浪涌抵制器(電子滅弧器)廣泛應用于機械制造、化工、輕工、交換機、開關電路、數控機床、計算機控制CNC自動化生產線及CNC機床及配有電氣控制各類調速系統設備中。

Surge resistance (E-ARC) is widely used in machine building, chemical industry, light industry, switches, switching circuits, numerical control machine tools, computer-controlled CNC, and CNC machine tools, speed control system equipment with electric control device.

在數控的各類系統中，它的外圍線路中要有接觸器、繼電器和電機，而控制的最終對象是電動機在系統中接觸器吸和瞬間繼電器接點，往往由于觸點引起火花、電弧，嚴重干擾到控制系統，使整個系統的波形發生畸變。同時在觸點開閉時，會發生高壓打火，造成接點損耗、變形、表面氧化、而損壞接觸器。如果控制對象是數字電路或系統由計算機程序控制，那么原有程序會完全破壞使控制系統無法正常工作，甚至損壞集成電路。

In numerical control system, the  peripheral circuits contains contactor, relay, and motor. The ultimate object of the motor system is to control the transient-absorption between contactor and relay contact, causing serious disturbance to the control system, and leading the whole system to waveform distortion due to the spark and arc caused by contact.when the contact open and close, it happens to High-voltage spark, damaging he contactor by causing contact loss, deformation, surface oxidation. If the object is a digital circuit or system controled by computer program, the original program will completely undermine, the control system does not work, even damage the integrated circuits.

在各種繼電器、接觸器、所有感性負載、可控硅兩端，在保護接點的電子線路中并聯浪涌抵制器(電子滅弧器)組成一個濾波器，這就能有效的吸收由于接觸器、繼電器吸合、電機的碳刷而產生火花及電弧，使整個系統工作正常，同時也能延長接觸器壽命，增強接點吸引力，可以有效地消除干擾，防止誤動作，保護控制系統及計算機集成電路。

At the two sides of various relays, contactors, and all perceptual load, SCR, add a parallel surge resistance (E-ARC) in the circuit of protection contact to composite a filter, it can effectively absorb the sparks and arcing, so that the whole system can work normally, and also extend the life of contactor, strengthen the attraction contacts, effectively eliminated interference, preventing the miss actions, protecting the control system and the computer integrated circuit.

產品適用于交流50/60Hz，電壓至380V或直流電壓至220V的電源電路中。用戶在選用過程中只需根據被保護器件的線圈電壓選擇相應的電子滅弧器，與之匹配即可。

The scope of application:

The product is applicable to the power circuit whose AC frequency is 50/60Hz, and the voltage is 380VAC or 220VDC. In the selection, the E-ARC should be chosen according to the coil voltage of protection devices, which is match to the filter.
