3U 19-Inch Embedded Power System
,48V 400A Embedded DC Power System
,24kW Rack Mount Power System
The ETP48400‑C3B1 is a next‑generation 3U 19‑inch rack high‑density embedded DC power system designed specifically for 5G base stations, macro sites, stock station expansion and reconstruction, and new 3G/4G/5G wireless sites. It converts a wide‑range AC input into a stable, adjustable -48V / -57V DC output, with a maximum capacity of 400A / 24kW and ultra‑high power density in a compact 3U chassis.
Adopting an innovative modular architecture, full digital intelligent control and front maintenance design, this system supports modular distribution expansion, multi‑level power‑down management and intelligent peak shaving. It is the preferred high‑efficiency, high‑reliability power solution for 5G network construction and station capacity upgrades.
- Ultra‑high power density: 3U height with max capacity 24kW / 400A, significantly saving cabinet space
- Innovative architecture design supporting modular distribution expansion for flexible capacity upgrades
- Wide AC input range of 85–300VAC, compatible with unstable grids and generator power supply
- Supports -57VDC constant voltage output to meet 5G high‑power AAU long‑distance power supply needs
- Equipped with intelligent power distribution unit supporting multi‑level power‑down management for diversified 5G services
- Intelligent peak shaving and valley filling: grid adaptive adjustment reduces station operation costs
- Supports Huawei BoostLi lithium battery for intelligent battery management and extended battery life
- Hot‑swappable rectifier modules (R4875G) for plug‑and‑play replacement without system shutdown
- Full front maintenance and front wiring for easy installation and later maintenance
- Intelligent SMU02C monitoring: real‑time data display, fault alarms and remote online maintenance
- Wide operating temperature range of -40°C to +70°C, suitable for high‑altitude and harsh environments
- Complete protection: OVP, OCP, SCP, OTP, LVBD and surge protection
- High power factor ≥0.99 and low THD for green, grid‑friendly operation
- Compliant with CE, RoHS, UL and global telecom safety standards
