What this product is

What this product is

The DPC DUMC-4850H is a standardized 19-inch rack-mounted DC power architecture integrating high-efficiency switch-mode rectifiers, a digital Central Supervisory Unit (CSU), and an integrated AC/DC distribution block. It converts raw utility or generator AC power into clean, regulated -48V DC to power sensitive telecom active loads while maintaining float charging on back-up batteries with zero-millisecond transition during grid dropouts.

What problem it solves

Mitigates severe physical footprint constraints inside outdoor telecom enclosures, protects critical communications electronics against severe grid fluctuations (85VAC to 300VAC), and prevents catastrophic battery degradation through precision multi-stage charging and dual LVD controls.

Who and where it is for

4G/5G small cell base stations, RRU distributed power feeds, broadband enterprise access nodes, rail signaling shelters, roadside ITS cabinets, and ruggedized edge computing hubs.

Core advantages

  • Ultra-wide AC input from 85VAC to 300VAC handles unstable grids, eliminating downtime in remote base stations.
  • High-density 19-inch 1U embedded architecture with a 50A rectifier perfectly fits space-constrained edge cabinets.
  • Advanced DK04 microcontroller provides intelligent battery management and temperature compensation to maximize lifespan.
  • Peak conversion efficiency exceeding 95.5% significantly lowers operating energy costs and thermal dissipation.
