Product Overview of 48VDC 750A Base Station Rectifier Power Supply

The ET48750-M7E106 DC rack power system is a high-capacity, carrier-grade power conversion platform engineered for core telecom nodes, large-scale data centers, and mission-critical industrial facilities where power continuity is essential. It interfaces via terminal blocks—configured as L1×3, L2×2, L3×2, and N×6—to support AC inputs. The system delivers a precisely regulated DC output adjustable from –43VDC to –58VDC, with a nominal setpoint of –53.5VDC. Rated at a full 30kW output capacity, it sustains conversion efficiency above 96% even under heavy load, significantly reducing energy loss and operational expenditure.

Rectifier Module of 48VDC 750A Base Station Rectifier Power Supply

The architecture is fully modular and fault-tolerant, supporting up to ten 3000W hot-swappable rectifier modules in an N+1 or higher redundancy scheme. Each rectifier module weighs under 2kg and leverages forced-air cooling alongside advanced power factor correction (≥0.99) and very low total harmonic distortion (THDi ≤5%), ensuring grid-friendly operation and consistent power quality. The entire system is housed in a 6U-high chassis built to fit standard 19-inch racks. Front-access hot-swap maintenance and top-panel cable routing simplify installation and field service, while the IP20-rated enclosure protects against accidental contact and ingress of solid foreign objects.
