160 Ah Battery Backup Unit | GBU-4U
Product Information
The Guardian Battery Unit GBU-4U is a 48V 19” rack-mountable Lithium ion Battery Backup Unit (BBU) designed to be used in conjunction any modular DC Power System. The GBU Series of 48V batteries have been designed for data center and telecom applications as a replacement to Lead Acid batteries. This Modular Energy Solution can be scaled to meet any mobile switching center need.
The patented Energy Balance Technology (EBT) provides internal balancing among the BBU modules connected in parallel. The EBT ensures consistent voltage and current delivery from the entire system of connected modules, which maximizes runtime and power delivery. This technology allows the energy storage rack to be simple and self contained.
Remote management via the Modbus, over RS-485 or Ethernet via the Unipower GCC Controller with PowCom™ software provides immediate access to performance and alarm information. This interface is included with every telecom lithium battery and provides remote telecom battery monitoring.
Lithium Iron Phosphate (LFP) chemistry provides the longest life with over 3000 cycles and the lowest total cost of ownership.
