Product Overview of 12U 16kw Hybrid Power Rectifier System
Designed for telecommunications infrastructure, medium-to-large data centers, and demanding environmental conditions, the 12U Hybrid Power Rectifier System delivers stable AC and DC power distribution. It accepts dual inputs—220V AC and photovoltaic (PV)—and produces a precisely regulated DC output adjustable from –43V to –58V (typically –53.5V). In addition, the system provides a 110V AC output at 16A, complete with Class C surge protection. With a maximum capacity of 30kW and conversion efficiencies exceeding 96% across most of its load range, the unit substantially reduces energy consumption and associated cooling demands.
Built for continuous operation, the rectifier accommodates up to 10 hot-swappable modules (6*3kw powered by PV and 4*4kw by AC), supporting N+1 or higher redundancy configurations. Each module features forced-air cooling, active Power Factor Correction (PFC ≥ 0.99), and low Total Harmonic Distortion (THDi ≤ 5%), ensuring clean grid interaction and stable output. All components are installed in a 12U, 19-inch rack-mountable chassis rated IP20. Front-access hot-swap capability simplifies maintenance, while rear-mounted copper busbars provide a low-impedance, high-current connection path.
The integrated DC distribution includes battery low-voltage disconnect (BLVD), enabling prioritized load shedding to preserve critical battery reserves during outages. An advanced system controller offers comprehensive monitoring and programmable logic via analog inputs (AI), digital inputs (DI), and digital outputs (DO). Remote management is supported through RS485 and SNMP interfaces, giving operators full visibility into alarms, performance metrics, and rectifier status. A front-panel LCD also allows convenient on-site configuration and diagnostics.
