A power transformer is the most common type of custom transformer, often used to convert main voltage to low voltage in order to provide required power to electronic devices and system components. They are available in power ratings ranging from a few mW to MW. The insulated laminations minimizes eddy current losses in the iron core.
Small Power transformers may use a split bobbin, giving a high level of insulation between the windings. The rectangular cores are made up of stampings, often in E-I shape pairs, but other shapes are sometimes used in the design of power transformers.
Dufrane’s Power Transformers are typically either Step Up or Step Down custom transformers, low frequency or high frequency, with many options available including sealing, potting, enclosures, multiple taps, custom connections, mounting configurations, etc.
