Talking about the difference between frequency converter and power saver

Many people do not have a clear understanding of the specific differences and uses of frequency converters and power savers. The following is a brief introduction to the differences between them. Mainly from six aspects to everyone.

Power saver is different from frequency converter mainly because:

First, frequency conversion technology is only one of many energy-saving technologies. Power-saving technologies include technologies such as voltage regulation and current limiting, power factor compensation, phase-control power regulation, frequency conversion, chopping, filtering, and energy feedback. For the power saver using the inverter principle, the inverter is only a unit in the power saver.

Secondly, the R&D of the Power Saver considers various control requirements of the application site, and has various control functions that are convenient for on-site operation, such as temperature and pressure closed-loop control;

Thirdly, in many industrial scenes, direct installation of the inverter for wiring does not conform to the electrical specifications, and can easily lead to various safety accidents. The installation of a set of energy savers can reduce the occurrence of accidents;

Fourth, the R&D of the Power Saver fully considered the safety protection of the built-in frequency converter, and provided lightning protection circuits, overvoltage protection circuits, and fault alarm functions to avoid accidental damage to the inverter itself.

Fifth, according to the actual needs of the production site, the power saver is generally built-in high-performance bypass system, in the case of unexpected failure of the speed control unit, it can still ensure the smooth production of on-site production.

Sixth, as we all know, the inverter will generate certain harmonics during the work process. In many production sites, a large number of harmonic interferences often cause the devices to malfunction or even be damaged. When the R&D of the energy saver is designed, large-scale power saving is achieved. In general, companies will install harmonic filter devices inside the Power Saver to eliminate most of the harmonics on the spot. This is critical to the safety of customers.
