The DPFOX series power distribution cabinets are end-point intelligent power distribution solutions specifically designed for IDC data centers and various precision industrial server rooms. Featuring a dedicated dual-door design for IDC environments with a blue industrial aesthetic, these cabinets boast a robust structure and excellent shock resistance, making them the core terminal equipment for data center energy management—widely recognized as the intelligent power management solution at the facility's periphery. This product transcends the limitations of traditional power distribution systems by integrating multi-layer switching components, high-precision power monitoring instruments, and smart data acquisition modules, enabling comprehensive control spanning power connection, distribution, monitoring, and protection across the entire power usage lifecycle in server rooms.
In terms of voltage compatibility, the product covers all mainstream voltage levels and is compatible with three major power supply standards: AC 380V, DC 48V, and high-voltage DC 240V/336V. It flexibly meets the electrical requirements of various loads such as servers, network equipment, precision manufacturing instruments, and communication devices, demonstrating exceptional versatility. The hardware features a fixed design with scientifically optimized internal space that accommodates additional power distribution circuits, maximizing cabinet space utilization and perfectly adapting to modern high-density, compact data center layouts. Standard dimensions are 2200 mm (height) × 600/800/1000/1200 mm (width) × 600/1200 mm (depth), with full-size customization available per client specifications. Available in gray-white or black finishes, or custom color combinations can be specified. The unit supports vertical floor-standing installation with optional casters for easy relocation and layout adjustment. Cable routing options include upper/inlet, lower/inlet, upper/outlet, and lower/outlet configurations, accommodating diverse data center wiring schemes.
The electrical configuration and protection system is comprehensive: AC head cabinets have an input rated current range of 100 A to 630 A, equipped with molded case switches for protection; DC head cabinets (DC 48 V) operate within an input current range of 160 A to 1600 A and feature fuse protection; high-voltage DC head cabinets (DC 240 V/336 V) also support an input current range of 160 A to 1600 A, offering options for molded case circuit breakers or fuses. Output terminals can be flexibly configured with protective components such as miniature circuit breakers or fuses depending on the downstream load requirements. The equipment incorporates a Class C lightning protection module, effectively safeguarding sensitive downstream devices against lightning surges and operational overvoltages. It includes a built-in high-precision acquisition unit and human-machine interface that collects and displays real-time data on all electrical parameters—including voltage, current, power, energy levels, and switch status—with visual presentation, enabling operators to monitor distribution system conditions intuitively. The system also supports remote data transmission and integration with centralized monitoring platforms in server rooms.
The product is equipped with professional power distribution management system software and employs a distributed intelligent control strategy, effectively mitigating single-point failure risks and enhancing the operational reliability of the entire end-user power distribution system. Delivery options include standardized mass production and customized services: standardized products can be rapidly supplied to meet general data center requirements, while customized solutions allow adjustments to circuit configurations, protection parameters, and cabinet structures for specific loads or environments. The product has obtained CQC voluntary certification, passed seismic testing, and undergone comprehensive performance evaluations, ensuring its quality and safety are backed by authoritative certifications.
