When a surgical team loses power in the middle of a procedure, there is no room for mistake. Because of this one fact, every operating room in the UAE has a backup power chain that was designed just for it. This is also why Socomec UPS for operating room UAE projects has become one of the most-searched specifications among MEP consultants and hospital engineers. This guide talks about what the standard needs, how Socomec’s UPS and isolated power technology can meet those needs, and how to pick the best partner for application in Dubai and the rest of the Emirates.
Why Operating Theatres in the UAE Can’t Rely on Standard Backup Power
On paper, Dubai’s power grid is one of the most stable in the world. In 2025, DEWA reported that Customer Minutes Lost was only 0.82 minutes per customer. This was less than the 0.94 minutes per customer reported in 2024 and much less than the 15-minute average recorded by the top European utilities. Still, that big number only talks about continuity at the grid level, not what happens in an operating room during a millisecond voltage drop, a switching transient, or a planned maintenance outage.
Any break, no matter how short, is too much for a ventilator, anesthesia monitor, or surgery laser. Theater power is designed as a separate, standards-based system so that it doesn’t depend on the stability of the grid.
A lot of people want that engineering fast. The number of approved healthcare facilities in Dubai rose from about 5,340 in 2024 to about 5,800 in 2025, a gain of more than 8%. There are now 55 hospitals and 60 day surgery centers in the city. MOHAP’s 2023 statistical yearly report said that there were 173 hospitals in the UAE, including 117 private hospitals that saw more than 19 million patients that year. The operating rooms in all of those buildings depend on an electrical design that meets safety standards.
IEC 60364-7-710 Explained: The Rulebook for Group 2 Medical Locations
The international standard for electrical installations in medical buildings, IEC 60364-7-710, says that operating rooms are in Group 2 of medical sites. There are strict rules about how quickly power must be restored after a fault and what kind of grounding scheme the circuit must use.
Group 0, 1 and 2 Locations
- Group 0 — rooms where no equipment is applied directly to the patient.
- Group 1 — locations where applied parts are used externally, or invasively, but a brief supply loss is not immediately life-threatening.
- Group 2 — locations such as operating theatres, intracardiac procedure rooms, and other vital-treatment areas where any discontinuity of supply can endanger a patient’s life.
Class 0 vs Class 0.5 Transfer Times
Within Group 2, the standard defines how quickly a backup source must take over:
- Class 0.5 — transfer completed within 0.5 seconds, typically via an automatic or local transfer switch.
- Class 0 — a true no-break transfer, with zero interruption, generally delivered through a UPS or static transfer switch feeding the medical IT circuit.
Which class applies depends on the criticality of the connected equipment and the local adoption of the standard, which is why UAE facility design teams size this decision early, alongside their electrical design study and load analysis.
How Socomec UPS and IPS Technology Secures the Operating Theatre
UPS: Powering the Wider Critical Load
Monitoring stations, imaging equipment, controlled lighting, and building management systems are just some of the critical loads that the Uninterruptible Power Supply feeds. It bridges the gap between when the mains power goes out and when the generator starts up, and in Class 0 configurations, it does this with no break at all.
IPS and the Medical IT Earthing Scheme
The theater’s circuit usually runs on an Isolated Power Supply, which is made up of an isolating transformer that keeps it separate from the main earthed distribution network. If there is a first fault to earth, the medical IT system keeps the circuit running while an insulation monitoring device sounds an alarm. This gives the staff time to finish the procedure safely instead of losing power in the middle of surgery. Socomec’s MEDSYS range, which was designed to work in Group 2 sites, is based on the same medical IT idea.
Socomec’s Operating Theatre Product Range at a Glance
Each Socomec range plays a distinct role in the theatre’s power chain. The table below summarises how they fit together:
| Socomec Range | Function | Typical Use in the Theatre | Transfer Class |
| Masterys / Modulys UPS | Battery-backed uninterruptible power for critical circuits | Monitors, lighting, imaging, control systems | No break |
| STATYS | Static transfer switch between two live sources | Loads that cannot tolerate any interruption | Class 0 |
| ATyS (e.g. ATyS C65) | Automatic / local transfer switch | Class 0.5 critical medical circuits | Class 0.5 |
| MEDSYS (IPS) | Isolating transformer plus insulation monitoring for the medical IT earthing scheme | The operating theatre’s ungrounded circuit itself | Fault-tolerant by design |
Socomec is one of the few companies that can define and support the whole chain, from the incoming three-phase UPS to the isolating transformer inside the theater wall, under one warranty and one commissioning process. This is because they make both UPS and IPS equipment.
DHA, DOH and MOHAP Compliance: What UAE Facility Managers Must Know
The Dubai Health Authority (DHA) is in charge of licensing hospitals and day surgery centers in Dubai. The Department of Health Abu Dhabi (DOH) is in charge of Abu Dhabi and Al Ain, and the Ministry of Health and Prevention (MOHAP) is in charge of the Northern Emirates and sets federal policy. As part of the licensing and commissioning process for a new or refurbished theater, the electrical design is looked at. At inspection, IEC 60364-7-710 compliant documentation for the medical IT scheme and backup power chain is usually asked for.
The number of licensed healthcare facilities in Dubai has grown by more than 8 percent in just one year, and more than 19 million people visit private hospitals across the country every year. As a result, MEP contractors are building several new or larger operating rooms at the same time. It’s better to get the electrical specifications right during the planning phase than during an inspection that goes wrong. This will save you time and money and allow you to hand over the building on time.
Choosing a Socomec Integration Partner in Dubai and the UAE
DCPS Middle East already delivers UPS design, installation and maintenance across hotels, warehousing and other mission-critical UAE facilities, and applies the same rigour electrical design studies, ETAP power simulation, and manufacturer-certified commissioning to Group 2 medical electrical projects.
A qualified partner should be able to run a full load analysis study before specifying equipment, size the STS and ATS transfer switching for the required Class 0 or Class 0.5 transfer, and provide ongoing maintenance so insulation monitoring devices and batteries stay within tolerance for the life of the facility.

Conclusion
You shouldn’t try to save money on the power source for an operating room. A compliant Socomec UPS and IPS specification protects patients, the commissioning schedule, and the facility’s license. This is because of the Class 0 and Class 0.5 transfer requirements in IEC 60364-7-710, as well as the licensing checks done by DHA, DOH, and MOHAP. Every year, the UAE healthcare sector opens thousands of new facilities.
