What this product is
What this product is
A modular, single-phase hot-pluggable AC/DC power conversion unit designed for 19-inch subracks, featuring integrated Active Power Factor Correction (PFC), high-frequency isolation transformer stages, an intelligent microcontroller, a blind-mate high-current rear backplane connector, and intelligent front-to-back forced-air cooling.
What problem it solves
Eliminates network downtime caused by unstable rural grid voltages, mitigates thermal degradation in harsh outdoor shelter environments, lowers maintenance OPEX via hot-swap architecture, and prevents cross-module circulating current in multi-rectifier parallel arrays.
Who and where it is for
Cellular telecom macro base stations, distributed BBU/RRU power enclosures, fiber central offices (FTTx/OLT), railway signaling and SCADA power, power utility substation DC panels, and edge telecom data cabinets.
Core advantages
- Ultra-wide 90V to 300V AC input window ensures continuous operation during severe grid brownouts
- True hardware-based autonomous active current sharing bus keeps parallel unbalance below 3%
- Microprocessor-controlled variable speed cooling fan optimizes acoustic profile and component lifespan
- Hot-plug field swappable architecture reduces Mean Time to Repair (MTTR) down to minutes
