How PSE and Socomec Support Dublin Data Centre

In a data centre environment, power continuity is not optional, it is fundamental. Every maintenance decision must protect uptime, preserve resilience, and minimise operational risk. When infrastructure is supporting critical digital operations, even a planned intervention demands precision, control, and absolute confidence in execution.

That is exactly where the partnership between PSE and Socomec delivers value.

At a Dublin data centre, PSE and Socomec worked together to support the ongoing reliability of a 320kVA UPS system, combining trusted UPS technology with safe, structured service execution and long-term maintenance capability. The result was a carefully managed intervention designed to protect performance in one of the most demanding operating environments possible.

The Challenge: Maintaining Critical Power System Without Compromising Continuity

In data centres, UPS maintenance is never a routine task. It must be carried out in a live, high-availability environment where risk tolerance is low and operational expectations are high. The challenge at this site was to complete essential maintenance works on a UPS system while ensuring:

• Safe execution under controlled site conditions
• Minimal operational disruption
• Continued confidence in critical power resilience
• Full documentation and compliance throughout the intervention
• A successful return to service following component replacement and testing

For data centre operators, this is the real challenge of critical power, not simply replacing parts, but doing so in a way that protects uptime, supports resilience, and maintains trust in the infrastructure behind the operation.

The Solution: A Structured, Safety-Led UPS Maintenance Intervention

Working in partnership, PSE and Socomec delivered a planned maintenance solution aligned with the operational requirements of a mission-critical data centre. The project was delivered through a structured service approach designed to ensure the UPS system was:

• Managed through a safe and structured maintenance process
• Handled in line with site, safety, and operational requirements
• Tested before being returned to service
• Supported for continued reliability in a mission-critical environment

This was not simply a service visit. It was a controlled critical power intervention engineered to maintain operational integrity at every stage, from planning and shutdown to replacement, testing, and return to service.

Socomec: Trusted Technology for Critical Resilience

DELPHYS Green Power

Designed for mission‑critical environments, Socomec DELPHYS Green Power UPS solutions deliver maximum availability, flexibility, and industry‑leading energy efficiency for modern data centres.

For data centres, power continuity is not only a technical requirement but a core condition for business reliability. The DELPHYS range is engineered to support critical applications where uptime, efficiency, scalability, and serviceability are essential.

A key advantage of DELPHYS Green Power technology lies in its strong environmental performance. With ultra‑high efficiency of up to 96% in true double conversion mode and up to 99% in energy‑saving modes, the system significantly reduces energy losses, operating costs, and associated CO₂ emissions. This enables data centre operators to improve sustainability while optimising total cost of ownership, in line with increasingly stringent environmental and energy‑efficiency standards.

The innovative 3‑level topology ensures high efficiency without compromising power protection, while the kW=kVA design allows full rated power delivery without oversizing, contributing to lower material usage and improved resource efficiency. Its compact and optimised design reduces footprint and infrastructure requirements—an important advantage for data centres where space and cooling efficiency are critical. High‑efficiency operation also reduces heat dissipation, further lowering cooling demand and overall energy consumption.

The system supports both N and N+1 redundancy, helping operators enhance resilience against unexpected failures. Combined with advanced monitoring and maintenance features, DELPHYS ensures reliable, efficient, and sustainable operation throughout its lifecycle.

PSE: End‑to‑End Engineering for Critical Resilience

Technology is one part of the answer. In mission-critical environments, long-term performance depends on how that technology is engineered, delivered, supported, and maintained in real operating conditions.
That is where PSE’s end-to-end engineering expertise makes the difference.
From initial planning through installation, commissioning, maintenance, and ongoing optimisation, PSE supports data centre operators with a full-service approach designed around reliability, resilience, and operational confidence.
PSE’s value goes beyond execution alone. It comes from the ability to combine technical understanding, practical delivery, and responsive support into one joined-up service model.
In mission-critical environments, that combination of trusted technology and expert local support makes a measurable difference.

For data centres that demand certainty, PSE delivers confidence.
