 Issue:
Is external control power required for control voltage with the enclosed 8638 and 8639 ATS48 Softstarter?
 
 Product Line:
Altistart 48
  
Environment:
All
 
 Cause:
Altistart Soft Starter with Control Power Transformer (CPT) 
 
 Resolution:
No, a Control Power Transformer (CPT) with 120VAC secondary is included as standard on enclosed ATS48 products. This provides enough power to operate the included control relays and contactors as well as the control power for the soft starter.
