ULTRASONIC WELDING
Power Supply for Automation
The ultrasonic generator, A series of Covonics,
is designed with PLL circuit that enables digital tuning and digital amplitude control on the front panel. This is used for continuous operations and automation production line.
Key Features
Internalization of System Protection
Monitoring (SPM)
Monitoring (SPM)
1) Phase Changing 2) Over Voltage
3) Over Current 4) Heating Overload
5) Power Overload
3) Over Current 4) Heating Overload
5) Power Overload
Maintains converter amplitude by regulating for variances in the line voltages and Maintains converter amplitude over the full range of rated power.
Autotune and Frequency Memory
Automatically adjust frequency within error range for each frequency.
Updates horn frequency memory at the end of each weld and memory frequency can be reset by external reset.
Updates horn frequency memory at the end of each weld and memory frequency can be reset by external reset.
Selectable ramp up time to reach the max amplitude
Provides four starting ranges. Select Start allows the Power Supply to ramp up amplitude at different rates to accommodate different horn and load requirements. 10, 30, 80, 100 ms
Bar graph on Front panel- During a weld cycle, shows the true percentage of ultrasonic power in use.
Digital amplitude change
1) Front Panel 2) External Source
Auto seek
Track Horn frequency at low amplitude and store in memory
1) Seek on power-up
2) External Control
3) Seek by “Test” key on Front panel
4) Checks horn frequency once each minute
