It installs 2 (two) Uninterruptible Power Supply (UPS) units and 2 (two) Automatic Transfer Switch (ATS) units as a backup power supply for the Safety Instrumented System (SIS) panel and the Process Control System (PCS) panel. The system uses two main supply sources: PLN grid power as the normal source and a generator set as the backup source. The ATS switches between them automatically when one source fails. The scope of work covers a site survey, installation of the UPS and ATS units, pulling and terminating power and control cables, integration with the existing panels, system function testing, commissioning, the Site Acceptance Test (SAT), and handover. The ATS switches automatically between PLN and the generator set according to operating conditions. The UPS supplies power with no interruption to the SIS and PCS panels during the switchover and during any power supply disturbance. With this backup arrangement of PLN, generator set, ATS, and UPS, power supply to the control and safety systems at the Donggala Depot stays continuous. The configuration minimizes the risk of power loss to critical equipment, prevents communication faults and control system failures, and improves the operational reliability of the facility. The system supports process safety, keeps the instrumentation systems available, and keeps the Donggala Depot operating safely, stably, and without interruption. ## Contact - Company: PT Citia Engineering Indonesia - Email: services@citiaengineering.com - Telephone: +62 21 278 20286 - Office: Jl.
