What this product is

What this product is

Architecturally, the R4830N2 integrates an active power factor correction (APFC) input pre-regulator followed by an isolated high-frequency resonant DC-DC converter stage, orchestrated by a high-speed DSP microcontroller. It supports integrated CAN bus telemetry for seamless integration with Huawei SMU series controllers and conforms strictly to IEC/EN 60950-1, UL 60950-1, and stringent telecom EMC standards.

What problem it solves

It resolves telecom field vulnerabilities caused by severe grid voltage fluctuations, brownouts, and surges, eliminates excessive cabinet thermal dissipation through high conversion efficiency, and mitigates downtime risks via true live hot-plug capability that prevents contact arcing and avoids service disruption during maintenance.

Who and where it is for

Engineered for wireless base stations (BTS, NodeB, eNodeB, gNodeB), outdoor integrated power enclosures, optical transmission nodes, central switching centers, and enterprise mission-critical telecom networks requiring continuous DC availability.
