Overview

 

Communication Components, Inc. Twin AC/DC RRU Power Supply provides a Universal AC Power alternative to  power most –48 VDC Remote Radio Heads and other auxiliary outdoor equipment operating on –48VDC. The RRU Power Supply is a highly efficient convection cooled power source and as such does not require any internal or external fans for normal operation. The heatsink is integrated into the Power Supply housing and provides adequate convection cooling in outdoor ambient environments.  The Power Supply enclosure and input and output connectors are completely weather sealed making it suitable for outdoor deployment in all environmental conditions. High reliability and high efficiency make the Twin AC/DC RRU Power Supply an ideal solution for both indoor and outdoor AC powered applications.

 

Technical Description:

The Twin Universal AC to DC RRU Power Supply provides a nominal -48 VDC output and a maximum (absolute) of -54.5 VDC. The single line DC output configuration supports a load of up to 24 ADC and the dual line DC output configuration supports up to 14 ADC per line continuously. The input voltage can vary from 85 to 265VAC (47-63 Hz) while maintaining continuous operation under all rated load conditions.
The RRU Power Supply is power factor corrected with a minimum power factor rating of 0.95. The power supply utilizes a highly efficient power converter circuit achieving typical efficiency in excess of 88% at 70% rated load. Noise and ripple are kept below 4V peak-to-peak under all load conditions.
Both overcurrent (OC) and overvoltage (OV) protection are built into the RRU Power Supply to prevent damage to the power supply with an automatic recovery feature. The overcurrent circuit will trigger between 105% and 140% of rated load and the overvoltage will trigger between 60-69 VDC. Both will conditions will automatically recover, upon an AC power cycle, provided the OC and OV conditions have been cleared.
The Power Supply is fully weather sealed and the housing is IP67 rated, making it suitable for all outdoor environmental conditions. The provided output connections are IP55 rated, 12 AWG cables (dual DC output) or 8 AWG cable (single DC output), 2 wire with exposed pigtails for custom termination.
