114 / 212 page  CATV Equipment http://www.teccor.com 3 - 26 © 2002 Teccor Electronics +1 972-580-7777 SIDACtor® Data Book and Design Guide CATV Equipment 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 (VDRM) is well above the peak voltage of the CATV power supply (90 VRMS Ö2), and the peak pulse current rating (IPP) is 3000 A.
