Request a quoteThe APR48-ES incorporates a fully digital power conversion architecture driven by an onboard micro-controller/DSP. The front stage employs an active power factor correction (PFC) boost topology accepting a wide input voltage window (90V–300V AC) while maintaining near-unity power factor and negligible THD. The DC-DC transformation utilizes an LLC resonant topology providing low-loss soft switching, galvanic isolation, and tight regulation over the 48V DC bus. Module-to-controller communication is executed via high-speed internal CAN bus for dynamic auto-sharing of load current.
Eliminates the unsustainable operational electricity and thermal HVAC costs common to legacy 88%–92% legacy rectifiers; prevents network drops and component destruction during extreme utility grid fluctuations or brownouts; removes single points of failure through hot-swappable N+1 modular redundancy.
