Product Overview: The Dayton 2Z846D is a 0.75 HP variable speed DC motor drive designed to control DC motor speed in industrial applications. It regulates motor speed through SCR-based control circuitry, providing adjustable DC voltage output up to 90VDC. This drive is typically used in paper handling equipment and light industrial machinery requiring precise speed control. The unit operates from AC line voltage and includes protective fusing. It is sold without an integrated motor and must be paired with a compatible DC motor for operation.
