Curtis Controllers Model 1210

The MultiMode motor speed controller from Curtis Controller Model 1210 is used for permanent magnet (PM) motors. 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 a silent and cost-effective controller utilized to control the brake, torque, and speed of the motor.

The Curtis 1210 is fully programmable and operates at a frequency of 15 kHz, a nominal voltage of 24 volts, and a current rating range of 45-70 amperes. This controller guarantees an optimum driving experience with premium parameter control. It provides a better driving experience due to its features and it is a highly reliable controller as it automatically monitors components to ensure a safe start and rejects input if the system is faulty.

The Curtis 1210 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.
