Product Description
🏭 MACRO BASE STATION | 1U EMBEDDED MODULE | 3kW | NATURAL COOLING
DSA3000-S54E · 3kW 1U Embedded Rectifier
For 48V Telecom Systems
Ultra-compact, high-density rectifier module specifically designed for macro base stations and telecom central offices. Delivers 3kW of regulated DC power in a slim 1U form factor (287×105×40.8mm). Features wide universal input (80-300Vac), 42-58Vdc adjustable output (62.5A max), 96% efficiency, natural convection cooling, and CAN 2.0 communication. Ideal for embedded power shelves and distributed 48V architectures.
📡 Optimized for Macro Base Stations
📏 1U Ultra-Slim Design Height only 40.8mm – fits standard 19″ telecom shelves and embedded cabinets. High power density (3kW per module) maximizes rack utilization.
🌍 Universal Wide Input 80~300Vac – works with single-phase or three-phase mains worldwide, tolerating wide voltage fluctuations and unstable grids.
🔋 Wide Output Range 42V to 58Vdc adjustable (62.5A max) – perfect for 48V lithium or lead-acid battery charging and direct load powering.
📈 High Efficiency (96%) 96% efficiency at full load reduces heat generation and energy costs. Lower thermal stress improves long-term reliability.
💨 Natural Convection Cooling Fanless operation eliminates acoustic noise and moving parts – ideal for noise-sensitive indoor environments and low-maintenance deployments.
📡 CAN 2.0 Communication Standard CAN 2.0 interface enables remote monitoring, parallel current sharing, N+1 redundancy, and seamless integration with site controllers.
🌡️ Extreme Temperature Range -40°C to +75°C operation (derating above 55°C) – reliable for outdoor shelters, remote huts, and harsh climate regions.
🛡️ Comprehensive Protections Input over/under voltage, output overvoltage (≥59V), overcurrent, short circuit, and over temperature protection – auto-recovery ensures maximum uptime.
