Starters, Low Voltage
SMC-50 Soft Starters Now Available with Internal Bypass
This new offering combines the advanced functionality of the SMC™-50 control platform with the energy savings capabilities of an internal bypass power structure. After the motor has been started and reaches full speed, the controller closes the internal bypass contactors which increases energy efficiency and reduces heat output. This results in:
- Reduced enclosure size
- Reduced cost, avoiding the need for external bypass contactors
The SMC-50 fully solid-state unit continues to be available with normal and heavy duty ratings for customer flexibility in difficult and demanding applications.
