The Accunergi Modular Rectifier Battery Charger is a high-frequency switching modular power system designed to deliver reliable and expandable DC power across output voltages ranging from 24V to 220V DC. Built using transformer-less technology proven in the telecommunications industry, the system provides a compact, lightweight, and space-efficient solution for applications requiring scalable and continuous DC power availability.
Its modular architecture allows the system to expand as load demand increases while maintaining the same physical footprint. With hot-swappable power modules and configurable redundancy options, it ensures uninterrupted operation and simplified maintenance without system shutdown.
Modular Scalability: Expandable for higher load demand and larger battery capacities
Hot-Swappable Modules: Faulty modules can be replaced online without power interruption
Redundancy Options: Supports 1+1, n+1, or n+2 redundancy configurations
Compact Footprint: Lightweight design with unchanged footprint even when capacity increases
