UT-7912 is a PCI-E to two-port RS-232 serial card, which can convert single-ended PCI-E signals to RS-232 signals, with a fast transient suppression protector, which is designed to protect RS- 232 interface, using today's advanced TVS tube, under normal circumstances, the TVS tube is in a high resistance state. When the TVS tube is subjected to an instantaneous high-energy shock, it can reduce the impedance at both ends at a very high speed and absorb a large current. Therefore, the voltage across the two ends is clamped to a predetermined value, and the subsequent circuit elements are protected from damage due to transient high voltage shocks. This protector can effectively suppress lightning (LIGHTNING) and ESD, provide 600W lightning surge protection for signal lines, as well as surges and transient overvoltages generated on the lines due to various reasons, and the extremely small inter-electrode capacitance Ensures RS -232 high-speed transmission.
