25.2V 15A Li-ion Charger for 6S 22.2V Battery
Phonix® FX21015000 is an infrastructure-grade 25.2V 15A (378W) fast charger matching 6S Li-ion/Li-Po industrial packs. Built in a fully sealed, fanless 233X108X64mm enclosure, it eliminates conductive dust failures while maintaining ≥88.5% efficiency under pure natural convection (≥94.0% under forced air). Backed by an active Interleaved PFC matrix, certified 50,000-hour MTBF, and our 5-year factory warranty, this MCU-governed module delivers unyielding fleet readiness in harsh workshop environments.
Description
Sustained Harmonic Distortion Suppression via Interleaved Active PFC Topology
Injecting a continuous 378W high-current fast-charge curve into heavy battery configurations or centralized charging racks mandates highly sophisticated control over input line structures to protect facility distribution networks from severe phase disruptions and voltage imbalances. The Phonix® FX21015000 integrates an interleaved active power factor correction circuit working alongside optimized LLC resonant converter topologies to preserve exceptional utility grid parity. Housed in a flame-retardant solid polymer chassis measuring 233X108X64 mm and weighing 1900g, the unit rejects mechanical cooling fans in favor of static natural air convection. Eliminating open-air airflow channels bars entry to conductive carbon scale, fine processing soot, and humid tracking paths that trigger early component value drift or internal layer shorts. This closed-chassis architecture limits maximum case temperature rise to under < 40°C during maximum constant-current bulk charge phases, shielding internal multi-layer PCB paths and reinforcing fleet operational uptime.
