浪涌抵制器(电子灭弧器)广泛应用于机械制造、化工、轻工、交换机、开关电路、数控机床、计算机控制CNC自动化生产线及CNC机床及配有电气控制各类调速系统设备中。

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.

在数控的各类系统中，它的外围线路中要有接触器、继电器和电机，而控制的最终对象是电动机在系统中接触器吸和瞬间继电器接点，往往由于触点引起火花、电弧，严重干扰到控制系统，使整个系统的波形发生畸变。同时在触点开闭时，会发生高压打火，造成接点损耗、变形、表面氧化、而损坏接触器。如果控制对象是数字电路或系统由计算机程序控制，那么原有程序会完全破坏使控制系统无法正常工作，甚至损坏集成电路。

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.

在各种继电器、接触器、所有感性负载、可控硅两端，在保护接点的电子线路中并联浪涌抵制器(电子灭弧器)组成一个滤波器，这就能有效的吸收由于接触器、继电器吸合、电机的碳刷而产生火花及电弧，使整个系统工作正常，同时也能延长接触器寿命，增强接点吸引力，可以有效地消除干扰，防止误动作，保护控制系统及计算机集成电路。

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.

产品适用于交流50/60Hz，电压至380V或直流电压至220V的电源电路中。用户在选用过程中只需根据被保护器件的线圈电压选择相应的电子灭弧器，与之匹配即可。

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.
