What this product is

What this product is

This rectifier functions as the central AC-to-DC conversion engine within telecom power plant infrastructure and enterprise DC power distribution units (PDU). Its internal architecture features a two-stage conversion scheme: an active Power Factor Correction (PFC) front-end that continuously shapes the input current waveform to achieve a power factor greater than 0.99 while mitigating grid harmonic reflections; followed by an isolated LLC resonant DC-DC converter utilizing Zero-Voltage Switching (ZVS) and synchronous rectification. Fully managed by internal high-speed microcontrollers, the module continuously monitors vital operational parameters and communicates real-time diagnostic and control telemetry over a high-speed multi-drop CAN/RS485 industrial bus.

What problem it solves

It resolves frequent rectifier catastrophic burnout caused by poor grid quality, extreme voltage sags, and surges in marginal or rural deployments; substantially curtails ongoing operational expenditure (OPEX) and data center thermal loads through its 96.5% peak energy efficiency; and completely eliminates critical system downtime through hot-swappable, active current-sharing N+1 redundancy that eliminates any Single Point of Failure (SPOF).

Who and where it is for

5G macro base station outdoor shelters, enterprise data center edge micro-modules, central telecom switching offices, railway signaling systems, and critical industrial automation distributed control systems.

Core advantages

  • 96.5% peak conversion efficiency significantly reduces parasitic thermal load and OPEX.
  • Dual-DSP digital control architecture ensures high-precision active current sharing and dynamic stability.
  • Ultra-wide 85V–300V AC input tolerance guarantees resilience against severely fluctuating grids.
  • True hot-plug modularity with comprehensive internal fail-safe protection ensures zero-downtime maintenance.
