MultiMode™ electronic
motor controller.
The 1243GEN2 MultiMode™ controller provides smooth precise control
of motor speed and torque. A full-bridge field control stage is combined with a
half-bridge armature power stage to provide solid state motor reversing and full
regenerative braking without additional relays or contactors.
The controller’s rugged IP53 housing and packaging are built to with-
stand shock and vibration. State-of-the-art surface mount logic board fabrica-
tion makes the 1243
GEN2 controller even more reliable than the original 1243.
The 1243GEN2 is fully programmable through the Curtis 13XX handheld
programmer. In addition to configuration flexibility, the programmer provides
diagnostic and test capability.
