What this product is

What this product is

Electrically, the Vertiv R48-1800A incorporates a two-stage conversion architecture: an active front-end EMI and PFC stage to optimize power factor and minimize harmonic distortion (THD), followed by an isolated high-frequency DC-DC resonant converter stage. Complete with embedded DSP microprocessor monitoring, integrated blind-mate power connectors, and safety compliance with IEC/EN 60950 and EN 300 386 EMC, it provides stabilized telecom-grade DC energy.

What problem it solves

This rectifier eliminates power outages caused by unstable and swinging electrical grids in remote installations, dynamically handling severe low-voltage sags down to 85V AC without system dropouts. It protects downstream critical loads against damaging surges, avoids high-temperature thermal shutdowns common in sealed outdoor cabinets, and slashes operational downtime through live hot-swap maintenance without interrupting the live DC bus.

Who and where it is for

Ideal for 3G/4G/5G macro and micro base transceiver stations (BTS), outdoor telecom power cabinets, broadband optical line terminal (OLT) installations, private enterprise networks, critical industrial control systems, and modular NetSure DC power subracks.

Core advantages

  • Wide Input Voltage Range: Integrated Boost APFC circuit handles 85V-300V grid fluctuations, ensuring continuous base station operation.
  • Industrial Thermal Design: -40°C to +70°C wide temperature operation with intelligent speed fans eliminates unexpected thermal shutdowns.
  • Seamless Hot-Pluggable Architecture: Live hot-swappable design allows fault module replacement without interrupting DC bus power.
  • Digital Intelligent Control: Microprocessor-based control with real-time NetSure monitoring integration, compliant with EN 300 386 standards.
