The Delta DPR 48/50-G is a carrier-grade, single-phase hot-swappable switch-mode rectifier module engineered for modern telecommunication and data networks. It converts 90V to 300V AC wide input power into stable 53.5V DC output with a rated power of 2900W (50A continuous), delivering an industry-leading peak energy efficiency of 96.2% along with active digital power factor correction.

The DPR 48/50-G is packaged in a high-density 1U plug-in metal cassette, incorporating multi-stage EMI suppression, digital active PFC, LLC resonant converter topology, and low-loss synchronous rectification integrated with robust rear blind-mate hot-plug connectors.
Eliminates low-line AC grid dropouts, decreases OPEX via lower thermal dissipation, mitigates power cabinet space constraints, and solves module current-sharing imbalance in parallel telecom power plants.
Ideal for 4G/5G macro cell outdoor cabinets, telecom central offices, optical transport nodes (OLT/DWDM), industrial IoT substations, and critical mission enterprise DC backbones.
