2U Modular Telecom DC Power System Integration with MC2600 Power Management
Product Overview of 2U Modular Telecom DC Power System Integration
The ET4890-M3F32 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 single-phase 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 9kW, 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 3*1.74kw 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 2U rack-mountable chassis emphasizes operational safety, ease of service, and straightforward integration into standard 19-inch cabinets.
The DC distribution panel is equipped with 1*63A 1P battery circuit breakers and includes Battery Low Voltage Disconnect (BLVD) functionality for secure and flexible power management. System intelligence is provided by a dedicated controller featuring 2 analog sensor inputs, 8 digital status inputs, and 2 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.
