What this product is

What this product is

The system incorporates an AC surge protective device (SPD), digital active power factor correction (APFC) circuit, high-frequency isolated DC-DC resonant power stage, integrated DC power distribution unit (PDU), and an intelligent monitoring supervisory controller. It orchestrates real-time parameter tracking, battery charging/discharging algorithms, and bus voltage regulation to feed wireless baseband, radio, and auxiliary telecom equipment safely.

What problem it solves

Eliminates downtime caused by severe grid voltage fluctuations and transient lightning surges in edge locations. It prevents insulation breakdown and equipment failure caused by ambient dust, humidity, and rainwater ingress, while doing away with the single-point-of-failure risk via modular live-swappable architecture.

Who and where it is for

Pole-mount and wall-mount 5G macro sites, edge computing telecom cabins, remote microwave backbone relay links, highway video surveillance nodes, and harsh industrial automation plants.

Core advantages

  • IP55 rated ruggedized enclosure enabling fast pole or wall outdoor mounting
  • Carrier-class efficiency surpassing 96% with ultra-low harmonic distortion
  • Ultra-wide AC operating input range (85V to 300V AC) with 40kA surge suppression
  • Embedded supervisory controller supporting full integration with DCIM and OSS
