Profile: Dongan Electric Mfg. Co. is a manufacturer of transformers and other power quality equipment. Our product line includes single, three, buck boost, energy efficient, single phase CE, motor drive isolation, and energy efficient transformers. We also provide DONGAN™, GEOTRAN™ and SUPRASPARK™. Our DONGAN™ transformers are shipped as low voltage isolation transformers that can be easily reconfigured to buck or boost a wide range of voltages. These transformers are easily adaptable to most minor voltage corrections that need to be made and are an inexpensive solution to isolation transformers. They are physically smaller and lighter than the corresponding kVA of an isolation unit. The 2 kva buck boost transformer can do the work of a 7.5 to 32kva isolation unit depending upon how it is configured. These will work on single or three phase applications. We offer these on 85 series which is encapsulated and 115°C rise, 80 series which is ventilated and 115° C rise and 35 series which is also ventilated but with a 55° C rise. Our industrial oil and gas ignition transformers along with transformers are for residential oil burners. Our solid state igniter in 2005 is for the residential oil heat market. We refer to this product line as the SUPRASPARK™ and they can be used on all major OEM burner manufacturers. We offer these as universal mount or completely fitted for the burner.
