SCONI-AR-MODN避雷器MODEM ARRESTER
General - The lightning arrester series SCONI-AR-MDM are commonly used to protect sensitive telecom equipment such as communication line and data transmission lines form damage caused by transient surge voltages that typically result from lightning strikes or equipment switching operation. - This model adopts Polyswitch, TVS (Transient Voltage Suppressor) and GDT (Gas Discharge Tube) Which are placed in front of, and in parallel with, the Sensitive device acting as high impedance component While not influencing the signal in normal operation. - Polyswitch devices are used to help protect against harmful over current surges and over temperature faults. Like traditional fuses, these devices limit the flow of dangerously high current during fault condition. The Polyswitch device, however, resets after the fault is cleared and power to the circuit is removed, there by reducing and repair costs. - This model protects linked devices via twisted-pair cables from lightning surge damage which induced in cables. - RS-422 and RS-485 use. - 3 stage protection structure. - CE conformity.
