What this product is

What this product is

This equipment acts as the core AC distribution hub for telecom base stations and edge data centers, responsible for safe power distribution, branch circuit protection, and lightning surge suppression.

What problem it solves

Effectively resolves common site issues such as chaotic power distribution, lack of multi-way fine-grained branch control, vulnerability to lightning surges, and absence of remote power alarm monitoring.

Who and where it is for

Widely applicable to standard telecom base stations, indoor distributed server rooms, outdoor integrated cabinets, micro-stations, and edge computing nodes.

Core advantages

  • High Integration: Built-in 63A main breaker with 12 independent MCB outputs for precise multi-device power distribution.
  • Class C Surge Protection: Integrated high-performance surge protection module effectively shields against lightning and grid spikes.
  • Reliable Alarm Integration: Equipped with dry contact alarm outputs for real-time fault reporting to environment monitoring systems.
  • Carrier-Grade Build: Flame-retardant, high-strength structural design seamlessly fits standard 19-inch racks and outdoor cabinets.
