Mar 29, 2006
Two tiny microprocessor-based MOSFET units offer precision control of small permanent-magnet motors and linear actuators.
Small PM motors or linear actuators need careful control in order to give long life and reliability.
Now Curtis Instruments has released two tiny solutions with the launch of the 1211 and the 1224 microprocessor based MOSFET controllers.
The 1211 is a full quadrant 24V DC fully sealed unit that can supply up to 25A peak current.
If that is too much power then the controller can be plugged in to a PC (with the Curtis 1314 interface kit) and its programmable parameters adjusted.
Besides current limit, maximum speed, acceleration and braking rates are all adjustable.
Installation is made simple with a two bolt fix and pre-attached cables with connectors to reduce assembly time.
The Model 1224 is a 12V unit offering single direction control.
However it can still deliver up to 40A peak and exceeds ISO7176 requirements It also has a rugged metal enclosure (IP54) and boasts features such as power save, HPD and reverse supply protection.
