AC Tech DEVICENET Ready Sub-Micro AC Drive

AC Tech DEVICENET ready sub-micro drive THE SCD SERIES

With the most features, smallest package and lowest cost for a DeviceNet compatible drive in the sub-micro category, the SCD simply offers the highest value to OEM's and Users that need a DeviceNet ready variable speed drive.
This truly flexible sub-micro drive gives you the compact size you need for your panel layout while delivering on the functions and features your process demands. The SCF Series can be used with 3-phase AC induction motors rated from 1/4 HP up to 30HP (0.18 - 22 kW) on voltages from 120V single-phase to 590 V three-phase.

With 18 isolated terminals (5 logic inputs, 2 logic outputs, 2 analog inputs and 2 analog outputs plus RS485 Modbus Serial Communication), the SCF Series is ideal for motion control applications from the simple to the complex.

Like all AC Tech sub-micro drives, the SCF Series drives employ the EPM memory technology for fast and efficient programming.
