The DMW series voltage and frequency stabilized power supply produced by our company is designed and developed specifically for the power supply voltage and frequency of the power grid are unstable, the voltage is seriously deformed, there are flicker, drop and other comprehensive voltage quality problems, which are used to protect the precision electrical equipment with relatively high requirements for the power grid. The power supply adopts advanced high frequency pulse width modulation (SPWM)IGBT inverter technology, the internal use of AC and AC circuit design structure, equipped with a special power frequency isolation transformer, safe and reliable, completely clear the grid interference, pure output waveform, with voltage stability, frequency stability function at the same time very high precision, light weight, small size and so on.
1.Purchase a solar charging controller that matches the system requirements before installation. 2.Choose the right installation location, avoid installing it in a place that is wet, hot or exposed to direct sunlight, and consider reliable heat dissipation and good ventilation. 3.Perform the correct wiring operation according to the installation instructions or the electrical drawings provided by the manufacturer to ensure that there is no short circuit or poor contact. 4.Depending on the battery type and system requirements, set the parameters correctly to protect the battery and optimize charging efficiency. 5.Ensure that the grounding connection of the solar charging controller is reliable and meets the national or regional safety standards. 6.Regular maintenance and monitoring are required after installation.
The whole circuit of the variable frequency power is composed of AC - DC - AC - filter and other parts, so its output voltage and current, waveform are pure sine wave, very close to the ideal AC power supply. It can output grid voltage and frequency of any country in the world. The frequency converter is composed of AC - DC - AC (modulated wave) and other circuits, and the standard name of the frequency converter should be frequency conversion governor. The waveform of the output voltage is a pulse square wave, and the harmonic components are many, the voltage and frequency change proportionally at the same time, can not be adjusted separately, does not meet the requirements of AC power supply, in principle can not be used as a power supply, generally only for the speed regulation of three-phase asynchronous motors.
Deming's AC power source is designed with the technical conditions of GB7260, GJB181, GJB325, digital frequency division, phase locking, waveform instantaneous value feedback control and other new technologies and modular structure, with good output waveform quality and strong load adaptability; it has passed the inspection of the State Quality Supervision Bureau and has been widely used in the production of power electronics, medical, aviation and other industries and scientific research.
Recently, a batch of advanced 3KW 48V wind turbine controllers were successfully delivered to Sweden. As a key component of the wind power generation system, this product has the function of monitoring and controlling the operation of the wind turbine. This wind turbine controller uses advanced technology and efficient wind energy management capabilities to achieve stable fan operation, maximize wind energy efficiency, and precisely control power generation.
Abstract: In recent years, the rapid development of renewable energy has spawned the need for energy storage systems to balance energy supply and demand and maximize the use of sustainable energy sources. In this context, single-phase energy storage inverters have emerged and become an important part of renewable energy storage. This news will give a brief introduction to the single-phase energy storage inverter.
Developments in the clean energy sector have been seeking new ways to improve the efficiency of renewable energy use. In recent years, as an innovative technology, Wind solar hybrid controller has been widely concerned. The technology can realize the collaborative utilization of wind and light energy, which brings greater development space for the clean energy industry. The following describes the function description, installation diagram, precautions and application scope of the wind solar hybrid controller.
In recent years, the development of clean energy field has been concerned. As an important part of renewable energy, wind energy has become the first choice for many countries to pursue sustainable development. In wind power generation, the wind turbine yaw controller, as a key technology, provides a guarantee for the best performance of the fan under various meteorological conditions.
The on grid wind turbine system is composed of wind turbine, on grid controller, on grid inverter, metering device and power distribution system. Wind energy is converted into AC electrical energy by the wind turbine, and then converted into DC electrical energy by the on grid controller, and then DC electrical energy is converted into AC electrical energy of the same frequency and phase as the grid by the on grid inverter, and part of the power is supplied to the local load. Surplus power is fed into the grid.
