Features
The SG-112.5KVA three-phase dry-type transformer features a flexible multi-tap design on its input voltage system, offering precise voltage adjustment capabilities. With 2x2.5% FCAN (full-load current above nominal) taps and 6x2.5% FCBN (full-load current below nominal) taps on the 240Y/139V primary winding, it enables a total adjustment range of ±20% to accommodate fluctuating grid conditions or specific load requirements.
This tap configuration ensures stable power conversion by allowing fine-tuning to maintain optimal voltage levels, enhancing compatibility with diverse power sources and improving system reliability in dynamic electrical environments.
