Ultrasonic Generators
Ultrasonic Frequency Generator Circuit Board
The Accumax Ultrasonic Frequency Generator Circuit Board is the drive source in an ultrasonic system, converting energy from the power source into the frequency, voltage and current the ultrasonic transducers require.
How it works
The generator is the source that supplies electrical energy to an ultrasonic system's transducers. It receives energy from the power source and converts it to the frequency, voltage and amperage the application requires. Output frequency is selectable across 18.8-45.6 kHz and can be locked or unlocked from the on-board controls; in cleaning duty, increasing the frequency produces a smoother cleaning process.

5 further specification s are listed in the datasheet but not reproduced here
These labels appear in the datasheet, but the value beside them could not be read reliably from the document. Rather than print a figure we cannot stand behind, we have left them out — ask us and we will confirm them directly.
- Operating Voltage Range — GENERAL SPECIFICATION > POWER SUPPLY: the label is printed but its value cell is empty in the text layer (the separate Hardware Specification list gives '5V DC' as the device operating voltage, which is recorded above; the range itself is lost)
- Storage Temperature — GENERAL SPECIFICATION > ENVIRONMENTAL: label present, value cell empty
- Operating Temperature — GENERAL SPECIFICATION > ENVIRONMENTAL: label present, value cell empty
- Switch header number — section 5 note reads 'These switches are connected with J header'; the header number is lost (the output pins are separately identified as J9)
- Per-band lock / Q1 / Q2 states — the table under each frequency selection (4.1-4.4) and in the GENERAL SPECIFICATION prints only the column headings 'lock Q1 Q2 lock' and 'On/Off'; the cell contents that would say which switch is on or off for each band are lost
Applications
- Ultrasonic cleaners
- Ultrasonic welding machines
Frequently asked questions
What frequency range does the generator board cover?
18.8 kHz to 45.6 kHz. It is a multi-frequency generator rather than a fixed-frequency one.
What supply voltage does the board need?
The device operating voltage is 5 V DC.
How big is the board and what does it weigh?
72 x 46 x 30 mm, weighing 60 g.
Can the frequency be fixed once it has been set?
Yes. The board has a frequency lock/unlock configuration.
Why would I want more than one frequency?
In cleaning applications, different frequencies and powers deliver different cleaning intensities - increasing the frequency gives a smoother cleaning process. A generator that produces different frequencies therefore suits varied cleaning applications.
What is it used for?
Ultrasonic cleaners and ultrasonic welding machines.
