As cable providers enter the local exchange market, protection of CATV (Community
Antenna TV) equipment becomes even more critical in order to ensure reliable operation of
equipment and uninterrupted service.
Protection Requirements
CATV line equipment should be able to withstand overvoltages that exceed 6000 V and
surge currents up to 5000 A. CATV station protectors should be able to withstand
overvoltages that exceed 5000 V and surge currents up to 1000 A. The SIDACtor devices
illustrated in Figure 3.32 through Figure 3.35 meet these requirements.
The following regulatory requirements may apply:
• UL 497C
• SCTE IPS-SP-204
• SCTE Practices
• NEC Article 830
Power Inserter and Line Amplifier Reference Circuit
Figure 3.32 and Figure 3.33 show how the P1900ME SIDACtor device is used to protect
line amplifiers and power supplies versus using two SCRs and one SIDACtor device
(Figure 3.34). The P1900ME is used because the peak off-state voltage (V
above the peak voltage of the CATV power supply (90 V
rating (I
