What is the difference between Emerson's inverter and power saver?
Many people have no clear details about the Emerson Inverter and Power Saver understanding. Power saver is generally divided into lighting fixtures and power saver. Using high-voltage filtering and energy absorption skills, the energy of the reverse potential of the high-voltage power equipment is actively absorbed, and the feedback is returned to the load, which saves the part of the electric energy from the high-voltage power grid. Here's a brief introduction to the difference between them. It is mainly introduced to you from six aspects.
Power Saver is different from Emerson's frequency converter mainly because:
1, frequency conversion technology is only one of many power saving technologies, including power saving technology including voltage limiting current limiting , power factor compensation, phase control power adjustment, frequency conversion, chopping, filtering, energy feedback and other technologies, even for the power saver using the frequency conversion principle, the frequency converter is only a unit in the power saver; Second, the development and design of Power Saver takes into account the various control requirements of the application site, with various control functions that facilitate field operation, such as temperature, pressure closed-loop control and other functions;
Third, in many industrial sites, direct wiring installation of the inverter does not meet electrical specifications, and it is easy to cause various safety accidents. Installing a complete set of power saver can reduce the occurrence of accidents;
> Fourth, the development and design of Power Saver fully considers the safety protection of the built-in inverter, set lightning protection circuit, overvoltage protection circuit and fault alarm function, to avoid accidental damage of the inverter itself.
5, according to the actual needs of the production site, the power saver generally built a high-performance bypass system, in the case of unexpected failure of the speed control unit, can still ensure the smooth progress of on-site production. 6. It is well known that the frequency converter generates certain harmonics during the working process. In many production sites, a large amount of harmonic interference often causes equipment malfunction and even damage, and research and development of the power saver. When designing, large-scale power-saving enterprises generally install harmonic filtering devices inside the power saver for the harmonic situation of the site, and filter out most of the harmonics in situ, which is crucial for the safety production of the customer. .
