Whirlwind’s PLR-MC21 and PLR-MC22 (pictured here) control three-phase chain motors. Each will operate one or two motors in a 2RU package, with all controls and connections accessible on the front panel. The PLR-MC21 has 10-amp circuit breaker protection and is designed for use with one-ton and smaller motors. The PLR-MC22 has 20-amp circuit breaker protection and is designed for use with two-ton motors. Both have individual up and down selectors for each motor and a master GO button. A phase reverse circuit is also provided to correct motor direction. Three phase input connectors can be selected to coordinate with existing power distros.
