Toshiba is the pioneer of transistor based inverter in the world, and also realized the low acoustic motor noise by the sinusoidal-wave PWM control and IGBT device drive. Toshiba has the wide range of inverter from small to large capacity, simple to system use drive. We proudly introduce our newest model, VFS11, VFAS1 and VFPS1.

Fan & Pump control by the inverter

This is the energy saving effect example of a fan & pump by the inverter drive.
The flow amount control ( the water amount control ) by the damper control always requires axial large power because a motor always drives at fixed rotational speed.
However, the inverter drive controls the flow amount by a motor speed control.
The axial power decrease in proportion to the third power of a motor speed, so the large energy saving perform.
