[phone]
In many office and industrial locations, data lines (such as RS-232 and ethernet) and AC
power lines run in close proximity to each other, which often results in voltage spikes being
induced onto the data line, causing damage to sensitive equipment.
Protection Requirements
Data lines should be protected against overvoltages that can exceed 1500 V and surge
currents up to 50 A.
Data Line Reference Circuit
Figure 3.42 shows how a SIDACtor device is used to protect low voltage data line circuits.
