Product Description
Pluto is a high performance closed loop servo drive controller suitable for DC brushed, steppers, voice
coils and brushless motors.
Its design includes multiple communication ports, enabling thus a wide choice of interfacing methods. Its
extended voltage operating range allows its use in several applications, and the small footprint and the
needless of an external heatsink allow the controller to be a valid OEM for critical-size applications.
The design also includes a wide variety of self protection mechanisms.
