1 — OVERVIEW
OVERVIEW
Curtis PMC 1223/33, 1225/35, and 1227/37 MultiMode™ controllers are
programmable permanent magnet motor speed controllers designed for use in a
variety of small electric vehicles. These controllers extend the capabilities of the
1208, 1203A, and 1213 families for applications where greater functionality or
programmability is desired.
The series includes Models 1223/33 (card only, 24–36V), Models 1225/35
(sealed case, 24–36V), and Models 1227/37 (ABS cover, 24–48V).
The 122X models (1223/25/27) are designed primarily for use in mobility
aids, scooters, and other small personnel carrier applications. The 123X models
(1233/35/37) offer additional features for industrial applications and are typi-
cally used in scrubbers, AGVs, small walkies, etc.

MultiMode™
electronic motor
controllers, with 1307
handheld programmer.
The corresponding
123X models (1233,
1235, and 1237) are
externally identical to
the 122X models but
have additional built-
in features.
The 1223/33, 1225/35, and 1227/37 MultiMode™ controllers offer smooth,
silent, cost effective control of motor speed and torque. A four quadrant, full
bridge power output stage provides for solid state motor reversing and full
braking power without additional relays or contactors.
These controllers are fully programmable by means of the optional handheld
1307 programmer. Use of the programmer offers diagnostic and test capability as
well as configuration flexibility.
