Toshiba AS1 Drive is a heavy-duty, general-purpose adjustable speed drive (ASD) designed for a wide range of industrial applications. It’s designed to handle tough applications and withstand challenging operating conditions.
Features
The AS1’s advanced features and new technologies make it the new contender in the PWM control drive market. The modular construction of the AS1 allows the unit to be installed into nearly any application quickly and easily. The drive can operate with little or no programming. At the same time, the AS1 maintains one of the most expansive parameter sets in the industry. Its sealed cabinet design, new PID algorithm and motor-over-flux-braking technology make this drive adept to handle the most difficult applications.
- Advanced Design: The modular construction of the AS1 allows the unit to be installed into nearly any application quickly and easily.
