DCP-I Control Board
The DCP-I Control Board controls the following functions of the power supply:
• Responding to start and stop signals
• Responding to alarm and reset signals
• Responding to user input
• Controlling and monitoring ultrasonics
• Providing information for the Front Panel LCD
• Generating alarms
• Controlling communications
• Storing operating frequency of last weld (frequency memory) and using the stored frequency as
a starting point for the next weld
• Checking and updating frequency memory on start-up
• Providing starting ramp times (Start)
• Provide a standard interface for automation (26-pin HD D-Sub Connector)
LCD Board
The LCD Board controls the Front Panel LCD interface and communicates user input to the
DCP-I Control Board.
Ultrasonic Power Supply Assembly
The ultrasonic power supply assembly generates ultrasonic energy at the resonant
frequency of your converter-booster-horn (stack). The ultrasonic power supply assembly
contains three main circuits.
• 320 VDC Power Supply: converts AC line voltage to +320 VDC for the output power devices.
• Output Circuit: Matches the impedance of the output power device to the converter-booster-
horn stack; and provides feedback to the control circuit.
• Interface Circuits: perform the following functions:
Provide drive signal to output power device
Determine true percentage of ultrasonic power used over a range of amplitudes
Allow control of the resonant frequency
Control starting amplitude
Provide overload protection for the ultrasonic power assembly
Line Filter
The line filter performs the function of providing RFI filtering for the line voltage input to
the power supply. The filtering also blocks ultrasonic signals from entering the AC main
line.
24 VDC Power Supply
The 24 VDC power supply pr24 VDC for the DCP-I control board, LCD board, user
I/O signals, and DC fan.
