6 Frequently Asked Questions about “Base station power cabinet rectifier module configuration”
How many rectifier modules are available?
Individual rectifier modules with an output of 2000 W are available for creating complete power supply systems. The 19" 1H carrier can accommodate either five 48 V / 2000 W rectifier modules combined with a monitoring and control unit (SLIMLINE controller) or six rectifier modules.
How many rectifier modules can fit in a 19 H Carrier?
The 19" 1H carrier can accommodate either four 48 V / 3000 W rectifier modules combined with a monitoring and control unit (SLIMLINE controller) or five rectifier modules. This gives a power rating of 12 kW or 15 kW per rack.
What RF modules can be used in a base station?
A base station can be configured with single-mode RF modules of GSM, UMTS, and LTE and multimode RF modules to support any single mode as well as two or three modes including GSM, UMTS, and LTE. RF modules working in different frequency bands can be used together to support multi-band applications.
How many types of rectifier are required?
Only one type of rectifier is required for systems within a power range of 3 kW to 300 kW. This simplifies stock management and logistics for the benefit of the owner as it is only required to keep one type of module in stock for all systems.
How many lbbp boards can be configured in a base station?
The number of LBBP boards to be configured in a base station that supports LTE depends on the number of cells, bandwidths, antenna configurations, and the number of CPRI ports to be supported by the base station. Each BBU working in LTE mode needs to be configured with at least one LBBP and each LBBP supports six RF modules.
How many cabinets can a apr48 have?
System configurations include single cabinets offering up to 20kW, or two cabinets suited together to permit up to 40kW of output power. The core building block of the system is the APR48-3G rectifier module or, for superior operating efficiency, the APR48-ES “Energy Saver” module.
