Series AP12 Industrial Control Transformers are designed to comply with industrial and automotive specifications that require the control transformer to be mounted in a separate enclosure, remote from the main control panel. Series AP12 control transformers eliminate the need to purchase a separate enclosure, as these units are encapsulated within a NEMA 12 enclosure suitable for remote mounting. External or remote mounting of the Series AP12 conserves critical panel mounting space and reduces internal control cabinet temperatures, which can be critical to the reliable operation of many solid state, logic, and thermal control devices.
