Digital Ultrasonic Power Supply for Ultrasonic Cutting / Welding / Sealing Machine
What’s ultrasonic 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.

lease operate this equipment by professionals person, otherwise it will cause irreparable damage.
1. High voltage will be generated inside the device. To ensure safe use, pay attention to the following
• Do not use this product when the housing is open.
• Do not excessively impact or crush the device.
• Use a grounded power supply to avoid possible electrical shock.
· Do not put your hand under the welding horn. The welding horn pressure and ultrasonic vibration will
• Do not operate the equipment when the transducer and mold are not connected, to avoid unnecessary
damage to the equipment.
• When replacing large molds, be sure to keep yourself safe.
·Before using, be sure to check if the mold is loose. Never operate the equipment with the mold loose.
· When an abnormal condition occurs, the fault is not resolved. Do not turn it on again to avoid the fault
• Due to the large number of electronic components inside, whenever you dispose of this device or
replace internal parts, be sure to follow the laws and regulations in your area.
Equipment work environment requirement.
Maximum allowable environment temperature: -20C° to 40C° Exceeding the operating temperature
may cause work error and fire.
Maximum allowable air humidity: less than 70%. Excessive air humidity can condense water inside,
Short-circuit the internal electronic components of the power supply, causing the device to operate
Maximum electromagnetic interference intensity: less than 120E. Larger than this standard can
seriously interfere with the normal operation of the device and damage the device. Ultrasonic power
supply itself is a large source of electromagnetic radiation. When there is a clear electromagnetic
interference and multiple devices are tightly installed, all communication lines and energy output
cables should be shielded and coaxial.
POWER SUPPLY REQUIREMENT:
The power input standard is: single phase AC220V 50HZ/60HZ.
Input power supply voltage fluctuation range: <10%.
Input power grid harmonic content: <20%.
Input supply current: <20A.
Input power cable diameter: >2.5MM2.
Equipment wiring diagram:
There are two parts of this equipment that need to be wired by the user. The wiring is as follows:
1, the fan.
2. Power switch.
3. Transducer interface (The transducer interface uses a single-core high-voltage RF interface, the
center line is the positive end of the transducer, and the shield is the negative end of the transducer). (It
is strictly forbidden to reverse!)
4, DB9 female interface, this interface uses the conventional DB9 core wire connection, the adapter
board is attached to the random device, and the adapter board connection method is shown in the wiring
5, power socket (character type interface).
6, fuse holder (this device uses 15A, 250V fuse).
1, DB9 female seat, this port is connected to the base of the power supply sound through the DB9 core
2, 24V power supply terminal, this port provides a constant voltage of 24V, the maximum current of
3. This port is a pressure trigger port. This port is valid when the device works in pressure trigger mode.
4, Solenoid valve interface, can be connected to the voltage 24V, the maximum power of 5W solenoid
5, Automatic operation start and emergency stop wiring port.
