Reliable UPS systems designed for critical infrastructure
At DEWEN®, we design and deliver advanced Uninterruptible Power Supply (UPS) systems engineered in the UK. Our solutions support critical power applications where reliability, flexibility, and performance are essential. We combine British engineering expertise with modern technology to meet the demands of today’s power environments.
Our UPS portfolio includes compact single-phase units, high-capacity three-phase systems, and fully modular architectures. This wide range allows customers to select solutions that match their exact operational needs. Typical applications include telecom networks, substations, oil and gas facilities, data centres, transport infrastructure, and industrial sites.
DEWEN integrates IoT-enabled monitoring and intelligent diagnostics into its UPS platforms. These features provide real-time system visibility and early fault detection. As a result, operators can improve maintenance planning, reduce downtime, and maintain full control of their power assets.
All DEWEN UPS systems are designed to meet recognised British and international standards, including IEC/EN 62040. We also operate in line with ISO-certified quality, environmental, and health and safety management systems. Each solution undergoes rigorous testing, including Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT), before commissioning.
Beyond the technology, DEWEN adopts a collaborative and consultative approach. We work closely with engineers, consultants, and asset owners from specification through to commissioning and ongoing support. This ensures every UPS system delivers dependable, compliant, and future-ready performance.
By choosing DEWEN, customers gain a trusted partner for critical power solutions. Our UPS systems combine advanced technology, tailored design, and proven engineering standards to support long-term operational resilience.
