The Dean 807-4978 dual transformer converts incoming electrical voltage for control circuits in compatible commercial fryer equipment. Its specified 100/120V input and 12/24V output ratings identify the voltage configurations supported by this component. By providing lower-voltage power to connected control components, it supports their electrical operation within the fryer system. https://partsfe.com/807-4978-frymaster-transformer-vf-dual-100120v-1224v/1-807-4978.html
