What this product is
What this product is
The ZTE PSU-AC is a compact, hot-swappable switch-mode rectifier engineered for wireless base station power subracks and outdoor enclosures. It converts single-phase AC grid or generator power into stabilized -48V DC power to energize BBUs, RRUs, and network transmission gear while managing battery float and boost charging.
What problem it solves
Mitigates power outages caused by weak rural or unstable urban grids via an ultra-wide AC operating window, suppresses grid harmonic pollution, and reduces station OPEX through high conversion efficiency (≥96%).
Who and where it is for
Macro base station BBU power frames, outdoor telecom cabinets, FTTx central offices, remote RRU power feeding, and microwave repeater sites.
Core advantages
- Ultra-wide 85VAC to 300VAC input range for resilient operation in unstable grids
- High conversion efficiency ≥96% to optimize site PUE and thermal dissipation
- Full DSP digital control ensuring active parallel current sharing imbalance ≤±3%
