Product Specification

1U 4 Slot Inverter Expansion Shelf for Telecom Backup Power Systems

Overview for 1U Rack-Mounted Expansion Shelf

The EU-MSBS230H-8000VAN-1U is a 1U 4-slot inverter expansion shelf designed for 48VDC to 230VAC telecom backup power systems. It is used as an extension subrack for installing inverter modules in a telecom or network power platform where AC backup power is required.

This product is not a standalone inverter power system. It must be connected to a compatible main power shelf that includes the controller, breakers, distribution, and system management functions. When integrated with the host shelf, the EU-MSBS230H-8000VAN-1U provides a compact and scalable way to expand AC backup capacity for telecom cabinets, network racks, and communication sites.

With its 1U rack-integrated structure and 4-slot modular design, this expansion shelf is suitable for communication systems that need flexible inverter capacity growth while maintaining a compact cabinet layout. Based on your source text, the related inverter module is a 2000W class communication inverter module, so a fully loaded shelf can be positioned as supporting up to four compatible inverter module positions within the host system.

Key Features for 1U Rack-Mounted Expansion Shelf

The EU-MSBS230H-8000VAN-1U uses a 1U rack-mount design, making it suitable for telecom and network cabinets where installation space is limited. Its slim profile allows efficient use of cabinet space while supporting modular inverter deployment.

4-Slot Modular Configuration

This model is designed with 4 module slots for installing compatible inverter modules. It serves as a modular carrier for expanding AC backup capability within the telecom power system.

Designed for 48VDC to 230VAC Backup Power Systems

The expansion shelf is intended for telecom systems that use a 48VDC bus and require 230VAC backup output through inverter modules. It is suitable for communication cabinets, network nodes, and transmission sites that need uninterrupted AC support for key loads. The single-module source text describes a 48V telecom inverter architecture with 230VAC output functionality.

Works with Main Power Shelf

The EU-MSBS230H-8000VAN-1U does not include the controller or breaker section. It must be used together with a compatible main shelf, which handles monitoring, control, protection, and power distribution. This is a core point in your uploaded notes and should be reflected clearly on the website.

Scalable AC Backup Expansion

Because the shelf is built as an inverter expansion frame, users can increase AC backup capacity by adding compatible inverter modules according to site requirements. This structure is suitable for modular telecom power platforms that need flexible capacity planning.

Cabinet-Friendly Backup AC Solution

This product is intended for use in telecom and network cabinets that require integrated backup AC output without using bulky standalone inverter equipment. The uploaded material positions the related module for cabinet-based communication systems and backup AC scenarios.

Technical Specifications for 1U Rack-Mounted Expansion Shelf

Product Positioning for 1U Rack-Mounted Expansion Shelf

The EU-MSBS230H-8000VAN-1U should be positioned as an expansion shelf only, not as a complete integrated inverter system. In the actual system architecture, the main shelf provides:

• controller and monitoring

• circuit breakers

• protection and alarm management

• system distribution and coordination

This product mainly functions as a module carrier and expansion platform for adding inverter capacity to an existing telecom backup AC power system.

Typical Applications

• Telecom cabinets requiring integrated AC backup output

• Communication power systems with 48V battery bus

• Transmission and access network sites

• Outdoor or indoor network cabinets

• Edge communication nodes

• Industrial and utility communication systems needing modular backup AC supply

These application directions are consistent with the uploaded description of the related inverter module and the expansion-shelf use scenario.

Why Choose for 1U Rack-Mounted Expansion Shelf

The EU-MSBS230H-8000VAN-1U offers a practical and space-efficient way to expand backup AC capability in a telecom power platform. Its 1U compact design, 4-slot structure, and main-shelf integration architecture make it suitable for telecom operators and system integrators who need a modular solution for cabinet-based AC backup expansion.
