KLD-BMS Series

Harmonic Protector

Harmonic control product developed for precise instruments on the user side that are susceptible to various kinds of interferences and result in various faults. It can absorb high-frequency pulse spike and high-frequency noise signals to protect sensitive equipment on the user side.

PRODUCT OVERVIEW

As science and technology continues to develop, harmonics generated by nonlinear modern power equipment and devices, such as computers, lighting control systems, communication systems, network control equipment, a variety of digital office equipment, light regulation and control systems, UPS, CNC machine tools, rectifiers, precise instruments, electronic control mechanisms, etc., result in a harsh harmonic environment, posing s great threat to the normal operation of the power system and equipment. The microprocessors in electronic equipment, automatic control equipment and computers are usually more sensitive and have higher requirements for harmonic environments.

KLD-BMS series harmonic protector can absorb harmonic interferences of various frequencies and energies. Eliminating the occurrence of harmonics at the source can automatically eliminate the random high-order harmonics and high frequency noise, pulse spike, surge and other interferences to the power equipment. Harmonic protector can purify the power supply, protect the power equipment and power factor compensation equipment, prevent the false tripping of the protection device, so as to improve the operation efficiency and reliability of the equipment, reduce the cost of equipment maintenance and repair, and prolong the service life of the equipment.

EFFECTIVE PROTECTION AGAINST
HIGH-FREQUENCY INTERFERENCE

●   Provide harmonic protection of various energies at frequencies of 1KHz-20MHz, eliminating high-order harmonics, high-frequency noise, pulse spikes, surges and other interferences.

●   Reduce the fault rate and misoperation of control equipment and other precise instruments to overcome the high-frequency interference caused by harmonic pollution.

●   Simple wiring, diverse installation positions, convenient commissioning, without routine maintenance.
