Cost consciousness has become the consensus of all walks of life, it relates to business survival and success. For enterprises engaged in manufacturing, cost savings, reduce capital investment costs should first start. However, throughout the life cycle point of view, operating costs often exceed the cost of capital investment in the beginning.glue stick Therefore, careful analysis of machines and production facilities, energy needs, ease of maintenance, reliability and maintainability are the key to reducing costs.
The choice of drive technology is the focus of cost reduction,glue gun because the electric drive is the main energy-consuming devices in the control cabinet occupies a large space, renewable energy often require special cooling measures.
Especially for only a few kilowatts of small power rating applications, but does not drive the economy is often seen as the driving energy-saving solutions, and only need variable speed drives in their own technology or process within the. However, the market there are some products focus on the overall economic benefits of the drive, even in low-rated power applications.
Energy-saving effect.
To enable customers to visually see energy-efficient drive technology and life cycle costs of operating the impact of Beijing Benz has developed a floating electrical comparable conventional drive solutions and energy-saving solutions for DSP algorithm and its application, the algorithms and procedures will be clearly calculated and displayed for the user, how long after the recovery of relatively high capital investment costs. For the drive, the process only a few months time, after that, customers will be the investment income arising from savings in operating costs can.
"Energy efficient feedback" technology.
In general, the need for frequent changes in speed, transmission or load requires frequent changes to the electrical brake applications, the use of the drive is a good choice. For example, many devices use the occasion to send the drive can be used, including conveyors, elevators, cranes, transport vehicles, escalators and so on. In addition, the frequency with energy regeneration and other typical applications include pumped storage power station and wind power systems.
Previously required the use of active feedback or matrix converters can be fed to the power lines or potential mechanical energy, and because of cost considerations, only the standard driving tasks and / or lower power rated only for the use of such products. There is a new type of renewable energy technologies can overcome this shortcoming, this innovative solution not only has advanced technology, and more acceptable price, it said this technology is "efficient energy feedback" technology.
Intelligent loop from the basic principles and terms of significant cost savings.
Regeneration using the inverter with energy products in the engineering design stage to reduce costs. Electrical designers do not have to take into account the size, connectivity, cooling or braking resistor and other issues, the control cabinet no longer need to consider the installation of the braking resistor, the input reactor and its associated connections. And needs of local heat and waste energy braking energy compared with renewable energy control cabinet and power distribution room when the heat load lower. So many cases, without the use of temperature control system can not only save costs, and save space.
Renewable energy technology has a unique advantage: The "" inverter technology to produce capacitive reactive power to compensate for the vast majority of industrial environments inductive reactive power load, which do not have to use or less expensive to use reactive power compensation systems. In addition, because enterprises generally depends on the energy cost of reactive power - and thus reduce the reactive power, can significantly reduce their energy costs.
DC bus capacitors with smaller, reducing energy and reactive power exchange, because of its very low capacitance, so that the current power grid is very close to providing the ideal square wave shape, thereby preventing the lower order harmonics largely occurred, and low harmonic energy consumption is very high. Therefore, this function has the innovative renewable energy driving the current consumption of the traditional than the same power transmission will be as low as 25%. While such a converter can also help in the drive to save energy. Not only that: In many cases the size of connecting cables used by 23% will be reduced, thus facilitating the production facilities and the installation of the system, significantly reducing cable costs and the number of copper cables.
Low harmonic rectifier.
Compared with standard drive, the use of "energy efficient feedback" technology, the drive inverter harmonic content is much lower than the average, and below its 11 harmonic content much lower than the national grid standards. Feedback through the use of this energy efficient inverter, electronic design engineers do not have to worry about the place of traditional high-speed load changes occurring in the drive DC bus voltage spikes and overrun problems, this product can automatically intervene in the drive to compensate for these effects, The way the excess energy back in an instant network.
Under the same rated power at low energy.
As a result of a special circuit structure with the same power compared to traditional drive, even in the electric state could save more energy. At the same time it can be anti-braking energy back to power, on other occasions may be to reduce this energy cost. Coupled with the cost savings of braking resistors, saving installation space and reduces engineering and installation costs and inductive reactive power compensation, the innovative transmission products even at very low power rating is also excellent value for money.
Network can connect all kinds of use.
This product requirements and market average power inverter products, experience shows that this technology can be used around the world, but there is one exception: from independent generators not connected to the grid, you must use an external capacitor to eliminate resonance. This situation must be determined according to the special circumstances set the size of the capacitor.
"High energy feedback" technology is a new generation of products comes standard with the standard drive, so it can solve a variety of production / driver requirements. On the one hand it can be installed in the control cabinet (IP20) motor in or near (IP65), on the other hand, It can be used as a compact stand-alone drive (drive a motor) can also be used as a multi-axis drive unit ( simultaneously drive multiple motors drive modular units). According to actual demand, the series of drive products with integrated control functions and / or different input and output needs are available through the Siemens standard drive products are met.
"Efficient feedback" renewable energy technology advantages.
Energy Regeneration:
● sent back to the grid renewable energy.
● No use of a braking resistor.
● do not need installation, cooling and external components - while saving.

Low-low harmonic reactive power:
● No sharp wave current - but close to the ideal sine wave, which reduces the distortion reactive power.
● Low current consumption of about 25%.
● reduce the load on power supply system.
● use the cross-sectional area smaller feeder cable, reducing the cost of materials.
Reactive power compensation, improved power factor.
● reduce the input capacitance performance.
● Compensation motors and other inductive load connected to the grid reactive power.
● reduce the power system load, thus saving energy costs.
