DEWEN™ – UK UPS Systems
At DEWEN™, we are proud of our UK engineering heritage. Most of our UPS systems are designed and manufactured in Britain. The remainder are tested and validated in our UK facilities, ensuring they meet the same strict quality and compliance standards.
Scalable and Flexible Power
Our portfolio ranges from compact single-phase units to multi-megawatt three-phase systems. We provide flexible battery chemistries, IP ratings up to IP66, and advanced monitoring technologies. This adaptability allows us to deliver tailored UPS solutions for each sector.
In many critical installations, UPS solutions operate alongside DC power systems→ to support mixed AC and DC loads.
Supporting Critical Sectors
We serve industries including healthcare, utilities, telecoms, transport, energy, and industrial infrastructure. Moreover, all our systems comply with BS EN, IEC, WIMES 3.07, CE marking, and EMC/EMI directives. As a result, our customers gain reliable, compliant, and sustainable power continuity.
UPS Solutions for Every Industry
Because our systems are based on British engineering and sector-focused design, they provide long-term resilience. Consequently, each of our product families is built to deliver dependable performance in its own application.For applications requiring flexible energy transformation, our UPS platforms integrate with advanced power conversion systems→.
