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-dense 1U rack-mount chassis optimizes valuable vertical payload capacity in cramped telecom cabinets.
- High conversion efficiency of ≥96.0%, reducing operational thermal dissipation and overall site HVAC cooling overhead.
- Integrated dual-level Low Voltage Disconnect (LLVD non-critical load drop and BLVD battery protection) to avert permanent battery pack sulfation or over-discharge.
