop, light load energy saving and a variety of protection functions in one of the new motor control device, known as the Soft Starter abroad. The softener uses a three-phase anti-parallel thyristor as a voltage regulator, which connects it between the power supply and the motor stator. This circuit, such as three-phase full-bridge rectifier circuit. When using the soft starter to start the motor, the output voltage of the thyristor gradually increases, the motor gradually accelerates until the thyristor is fully conductive, the motor works at the mechanical characteristics of the rated voltage, smooth start, reduce the starting current and avoid starting the overcurrent trip. When the motor reaches the rated speed, the start-up process ends, the soft starter automatically uses the bypass contactor to replace the completed thyristor, providing the rated voltage for the normal operation of the motor to reduce the heat loss of the thyristor and prolong the service life of the soft starter , To improve its efficiency, but also to avoid the harmonic pollution to the grid. Soft starter also provides soft stop function, soft stop and soft start the process of reverse, the voltage gradually reduced, the number of revolutions gradually reduced to zero, to avoid free-wheeling caused by the impact of torque. How the frequency converter works
- Q:What is the maximum speed adjustable for a 4-stage motor with a rated frequency of 50Hz / 60Hz?
- Can be transferred to the rated frequency of 2 times, but to filter the mechanical characteristics of the motor and motor running time, to filter into the motor fever.
- Q:HP laptop power adapter how to open
- HP notebook power adapter for the full size of the design, you can follow the following steps to dismantle:
1, notebook computer power adapter for the injection molding package or with a strong adhesive glue, without any screws, so generally only with violence to crack. However, as long as the method properly, after the dismantling of the power adapter can be restored to the original, do not carefully observe almost no traces of open.
2, the power adapter on the side of the side of the white paper, with an electric knife edge along the power adapter between the gap between the cover, and then hit the electric knife with a hammer, so that the electric knife from the adapter between the upper and lower cover
go with. In the different positions of the gap between the upper and lower covers of the adapter, use the tip of the electric knife to be scratched along the gap. When the upper and lower covers are first split, the depth of the tool is deep and then the upper and lower covers of the adapter are separated.
3, then open the shell of the power adapter, you can see the adapter circuit outside the package with a copper shield, with a knife to cut the shielding tape on the tape, and then use the soldering iron shield and the internal circuit board connected to the two Solder joints, you can remove the shield.
4, between the shield and the circuit board is also separated by a layer of thick plastic film, and then cut off the knife after the United States, you can see the circuit board "Lushan true"
