Growing Equipment and Power Requirements at Telecom Sites : 76U Double Cabin Cabinet Integrates Equipment and Power and Batteries

Why Should Outdoor Telecom Sites Reassess Cabinet Space?

As telecom base-station configurations become more complex, outdoor cabinet selection is no longer simply a matter of choosing an appropriate external size. Telecom equipment, power systems, and batteries need to be arranged within limited outdoor space while maintaining practical access for maintenance and cable routing.

For these applications, key outdoor telecom cabinet selection factors include rack capacity, internal structure, power-system configuration, and battery installation space. The ET15075200A-38U uses a double-cabin structure with 2 × 38U of 19-inch standard rack space, providing a total of 76U for telecom equipment and supporting power systems.

How Can 76U of Rack Space Support Equipment Integration?

A 2 × 38U Configuration Enables Equipment Planning

The ET15075200A-38U provides two 38U sections using 19-inch standard racks. For outdoor sites that need to accommodate telecom equipment together with supporting power equipment, this double-cabin configuration provides a defined basis for rack-space planning.

The cabinet measures 1500(W) × 750(D) × 2000(H) mm, including a 150mm-high base. The datasheet also states that the dimensions can be customized.

During equipment selection, engineers should calculate the required rack height, equipment depth, quantity, and maintenance access rather than relying only on the total 76U figure.

How Should Power and Batteries Be Included in Space Planning?

Integrated 6kW Rectifier and 6kW Solar Systems

In addition to telecom equipment space, the cabinet integrates a 6kW rectifier system and a 6kW solar system. The ET48200-M5K45 power sub-rack uses a 19-inch standard rack-mounting format and has a height of 5U. Both the rectifier and solar systems consist of 2 × 3kW modules.

Cabinet planning therefore needs to account for telecom equipment, the power sub-rack, distribution circuits, and cable routing. The datasheet specifies that cables enter and exit from the bottom of the cabinet, which should be considered during project planning.

Battery Dimensions Are Also Critical

The ET15075200A-38U includes six sets of LiFePO4 batteries, each rated at 48V and 200Ah. Each battery measures 442 × 520 × 244 mm and weighs 79.3kg.

For an outdoor power cabinet, battery selection involves more than energy capacity. Installation dimensions, weight, maintenance access, and cable connections also need to be considered. Procurement and engineering teams should therefore verify battery dimensions alongside the Ah rating.

How Does Cabinet Structure Affect Maintenance?

The ET15075200A-38U uses a front-maintenance design with two front doors, inner hinges, and an anti-theft three-point locking system. The cabinet enclosure uses 1.2mm galvanized steel sheet, while the racks use 2.0mm galvanized steel sheet.

This configuration integrates equipment installation, front-side maintenance, and physical security into the cabinet structure. For an outdoor telecom site, the required door-opening area and maintenance access should still be verified against the actual installation location.

Conclusion: Move From Rack Capacity to Overall Space Planning

For outdoor telecom sites with multiple equipment and power requirements, selecting an outdoor power cabinet should involve a combined review of rack capacity, power equipment, battery dimensions, cable routing, and maintenance access.

The ET15075200A-38U provides 76U of total rack space, a 6kW rectifier plus 6kW solar system, and six 48V/200Ah LiFePO4 battery sets. These defined specifications provide a basis for planning integrated telecom equipment and power-system installation.
Final configuration should be determined according to actual equipment quantity, rack-unit requirements, battery installation method, cable routing, and site maintenance conditions.
