VF-AS1 Series

The AS1 Adjustable Speed Drive builds on Toshiba's history of supplying powerful, reliable and versatile drives. 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. The AS1's advanced features and new technologies make it the new contender in the PWM control drive market. 

The VF-PS1 is the variable frequency inverter for variable torque and low peak torque applications, such as fan, pump and HVAC for industrial markets.
New function of "Advanced energy-saving" mode minimize the loss of induction motor in the low speed.
