The ET48100-P5E21 is a 1U 2-slot solar expansion shelf designed for -48V telecom power systems. It is used as an extension subrack for integrating high-voltage photovoltaic DC/DC modules into a telecom power platform.
This unit is not a standalone power system. It must be connected to a compatible main power shelf that includes the controller, breakers, and system management functions. When used together with the host shelf, the ET48100-P5E21 provides an efficient and space-saving way to expand solar input capacity for telecom and communication power applications.
With its compact 1U design and 2-slot configuration, this expansion shelf is suitable for telecom cabinets, hybrid energy systems, and outdoor communication power solutions where modular PV expansion is required.
The ET48100-P5E21 adopts a 1U height design, making it suitable for telecom power systems where rack space is limited. Its compact structure supports modular installation and flexible system expansion.
This model is configured with 2 module slots, allowing installation of two compatible high-voltage solar DC/DC modules. It is designed as an expansion platform for increasing PV conversion capacity within the host system.
The ET48100-P5E21 is intended for -48V telecom DC power architecture and is suitable for communication sites that require photovoltaic energy integration.
This product is positioned as a high-voltage DC/DC expansion shelf, used for connecting PV input modules to the telecom power system. It is suitable for solar-assisted communication power solutions and hybrid telecom energy platforms.
The ET48100-P5E21 does not include the main controller or breaker section. It must be used together with a compatible main shelf that provides system control, monitoring, protection, and power distribution.
By adding this expansion shelf to the main telecom power system, users can increase solar module capacity in a simple and structured way, making the system easier to scale according to site demand.
