FAILURE OF ANY UNIT LEADS TO THE FAILURE OF
POWER TO CRITICAL LOADS:
•A performance rated UPS needs a performance rated BPS
•Close scrutiny and engineering evaluation is required on each module
•Power loss to critical loads is formidable
•MTBF is determined by the combined reliability of the system modules
