Q: How do you prevent current and future Power LIne Carrier Signal Blockage?

A: Specify AC Electronics electronic ballast. The AC Electronics electronic ballast has Carrier Guard� Power Line Carrier Protection System. Eliminate PLCS problems before they start! Carrier Guard features two AC Electronics designed and manufactured Super Shield� inductors which: 1. Shield power lines from the ballast circuit. 2. Share a common magnetic core allowing inductors to "talk" to each other and prevent signals from escaping to the power lines and interfering with other systems.

Q: What are Power Line Carrier Signals?

A: Power Line Carrier Signals (PLCS) are signals sent on power lines that run throughout buildings. These signals communicate information from one electrical circuit to another. This is the latest technology and the future in automation and control systems that link computer server networks, clocks, HVAC and lighting through building management systems.

Q: What are the potential problems a ballast can cause to Power Line Carrier Signals?

A: The Simplex Clock system is a prime example of how Power Line Carrier Signals work. Simplex Clocks are installed in many school and office buildings. It is designed so that a master clock communicates and is synchronized with every clock in the building through PLCS. If the ballast you install in your lighting fixture does not have proven PLCS protection circuitry, it can actually "eat" or block the signals, which will shut down every PLCS system in the building. This has happened and can cost hundreds of thousands of dollars in ballast replacement costs. Doesn't it make sense to avoid this problem before it happens?
