Curtis Controllers Model 1228

The MultiMode Curtis 1228 is a controller utilized for speed control of permanent magnet (PM) motors and it is designed to operate silently and efficiently. Due to the four-quadrant, full bridge power output stage, it is not necessary to add relays and contactors to reach full braking and motor reversing power. It is also fully programmable through the programming device by Curtis where one can perform parameter configuration, diagnosis, and testing of the controller.


The controllers from Curtis 1228 have an operating frequency of 15 kHz with nominal voltage options of 24 and 36 volts and current rating range of 70 to 110 amperes. These specifications made the controller ideal for small electric vehicular applications such as scooters. The controller also guarantees optimal driving experience due to its premium parameter control with other key features such as speed control, cutback functions, Key Off Deceleration, E Stop, reverse beeper, and push-too-fast feature, among others.


The Curtis 1228 controllers can now be purchased here in Cloud Electric, your one-stop shop for all your electric component needs. Cloud Electric is a leading distributor of electronic components in North America. We take pride in our informative product descriptions, pricing, and shipping speed.
