Key Features

• Gate Power Supply:

  Provides the necessary gate power for one phase of the SCR bridge, enabling effective control of the SCR operation.

• SCR Status Monitoring:

  Monitors the status of the SCRs by collecting voltage information and transmitting it via an optical serial data link to the LCI controller.

• AC to DC Conversion:

  Converts incoming AC voltage to the required DC voltage levels for operational functions.
