30kw 9U Rack Mounted Intelleigent Telecom Rectifier Power Distribution System with LLVD BLVD

30kw 9U Rack Mounted Intelleigent Telecom Rectifier Power Distribution System with LLVD BLVD

Product Overview

The 30 kW DC48V rectifier system is a high-capacity power solution engineered to guarantee uninterrupted DC power for telecommunications, data centers, and critical industrial processes. Operating from a 380VAC three-phase input, it produces a precisely regulated DC output adjustable from –43 VDC to –58 VDC, with a nominal setpoint of –53.5 VDC. With industry-leading conversion efficiency exceeding 96% even at full load, it is exceptionally well-suited for energy-optimized, high-density deployments.

Modular Architecture for Maximum Uptime
Designed for scalability and redundancy, the system accommodates up to ten hot-swappable 3000W rectifier modules in a compact 9U, 19-inch rack-mountable chassis (IP20 rated). This configuration supports N+1 redundancy to ensure continuous operation during maintenance or module failure. Each lightweight module (<2 kg) features forced-air cooling for reliable thermal performance. Advanced power factor correction (≥0.99) and low total harmonic distortion (THDi ≤5%) ensure high-quality power delivery and reduce stress on upstream electrical infrastructure. Front-access design and top-panel cable entry simplify installation and servicing.

Comprehensive Intelligence and Load Control
The integrated distribution panel includes both LLVD (Limited Load Voltage Disconnect) and BLVD (Battery Low Voltage Disconnect) functions for intelligent, flexible load management. The system is managed by a sophisticated onboard controller offering extensive monitoring and configuration options. It features 3 inputs for ambient temperature sensors, 7 digital inputs for external status monitoring, and 6 programmable dry-contact relay outputs for comprehensive alarm management. Remote oversight is supported via RS485 and SNMP interfaces, while an intuitive front-panel LCD screen enables convenient local configuration and real-time status checks.

Engineered for Extreme Reliability
Built to perform in the world's harshest environments, this rectifier system operates at full specification without derating from -40°C to +65°C and in relative humidity from 5% to 95% (non-condensing). It maintains full output power at altitudes up to 3000 meters. By combining high-density power, intelligent control, and robust construction, the ET series provides a future-proof DC power foundation for any mission-critical facility where downtime is not an option.
