Product Overview
The ET48300-M5S65 DC rack power system provides a high-capacity, resilient DC power solution designed specifically for telecommunications infrastructure, data center operations, and industrial applications requiring dependable DC power distribution. It accepts 220VAC 125A/2P (dual live-line supported) input and delivers a stable DC output adjustable between –43VDC to –58VDC, with a nominal operating point of –53.5VDC. Offering a maximum output capacity of 18kW, this system reliably supports high-demand installations while achieving power conversion efficiency exceeding 96%.
Featuring a modular and redundant design, the system supports up to 6*3000W rectifier modules configured for N+1 redundancy, with each compact module weighing under 2kg. The rectifiers utilize forced-air cooling, achieve a near-unity power factor (≥0.99), and maintain low total harmonic distortion (THDi ≤5%) for efficient and clean power conversion. With front-access maintenance, top-panel cabling, and IP20 ingress protection, the 3U rack-mountable chassis emphasizes operational safety, ease of service, and straightforward integration into standard 19-inch cabinets.
The DC distribution panel is equipped with 2*125A/1P battery circuit breakers and includes LLVD & BLVD functionality for secure and flexible power management. System intelligence is provided by a dedicated controller featuring 3 analog sensor inputs, 7 digital status inputs, and 6 configurable dry-contact alarm relays. Remote monitoring and management are enabled via RS232/485 and SNMP interfaces, while an integrated LCD display allows for local status viewing and configuration.
Engineered to perform in demanding conditions, the system operates across an extended temperature range from –40℃ to +65℃, tolerates relative humidity from 5% to 95% (non-condensing), and maintains full performance at altitudes up to 3000 meters. Combining a scalable modular architecture with proven reliability, this 18kW DC power system stands as a robust and scalable energy solution for critical infrastructure where power availability is paramount.
