SMC-150, Synchronous Motor Controller

Basler Electric’s years of experience in system excitation control and protection make us uniquely qualified to offer a complete synchronous motor control package. The SMC-150 Synchronous Motor Controller combines the DECS-150 Digital Excitation Control System, the ES-55 Power Factor Relay, and the ES-74S DC Millivolt Sensing Relay - prewired, configured, and tested - as a complete unit for easy installation. This compact solution is extremely well suited for a wide variety of applications up to 10 Adc of excitation current at 55°C.
