Dale’s Three-phase UPS systems typically cover larger installations such as data centres, industrial and manufacturing facilities, and hospital environments.
Transformer-based UPS systems are widely regarded as the most robust and resilient form of UPS technology, particularly in larger and more demanding applications. Their integrated transformer provides galvanic isolation between the input and output supplies, creating a physical separation that protects critical loads from electrical noise, voltage transients, surges, and other power quality disturbances originating from the mains supply.
Typically deployed in installations above 100 kVA, transformer-based UPS systems are often the preferred choice where maximum reliability, fault tolerance, and power protection are required. The transformer enables independent mains arrangements, enhanced protection against DC voltage faults and backfeed conditions, and delivers higher short-circuit current capability to support downstream protective devices during fault conditions.
These characteristics make transformer-based UPS solutions particularly well suited to critical infrastructure, industrial processes, healthcare facilities, transportation systems, and other environments where power continuity is essential. While they are generally larger and less efficient than transformerless alternatives, their superior electrical isolation, fault-clearing performance, and proven robustness continue to make them the technology of choice for many mission-critical applications.
Offering products rated from 10kVA to 800kVA, our Transformer based Three-phase output UPS range offers an efficient, robust, and configurable solutions for every application, regardless of the technical or commercial requirements.
