Telephone and Cable Applications for Surge Protection
- Phone lines are the most sensitive lines to inductive surges as they are generally the least insulated.
- Our phone and cable protection utilizes solid-state technology that creates the path of least resistance to ground.
- Phones operate at a standing voltage of 48VDC, ringing voltage 95-105VDC.
- When induction becomes present on a phone line and reaches .150 milliamps, a reset-able sneak fuse takes it off and keeps it off until the line is clear. It will self-reset when the line is clear.
- Our residential phone protection clamps at 130VDC.
- Installation – Our unit is small in size, you can place it in the network interface (phone) box outside the house. It is a bi-directional unit, just split the phone wire and place one end in one side of the unit and place the other end in the other side of the unit. It then has a screw terminal on top for the ground wire. The unit itself is weatherproof, but if you have exposed copper from your splicing, cover it with silicone.
- We manufacture a cable surge protectors, the SYC-VF-H
- The VF-H is tuned specifically for high frequency and broadband signals.
- The cable protection products are hybrid units. They are very labor intensive to make and have to be hand tuned so there will be no insertion loss.
- The surge current capability is 20,000 amps and clamps at 52VDC.
- Our units will not affect the signal.
- Installation – Install this unit at the network interface (cable box), it is bi-directional and weatherproof.
- The warranty on both the cable and the phone protectors is lifetime.
