We are on the road to 5G, and cell site infrastructure is quickly evolving to meet those needs. Notably, 5G-friendly radios require more power at the top of cell towers. A voltage drop between the power system at the tower’s base and the radio at the top can trigger a shutdown of the remote radio head before the equipment provider’s backup battery fully discharges.
As a solution, the Vertiv eSure™ C48/58- 1000 Power Extend Converter economically boosts voltage up to - 58 VDC to support the increasing power needs of remote radio heads on cell towers. The compact device – small enough to fit in the palm of your hand – plugs into an existing DC distribution panel in the same position as a singlepole bullet circuit breaker, conserving usable space.
The eSure Power Extend Converter consumes 0U of additional rack space, in contrast to traditional converter solutions which consume up to 4U of rack space. We estimate you could save hundreds of dollars per site in installation costs alone. Along with space and CapEx reductions, the eSure C48/58- 1000 conserves considerable energy while performing above 98% efficiency.
Multiple units can operate in parallel to support radios requiring up to 3kW of input power. Vertiv has developed a calculator to help operators determine the number of converters required to power the radios at their site and how to position the devices optimally in the distribution panel.
The eSure Power Extend Converter saves space and energy, while enabling reliable and efficient cell site operation. The solution can ensure that businesses who rely on 5G for critical operations aren’t interrupted by a shutdown. Instead, they can have continuity through a fast and affordable technology upgrade.
