DC48V 7U 36kw Industrial Rectifier System Support Remote Management RS485
Product Overview of 48VDC 7U 36kw Industrial Rectifier System
The ET-Series 7U 36kW Integrated DC Rack Power System is a high-density, carrier-class power platform engineered to deliver uninterrupted DC power for telecommunications central offices, mid-to-large data centers, and industrial facilities. Operating from a three-phase 380V AC input (with no internal circuit breaker), it supplies a precisely regulated DC output adjustable between –43V and –58V, typically set at –53.5V. With a maximum output of 36kW, the unit achieves conversion efficiencies exceeding 96% across most of its operating range, significantly reducing energy consumption and the associated costs of cooling.
Designed with a focus on maximum uptime and simplified maintenance, this system features a true modular architecture supporting up to twelve 3000W rectifier modules, allowing for N+1 or greater redundancy. Each hot-swappable module, weighing under 2kg, utilizes forced-air cooling and integrates active power factor correction (≥0.99) alongside low total harmonic distortion (THDi ≤5%) to ensure grid compliance and a stable DC output. The entire assembly fits within a 7U (19-inch) rack-mountable chassis. Its IP20-rated enclosure ensures protection against accidental contact, while front-access hot-swap capabilities streamline service. Rear copper busbars provide a robust, low-impedance path for high-current connections.
Key Highlights of 48VDC 7U 36kw Industrial Rectifier System
High capacity – 36kW: Supports larger telecom shelters, edge data centers, and industrial DC plants
N+1 redundancy with 12 modules: System operates at full 36kW even during module failure or maintenance
Four independent LLVD stages: Gradually shed non-critical loads in sequence – maximizes runtime for essential equipment
Each LLVD stage includes 63A + 125A: Handles both medium and high-current loads per stage
BLVD protects battery string: Keeps ultra-critical loads (6A~63A) powered until final disconnect
Battery breakers reserved: Flexible integration with customer-specified overcurrent protection
