Overvoltage Protection & Power Conditioning

For Mains Powered, Communications Appliances


OVERVOLTAGE PROTECTION

A lightning strike or high voltage power disturbance can cause a Telephone System to fail by damaging components in its Communications Network, Power Supply and Central Processor.
This usually happens when an incident causes a over-voltage on, or between the Communication Cables, Mains Power Supply and Earth Cables of a building.

Over-voltage Protection will reduce the risk of damage from lightning strikes and power disturbances, and is achieved by the coordinated use of the following three items:

1. Communications Line Protection (multistage module).
2. Power Supply Protection (multistage module).
3. Earth Cable (to bypass surges).

A success rate above 90% can be expected from properly selected, installed and maintained protection equipment.


POWER CONDITIONING

An under voltage power disturbance such as a sag or brown-out can cause data corruption and can sometimes cause component damage. Telephone system and computer power supplies are at risk. A Standby Power Supply or Power Conditioner can solve this problem.

A power failure can last for a fraction of a second or for a number of hours and may cause data corruption or a long period without service. The importance of continuity of service will determine the solution; e.g., for a short outage that causes data corruption, data loss, or system lock-up, a Standby Power Supply is suitable; and, for mission critical equipment, an Uninterruptible Power Supply and additional Battery Cabinet will provide back-up power for a predetermined time.
