Many people don't have a clear idea of the detailed differences and uses of AC converters and power savers. Power savers are generally divided into lighting appliances and power savers. The high-voltage filtering and energy absorption skills are used to automatically absorb the energy of the reverse electric potential of the high-voltage power equipment, and continuously feedback back to the load, saving the part of the electric energy drawn by the electrical equipment from the high-voltage power grid. Here's a brief look at the differences. It is mainly introduced to you from six aspects.
The main reasons why power savers are different from frequency converters are:
First, the frequency conversion skill is only one of many power-saving skills, including voltage regulation and current limiting, power factor compensation, phased power regulation, frequency conversion, chopping, filtering, energy feedback and other skills, even if the power saver using the principle of frequency conversion is concerned, the frequency converter is only a unit in the power saver;
Second, the development and planning of the power saver takes into account the various control requirements of the application site, and has various control functions that are convenient for on-site operation, such as temperature, pressure closed-loop control and other functions;
Third, in many industrial sites, the direct wiring device of the inverter does not conform to the electrical specifications, which simply causes various safety incidents, and the complete set of power savers can reduce the occurrence of incidents;
Fourth, the development and planning of power saver fully considers the safety protection of the built-in inverter, and sets up lightning protection circuit, overvoltage protection circuit and fault alarm function to avoid accidental damage to the inverter itself to the greatest extent.
Fifth, according to the practical needs of the production site, the power saver generally has a built-in high-performance bypass system, which can still ensure the smooth progress of on-site production in the case of unexpected problems in the speed control unit.
Sixth, as we all know, the inverter will occur in the process of working a certain harmonic, in many production sites, a large number of harmonic disturbances often cause equipment malfunction and even damage, in the development and planning of the power saver, large power-saving enterprises will generally be for the harmonic situation of the site, in the power saver internal device harmonic filtering device, in situ to filter out most of the part of the harmonics, which is very important for the safe production of the customer.

The inverter has no short-circuit protection for the reason – Reynolds
Short-circuit maintenance is a function of equipment connected between the power supply and the load, which can effectively disconnect the short-circuit point from the power supply when the load side is short-circuited. If an equipment has a short-circuit maintenance function, it must have a certain short-circuit breaking ability; And a device with the ability to break in a short circuit ...

How to determine the frequency of start-up – Reynolds
Generally, most motors start to speed up from 0Hz, but in some special cases, it is necessary to start directly from a certain frequency. At this time, the frequency output of the VFD at the moment of activation is the activation frequency. In general, you need to set the activation frequency in the following situations.

The reason for using frequency conversion speed regulation - Reynolds
Variable frequency speed regulation can be used in most motor drag occasions, because it can provide accurate speed control, so it can easily control the rise, descent and variable speed operation of mechanical transmission. The use of frequency conversion can greatly improve the efficiency of the process (the variable speed does not depend on the mechanical part) and at the same time ...

Heavy load generally refers to the long time of energy storage balance when the equipment load inertia is large and needs to be turned on, that is, the time of start-up.
2. The requirements for working current are not ...
