What this product is

What this product is

Architecturally, the S48-3000 integrates an active power factor correction (APFC) circuit, a flexible high-voltage DC-DC stage compatible with MPPT solar controllers, and an isolated resonant LLC DC-DC converter. It is built with an independent front-to-back airflow channel, conformal-coated industrial-grade printed circuit boards, and complete CAN bus telemetry, fully compliant with global telecom safety standards such as IEC/EN 60950 and Telcordia GR-1089-CORE.

What problem it solves

It eliminates the high fuel dependencies, elevated maintenance overhead, and carbon footprints of diesel-generator-dependent telecom towers in weak or off-grid areas. Moreover, its wide input voltage envelope prevents field rectifier burnouts from severe mains surges, while full hot-plug support removes the risk of DC system downtime during scheduled field maintenance.

Who and where it is for

Ideal for cellular 4G/5G macro sites, hybrid solar-diesel-battery telecom installations, off-grid microwave relay stations, and mission-critical telecom outdoor power cabinets requiring flexible solar and AC grid rectified -48V DC power.

Core advantages

  • Integrated MPPT and AC dual-input architecture enables smart multi-energy scheduling, drastically reducing diesel generator dependency for remote sites.
  • Advanced APFC circuit and wide input voltage range (85V-300V AC) withstand severe grid fluctuations and surges, preventing overvoltage breakdown.
  • Delivers 3000W rated power with peak conversion efficiency exceeding 96.0%, effectively minimizing telecom site energy consumption and carbon footprint.
  • Supports hot-swappable technology and sealed dustproof air ducts, complying with IEC/EN safety and EMC Class B standards for maintenance-free reliability.
