What this product is

What this product is

Architecturally, the R48-4000e utilizes full DSP-controlled conversion. The front-end power factor correction stage ensures near-unity power factor (>0.99) and low total harmonic distortion (THD <5%), feeding a resonant LLC full-bridge DC-DC converter for minimal switching losses. It connects to the subrack via an integrated blind-mate interface handling DC power, AC input, alarms, and dual CAN bus communications, compliant with international telecom EMC and safety standards.

What problem it solves

It eliminates equipment vulnerability caused by AC utility sags and surges through a wide operating voltage window; cuts operational expenditure (OPEX) and cooling overhead via high-efficiency conversion (≥96.0%); maximizes subrack power density to reclaim costly rack units in space-constrained sites; and prevents system-level service outages via live hot-swappable active load sharing.

Who and where it is for

Ideal for 5G macro core central offices, mobile switching centers (MSCs), high-density data center telecom rows, fiber optical transmission terminals, and Vertiv NetSure 701/801 series power cabinets demanding N+1 or N+M carrier-grade redundancy.

Core advantages

  • Bridgeless PFC and LLC resonant topology yield up to 96.0% peak efficiency, reducing data center PUE.
  • Delivers 4000W (-48V/83.3A) high-density output, minimizing rack footprint and slot occupation.
  • Supports live hot-swappable operation and CAN bus intelligent current sharing for zero downtime.
  • Wide input voltage range and robust EMC protection withstand harsh grid surges and fluctuations.
