19-Inch 2U Embedded DC Power System
,Dual AC HVDC Input Telecom DC Power Supply
,10kW High Power Capacity Rack Mount DC Power System
The ETP48200‑B2A1 is a high‑efficiency, 19‑inch standard 2U embedded DC power system designed for telecom access networks, transmission equipment, enterprise communications, 4G/5G base stations and OLT equipment rooms. It converts wide‑range AC or HVDC input into a stable, adjustable −48V DC output, with a maximum system capacity of 10kW.
Adopting a modular, hot‑swappable design with front wiring and maintenance and intelligent monitoring, this system delivers high efficiency, flexible configuration and reliable operation. It supports both AC (85–300VAC) and HVDC (100–420VDC) input, making it a universal embedded power solution for global telecom infrastructure.
- Standard 19‑inch 2U rack/embedded design with a compact structure that saves installation space
- Dual input support: wide AC 85–300VAC (45–66Hz) plus HVDC 100–420VDC for strong grid adaptability
- Supports R4815 (1000W) and R4830 (2000W) high‑efficiency rectifier modules, with a maximum system power of 10kW
- Rectifier efficiency up to 96%, with a module sleep function for further energy savings
- Hot‑swappable modules: plug‑and‑play replacement without system shutdown
- Full front maintenance and front wiring for easy installation and operation
- Intelligent monitoring (SMU11B/SMU11C): supports FE, RS485, SNMP, remote monitoring and fault alarms
- Intelligent battery management and protection that effectively extends battery service life
- Wide operating temperature range of −40°C to +65°C, suitable for high‑temperature and high‑altitude environments
- Complete protection: OVP, OCP, SCP, OTP, LVBD and surge protection
- Protection class IP20 with natural cooling for stable, reliable operation
- Compatible with three‑phase, single‑phase and dual‑live wire input
