7.1.1. BSPS Components
The BSPS consists of the following basic components:
! DC Rectifier modules: The Rectifier converts the AC current to DC. The BSPS
can house up to four rectifiers. The rectifiers are “hot plugged” and operate in
parallel. This enables the user to define an “N+1”or “N+2”redundant system.
Each rectifier has its own current sharing system, satisfying a complete sharing
among rectifiers.
! System controller: provides BSPS management control and BSPS operating
information
! Electronic Low Voltage Detector (ELVD): disconnects the battery from the
load, avoiding damage to the battery when over-discharged.
! Battery: provides the BSPS system with back-up power
! Load and battery circuit breakers for DC protection and distribution
! DC Distribution unit: provides circuit breakers for distributing the output
current to multiple BSDUs.
The unit also contains a bypass switch to bypass the LVD.
Note: For power redundancy, at least two rectifiers must be installed.
