product descrtion

Industrial grade with transient voltage suppreion protector

Compatible with RS-422, RS-485 standard, can convert single-ended -E signal to RS-422/RS-485 signal, with fast transient voltage suppreion protector, this protector is designed to protect RS- 422/RS-485 interface, using TVS transient voltage suppreor, when both ends of the TVS tube are subjected to an instantaneous high-energy shock, it can reduce the impedance at both ends of the TVS tube at a higher speed, absorb a large current, and thereby reduce its voltage. The voltage acro both ends is clamped at a predetermined value to protect subsequent circuit components from damage due to transient high voltage surges. This protector can effectively suppre lightning and ESD, provide 600W lightning surge protection power per line, as well as surge voltage and transient overvoltage generated on the line due to various reasons, and the small inter-electrode capacitance ensures that RS-422 /RS-485 connection high-speed transmiion.
