FUNCTION & CONTROL METHOD
Online double-conversion UPS and DC battery systems are sized from connected load, autonomy, redundancy, inrush and maintenance philosophy.
ELECTRICAL, INSTRUMENTATION & AUTOMATION
UPS & DC Systems
Maintains clean, uninterrupted power for control, safety, communication and critical instrumentation.
MAIN HARDWARE & SYSTEM BOUNDARY
UPS rectifier/inverter, static bypass, batteries, chargers, DC distribution, monitoring, isolation transformers and maintenance bypass.
CRITICAL DESIGN INPUTS
Approved P&IDs and control philosophy, process ranges and alarm/trip limits, hazardous-area classification, environmental conditions, I/O and load lists, availability/redundancy target, package interfaces, communication protocols, cybersecurity and client standards.
ENGINEERING DELIVERABLES
System architecture, instrument/equipment index, datasheets, I/O list, hook-ups, loop and wiring diagrams, cabinet/panel drawings, cable schedule, network drawings, control narratives, cause-and-effect, logic diagrams, graphics, test procedures and as-built backups.
FUNCTIONAL SAFETY, RELIABILITY & CYBERSECURITY
N+1 or parallel redundancy, battery-room ventilation, fire detection, earth fault, bypass transfer, autonomy alarms and periodic testing are defined.
TESTING, COMMISSIONING & APPLICATIONS
DCS, PLC, SIS/ESD, F&G, analyzers, telecom and critical switchgear controls. Load-bank and autonomy testing form part of SAT.
