Trane TRR1827 Transformer Els PW 17895 If the pilot light ignitesThe Trane TRR1827 Transformer is a critical OEM Choke Line Transformer (also referred to as a bell transformer) engineered specifically for high performance HVAC voltage regulation. Unlike standard step down transformers, this choke line transformer is designed with high inductive reactance to limit inrush current during the initial equipment startup phase. This electrical dampening effect protects sensitive control boards and high value components
