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 for 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. The S15 is one of the most compact drives available on the market. This drive makes a fantastic choice if footprint or price is an issue for the end user as it still offers heavy duty ratings through a 150%/60s overload rating and up to 60C ambient temperature.
