| High Light | 5U telecom DC power system ，16kW 48V telecom power ，300A single phase power system | ||
The ET48300-M7F45 is a medium-capacity -48V DC telecom power system designed for sites that require more output capacity than compact 2U systems but do not need the full scale of a 24kW three-phase platform. With a 5U subrack structure, single-phase 220VAC input, and maximum system capacity of 16kW, it provides a practical balance between rack space, output capability and maintenance convenience.
This system supports up to four 4kW rectifier modules, delivering a maximum current class of 300A. It is suitable for telecom cabinets and indoor equipment rooms where stable DC supply, battery backup and multiple protected load outputs are required. The front layout clearly separates AC input, surge protection, LLVD branches, BLVD branches, battery breakers, controller area and communication terminals, making wiring, inspection and breaker operation easier during installation or field service.
Single-phase 220VAC input design for sites without three-phase power access.
4–16kW scalable capacity, using four 4kW rectifier modules.
300A DC distribution capability for medium-load telecom applications.
Top inlet and top outlet cabling for organized cabinet wiring.
Front maintenance structure supports quick inspection and module replacement.
LLVD and BLVD load separation helps protect battery energy for priority equipment.
Integrated AC SPD and DC SPD improve surge protection at power entry and DC distribution sides.
LCD controller with RS485 and SNMP supports remote monitoring and alarm management.
Hot-pluggable rectifier and controller design reduces downtime during maintenance.
The ET48300-M7F45 is suitable for wireless base stations, access network cabinets, fiber and microwave transmission sites, enterprise communication rooms, telecom shelters, railway and highway communication facilities, and medium-sized -48V DC backup power systems.
