Product Description:

Product Introduction

High-voltage frequency converter based on H bridge series units. High voltage inputs directly. In order to save energy, phase-shifting transformer inputs the low voltage on the second side to each power unit of H bridge and the output series of each phase and all power units connect so it has formed high voltage to drive the motor that. It’s a high-tech, green energy-saving product integrating advanced automatic control technology, high-power electric and electronic technology, fast and reliable fiber communication technology, high voltage technology and digital signal processing technology.

Q:Is the speed of the motor controlled?
Change the external conditions, you can change the motor speed: 1. Change the number of pole pairs of the motor. (Multi-pole motor use) 2. Use the frequency converter to change the frequency speed 3. Winding motor rotor series resistance speed control. 4. Slip motor is to change the slip electromagnetic speed
Q:Laptop power adapter is used to do what
The laptop's power adapter is a device that converts 220V AC power from a power supply unit to a low-voltage direct current device for powering a laptop. Power adapter output low-voltage direct current into the computer, but also through the computer motherboard power circuit to further deal with, resulting in 1.8V, 3.3V, 5V and other sets of voltage for memory, CPU and other components to run; another power adapter to provide the power can also be related Charge control circuit to charge the battery for the laptop.
Q:The laptop's power adapter is broken how much it costs
Notebook adapter only for the general repair 50-100 new general 150-250
Q:B2b frequency how to speed
can be seen from the formula: frequency f changes, the speed will follow the change. 2) When the motor connected to the public grid, you can use the inverter (2) When the motor is connected to a single motor, you can change the output frequency of the generator directly to change the output frequency of the generator. Change the frequency of the power supply to the motor to change the speed of the motor.
Q:Is the laptop power adapter AC and DC?
Notebook power adapter is not AC and DC. Power adapter is a small portable electronic equipment and electrical and electronic power supply conversion equipment, generally by the shell, power transformers and rectifier circuit, the working power for the exchange (China AC standard AC 220V), according to its output Types can be divided into AC (AC) output type and DC (DC) output type. General notebook power adapter are DC output, is the exchange of DC conversion equipment.
Q:Jd1a-40 motor speed controller and how to connect the motor
Third, cascade speed control method Cascade speed regulation refers to the winding motor in the rotor circuit in the adjustable additional potential to change the motor slip, to achieve the goal of speed. Most of the slip power is absorbed by the additional potential in series, and then an additional installation occurs, and the absorbed slip power is returned to the grid or converted to the energy. According to the slip power absorption application method, the cascade speed regulation can be divided into the motor cascade speed regulation, the mechanical cascade speed regulation and the thyristor cascade speed regulation situation, take the thyristor cascade speed regulation, Suitable for fans, pumps and rolling mills, mine hoists, extruders on the use. Fourth, winding motor rotor series resistance speed control method Fifth, the electromagnetic speed control motor speed method Six, hydraulic coupler speed control method This method is suitable for fan, pump speed.
Q:Can the laptop's power adapter be used for years?
In the power adapter has a nameplate, marked above the power, input and output voltage and current and other indicators, with particular attention to the input voltage range, which is the so-called "travel power adapter", if the city voltage to only 110V country , This feature is very useful, and some parallel notebook computers are sold only in the origin, there is no such compatible voltage design, or even only a single 110V input voltage, in our 220V mains voltage will be burned to burn.
Q:What is the base blockade in the drive?
After the base is blocked, the power tube is fully closed to protect the power tube.
Q:I have a 11KW-4 pole inverter, now with the 4KW-4 pole motor, what impact?
11KW the following can be brought, the inverter rectifier module may be broken,
Q:Computer frequency changer to do cd frequency changer how points positive and negative
Two identical capacitors in series, the capacity is half of the original, the two capacitors in parallel after the same capacity doubled.
