The Advanced Powerstrips (APS) provide premium quality, fireproof surge protection for PC and TV peripherals. They also reduce the amount of vampire / standby energy consumed by PC and TV peripherals. Each APS has inbuilt current sensing circuitry with 2 different switching thresholds to sense when a Control Device (typically a TV or PC) is On or Off / Standby and to then switch On / Off selected Outlets. Easy to install and provides simple automation to reduce wasteful standby energy consumption. Suitable for residential and workplace applications.
