425 Series Power Controller
The 425 Series comprises SCR power controllers manufactured by Barber-Colman and Robicon. These units regulate electrical power to industrial loads using silicon-controlled rectifier (SCR) technology, providing controlled power delivery in both single- and three-phase configurations.
The series covers a range of voltage and current ratings, including 480V models at 50, 75, and 100 amp capacities, along with 220A three-phase SCR power control units. Model numbers within the family follow the 425-32x designation with various suffixes to distinguish specific configurations.
Common Applications
As SCR power controllers, these units are typically used to manage power to resistive and inductive loads in industrial process equipment.
