Safecom's proven patented DPS Ver. 4 & Integrated Power Booster (Patent P) turn existing coax or power cable lines into dynamic super power highways that provide the most reliable and economic powering system and network backup solution. Safecom Smart Grid technology for powering & backup Cable TV networks DPS v4 Power Booster 4G

Based on the strategic placing of intelligent power management devices throughout the network, in the event of a power outage the DPS4 draws power from the nearest available source over existing coax or power cable. Utilizing breakthrough AC/AC stabilizing technology safecom's DPS4 + Power Booster ensure maximum voltage level – even over long distances. The concept

What is DPS- Ver 4 ? A two-way RF Pass 1GHZ passive device that toggles available power between two distant locations. Redirecting power from the "normally" remote powered area, to the area subject to power outage. During normal mode of operation, when there is no power outage at either end of the pair, the DPS v4 acts as power block to the other side.

DPS ver 4 – the new generation

Power Booster (Patent Pending) Increasing the powering area covered by power supply. The Power Booster solves the power distribution problem in a CATV network caused by high-resistance and low energy-efficient coax cables or power cables. The unit ensures the optimal voltage levels required in remote locations by fiber nodes, trunk amplifiers, and line extenders overcoming voltage drop along the power or coaxial able. t t Vout 84V +/- 6V Vin Vac 60Hz Vin 42-66V Vac 60HzVout 62V +/- 3V US Standard EU Standard
