generator?Ultrasonic generator, usually called ultrasonic power
supply. Its function is to convert our mains (220V 110V or
380V, 50 or 60Hz) into a high frequency AC signal that matches the
ultrasonic transducer. From the form of the amplifying circuit, a
linear amplifying circuit and a switching power supply circuit can
be used, and the high-power ultrasonic power source generally
adopts a circuit form of a switching power supply in terms of
conversion efficiency. Linear power supplies also have their own
application range, which has the advantage that the circuit can be
not strictly required.Matching allows the operating frequency to
change continuously and continuously. From the current situation in
the ultrasound industry, ultrasonic generators are mainly divided
into self-excited and separate excited power supply.The
principle of the ultrasonic generator is to first generate a signal
of a specific frequency by a signal generator, which may be a
sinusoidal signal or a pulse signal. This specific frequency is the
frequency of the transducer, and is generally applied to ultrasonic
in an ultrasonic device. The frequency is 20KHz, 25KHz, 28KHz,
33KHz, 40KHz, 60KHz,70khz, 100KHz.With best PZT8 in China The
impedance of the transducer is less than 8 and the impedance of the
transducer and welding horn is less than
40. 5times test for ultrasonic check 3hours Temperature
rise detection To confirm all your transducer with horn no
matching problem. The ultrasonic signal generator is composed
of an ultrasonic power amplifier module that can convert 50/60 Hz
industrial frequency alternating current into super audio frequency
for the transducer to work, and a control module with "system
protection monitoring" and "auto-tuning" functions. The control
module can cut off the ultrasonic energy when the ultrasonic
welding work fails, thus providing extremely high safety and
reliability for the generator and the entire welding
equipment.1. Really automatic frequency tracking (AFC) adapts
to various sizes of welding molds and different design molds. The
frequency range of automatic tracking: ±400HZ (according to 15KHZ
ultrasonic for example, the mold frequency can be used for
automatic frequency tracking at 14.40-15.20KHZ). Frequency tracking
accuracy: ±5HZ2. Adopt CPU computer to monitor each program
with fast speed, strong adaptability, built-in
various protection systems, "system protection monitoring"
function will respond to the following situations:
Excessive pressure leads to overload
Ultrasonic generator current is too
large Welding head, horn or transducer loose or other
failure Generator circuit failure Faulty cable between
generator and transducer Automatic compensation for unstable
power supply frequency3. The "automatic tuning" function
enables the ultrasonic generator to automatically track and
compensate for changes in the welding head frequency. When the
temperature is too high, the surface of the welding head is
worn or there is debris on the welding head, this frequency change
will occur.4. Built-in fully automatic constant amplitude system,
which can automatically compensate for different air pressure
changes and voltage fluctuations,and can adjust the ultrasonic
amplitude from 50% to 100% steplessly to meet the requirements of
different welding workpieces.5.Using IGBT for power amplification,
the response is fast, which is more than 100 times faster
than the traditional silicon power tube, so the protection
function is better. Voltage: 198-242VAC (50 / 60Hz), the
output will be much weaker when AC110V input, need some adjustment,
direct use is almost only used for cutting applications.Volume:
