More Information

Toshiba’s heavy duty S15 adjustable speed drive is a compact and high performance drive designed for controlling a wide range of variable and constant torque applications. This micro-drive is capable of working with permanent magnet (PM) motors, which allows a greater flexibility in selecting a motor for an application and optimizes energy savings. A robust design allows the S15 to operate in extreme temperatures and environments. In addition, the S15 features advanced technologies, and an expanded PID control allows a greater level of precise control and operation of difficult level control applications. No other micro-drive delivers such reliable and extreme performance with extensive capabilities at such a competitive cost.
