CAT IV protection is required whenever a connection is made to the high voltage line or a utility line. So where the line connects to an electric meter, the run between the meter and panel, or to a motor, CAT IV isolation is required. High level of isolation is also required in the extremely noisy environments of welding equipment. This 5 slide presentation introduces the CNY6x High Voltage Isolation Optocoupler series featuring 12000V peak overvoltage protection for your CAT IV applications. Run Time 05:40
