FL485, RS485 Signal Surge Protector
Introduction
FL485 signal surge protector is designed by IEC61000-4-5 and ITU-TK20&K21 standard. It adopts multilevel protective circuit and the newest high-speed surge protection device which has quick response, low residual voltage output and excellent transmission performance. The interface adopts standard industrial terminal blocks which is easy to use and suit for all lightning protection in RS-485 communication field. FL485 signal lightning protector is designed and manufactured on the principle of discharge, limited current, clamping, stabilivolt. When signal wire gets an overvoltage and overcurrent shock, it will put lightning power or its jamming signal into the ground. Overvoltage restriction enables electrical equipment to operate safely within allowable range. This product adopts metal housing and good sealing, which has anti-dust and anti-corrosion function. It adopts serials connection that can restrain high voltage pulse on the wire to prevent backend device from being damaged by lightning and industrial surge. It can be widely used in remote control and transmission of security monitoring device, digital public broadcast system, water/electricity/gas meter of intelligent community, instrument and all kinds of fields that use RS-485 industrial bus control.
