PS-R-V4-M

PowerShift® Macro V4 Main Shelf delivers the optimal voltage to your RRUs in real-time, automatically—regardless of power supply, distance, conductor size, or RRU power requirements. It optimizes backup power delivery by solving the voltage-drop problem. Inserted between the battery and trunk cable, PowerShift automatically senses and adjusts the battery’s voltage output to the power cable to compensate for the voltage drop. As the battery discharges, PowerShift continues to boost output to maintain the optimal input voltage to the RRU to increase battery backup time. PowerShift® V4 Main Shelf accommodates up to 3 boost modules (PS-2000-73) per 1RU shelf. There are 3 separate circuits per boost module for a total capacity of 9 circuits (RRU's) per 1 RU shelf. Each circuit provides a maximum output of 2,708 Watts at 73Vdc and has an integrated bypass function that automatically passes the input power through to the load connections in case of a circuit failure. After the controller (PS-CNTRL-V4) calculates the voltage drop in the power cable due to line resistance, each circuit delivers about 2,000W at 54Vdc to the RRH input. The V4 Main Shelf can be expanded by adding an extension shelve (PS-R-V4-S) to power up to 18 circuits (RRU's) in 2 Rus.
