Curtis Series MOSFET electronic controllers provide cost-effective speed and braking control. High-frequency switching and ultra-low voltage drops provide very high efficiency, and smooth, silent operation.

Models 1231C/1221C
The Curtis PMC models 1231C and 1221C motor speed controllers provide smooth, silent, efficient and cost effective speed control for on-road electric vehicle applications. These controllers utilize power MOSFET technology, pioneered by Curtis PMC, to provide benefits unavailable with older speed control systems.
