OVERVIEW
Curtis 1204M, 1205M, 1209M, and 1221M series motor controllers are the
form/fit/function replacements of the earlier 1204/1205/1209B/1221B con-
trollers, with the added functionality of being programmable—via a Curtis
handheld programmer or PC programming station. This means the controllers
can be tailored to the needs of specific applications. In addition to configuration
flexibility, use of the programmer offers diagnostic and test capability.
These controllers are the ideal solution for a variety of electric vehicle
applications, including industrial trucks, personnel carriers, material handing
vehicles, light on-road vehicles, golf cars, etc.
