Dale’s Three-phase UPS systems typically cover larger installations such as data centres, industrial and manufacturing facilities, and hospital environments.
Transformerless UPS systems remove the need for a large, heavy, and heat-generating transformer, resulting in a more compact, lightweight, and energy-efficient solution. Their higher operating efficiency reduces both power losses and cooling requirements, delivering lower installation and lifetime operating costs when compared to traditional transformer-based designs.
The primary limitation of a transformerless UPS is the reduced level of electrical isolation and fault-clearing capability compared to a transformer-based system. While external isolation transformers can be added to overcome this, doing so increases cost, footprint, complexity, and maintenance requirements, reducing many of the benefits that make transformerless technology attractive.
For higher power ratings and redundancy requirements, transformerless UPS systems often rely on multiple modules operating in parallel. Although modern modular systems are highly reliable, increasing the number of components inevitably adds complexity and creates additional potential points of failure within the overall system
Offering products rated from 10kVA to 200kVA, our Transformerless Three-phase output UPS range offers an efficient, robust, and configurable solutions for every application, regardless of the technical or commercial requirements.
