Product Overview of ET48450 19-inch Rack Mount Telecom Rectifier

 

The ET48450 DC rack power system is a compact, carrier-grade power conversion platform purpose-built for telecom central offices, mid-to-large data centers, and industrial facilities that demand always-on DC power. It operates from a three-phase 380VAC 63A/4P input and delivers a tightly regulated DC output adjustable from –43VDC to –58VDC, with nominal operation at –53.5VDC. Rated at 18kW maximum output, the system maintains conversion efficiency above 96% across a wide load range, directly contributing to lower energy bills and reduced cooling overhead.

Engineered to endure challenging operating environments, the ET48450 performs reliably over an ambient temperature range of –40°C to +65°C and withstands relative humidity from 5% to 95% (non-condensing). It delivers full output power without derating at altitudes up to 3000 meters. Combining modular scalability, flexible load management, and robust construction, the ET48450 provides a future-ready DC power infrastructure for applications where power continuity is critical and downtime carries significant operational and business consequences.

 

Application Scenarios

  • Telecom shelters with three battery string redundancy

  • Remote base stations with unstable grid (85~300VAC tolerant)

  • Sites requiring humidity monitoring (coastal, rainy, or jungle)

  • Industrial DC power plants with dual surge protection

  • Multi-operator shared sites needing 3 independent battery banks
