Emerson Edco SRA64 Series (One Pair Data/Signal Protection)
The Edco SRA64 Series surge suppressor is a single-pair cube implementing three-stage hybrid technology. This cube addresses overvoltage transients with gas tubes and silicon avalanche components. In addition, sneak and fault currents are mitigated with resettable fuses (PTCs). The PTCs increase resistance in several orders of magnitude when overcurrents exceed safe levels and resumes a normal state when overcurrents are removed. The ability to self-restore in this manner significantly increases suppressor performance and survivability.
The standard SRA64 Series second-stage clamps are placed from each signal line-to-ground. In certain cases, where ground potentials vary from site-to-site, a line-to-line only second-stage clamp may be preferred. This variation is specified by a suffix "D" on the part number. In other cases, line-to-line and line-to-ground second-stage clamps may be preferred. This variation uses an "X" suffix on the part number.
A variety of clamping voltages are available as standard. Reference the ORDERING INFORMATION section to ensure that a complete part number description is obtained.
