Industrial grade with ient voltage suppression protector Compatible with RS-422, RS-485 standard, can convert single-ended PCI-E signal to RS-422/RS-485 signal, with fast ient voltage suppression protector, this protector is designed to protect RS- 422/RS-485 interface, using TVS ient voltage suppressor, 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 across both ends is clamped at a predetermined value to protect subsequent circuit components from damage due to ient high voltage surges. This protector can effectively suppress ESD, provide 600W surge protection power per line, as well as surge voltage and ient overvoltage generated on the line due to various reasons, and the small inter-electrode capacitance ensures that RS-422 /RS-485 connection high-speed mission.<br><br>Colour:As Shown Material:PC+metal<br><br>Package Contents: 1 x Expansion Card<br><br>Only the above package content, other products are not included.
