Baldor Electric Co.: Digital Soft Starter
The MST soft starter with six SCR three-phase voltage control offers advanced protection for the motor, soft starter, and load, ensuring trouble-free operation, the company said. Available from 7.5-1,000 hp at 208-575 vac, the product can be used in a wide variety of applications including pumps, compressors, fans, conveyors, mixers, and stirrers. The soft starter features programmable torque control, providing a more linear acceleration during start that reduces wear and tear, and during stop, virtually eliminates pump-water hammer, according to the manufacturer. The company stated, the torque control function was developed and tested in collaboration with pump manufacturers to ensure the best possible stop without water hammer and pressure surges. Features include integrated advanced motor protection with current sensing, programmable signal relays, programmable analog output, and a built-in keypad interface. MST Digital Soft Starters are available in two styles: an open starter or an enclosed combination starter. The open starter has a smaller footprint that makes mounting easy, and is loaded with high-end features that improve performance and save energy, stated the manufacturer. The enclosed combination starter combines overcurrent protection and overload protection in a single package.
