Introduction

 

Embedded DC Power provides stable -48V DC power for wireless and fixed access networks, transmission networks and enterprise network equipment. It consists of a power distribution unit, rectifiers, and a controller, etc., and can be deployed independently or embedded into other power cabinets.


Every functional unit is designed to a standard size. The systems, whose height ranges from 2U to 9U with standard 19-inch rack or cabinet installation, have a modular design to facilitate installation and expansion. The system encompasses a wide range of AC input voltage, with accurate battery management and remote management functions.

 

 

GPE48120E System Configuration

 

GPE48120E consists of power distribution unit, rectifier module (from 1 set, up to 5 sets) and 1 monitoring module. The configuration is optional, as following table:

 

Configuration Rectifier Module Monitoring Module Power Distribution Remark
Standard GPR4830A1 GPM48R (With Ethernet Port)

AC power distribution: AC breaker(63A) and wire connection terminal;

DC power distribution: 100A×2 1P

LVLD: 63A×1 1P, 32A×4 1P

LVBD: 20A× 2 1P

For details, please refer to the specifications of modules.

 

GPE48120E Operating Principle

AC power is first input AC-INPUT MCB and then feed into the rectifier module after lightning proof and filtering. AC-INPUT acts as protection to over load and short circuit to AC power. The user’s battery is connected to the DC output side through battery MCB and KM2, and the circuit breaker provides disconnection control, over-load and short-circuit protection to the battery.

Under normal conditions, every parameter of rectifier modules and power distribution unit are all under control of the monitoring module, operating according to the pre-set parameter or user’s commands. If AC mains faults, the battery will power to the system. With the battery discharge, the terminal voltage of the battery starts to descend. When battery voltage is under -47V±0.5V, the monitoring module sends DC under voltage alarm signal and when battery voltage is under -46.0V±0.5V (adjustable), the KM1cuts off non-priority loads and retains power to priority loads. If battery voltage drops to -43.0V±0.5V (adjustable), the KM2 will cut off output of priority loads and then the power system will stop working. If the external AC mains recovers, the system will normally work again. (All above monitoring data are system default values and can be reset by user).


Except for battery over-discharge protection, battery or load over-temperature protection is prohibitive under default, users can send command to activate or inactivate according to the demanding.
