As cable providers enter the local exchange market, protection of CATV 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 over-voltages that exceed 6000V
and surge currents of up to 3000A. CATV station protectors should be able to
withstand over-voltages that exceed 5000V and surge currents of up to 1000A. The
SIDACtors chosen in Figures 3-25 through 3-28 meet these requirements.
Applicable Regulatory Requirements

Power Inserter and Line Amplifier Reference Circuit
Figures 3-25 & 3-26 show how the P1900ME SIDACtor is used to protect line
amplifiers and power supplies versus using Teccor
s patented circuit that requires two
SCRs and one SIDACtor (Figure 3-27). The P1900ME is used because the peak off-
state voltage (V
DRM
) is well above the peak voltage of the CATV power supply
(90V
RMS
2) and the peak pulse current rating (I
PP
) is 3000A.
