Microprocessor-controlled generators LG supply the required HF power up to 9000 watts for the operation of ultrasonic oscillating systems and ultrasonic cleaning devices. As standard, the connection is made with Quick Connect technology. All modules in the LG generator can be conveniently inserted from the front without any conversions or reprogramming.

Module generators LG

The microprocessor-controlled ultrasonic generators LG deliver HF power up to max. 9.0 kW at 25 kHz or 40 kHz. The selection of the generator with power and modules depends on the total output of the ultrasonic the ultrasonic oscillating systems to be connected and the desired controllability of the application. At the heart of the ultrasonic generators are power modules up to 1.5 kW with control of all operating parameters by a microprocessor on board.

Operating and power modules for LG generators

SM 3 control module

Stepless adjustment of the target power 10-100% via rotary control & START-STOP switch for switching the HF output on/off

Processor module PRO 3

Individual programming of individual power modules, degassing function & error display

Power modules M 1003 & M 1503

LEDs signal the operating status, module switch for individual activation of power modules, power stability ± 2% and open-circuit, short-circuit and overload-proof. overload-proof


To increase the generator output, additional power power modules are simply inserted into free slots slots. Mixed configurations with modules of different frequencies (25 or 40 kHz) and outputs are possible.


All modules of the LG generator can be conveniently inserted and replaced from the front. The settings are made via the SM 3 or PRO 3 operating modules. The power is output via the power modules M.


The rear connections for the remote control and the RS 232 serial interface allow the generators to be integrated the generators into higher-level monitoring and control systems.

Compact generators TG 1503 and
TG 3003 - especially for plant engineering

The microprocessor-controlled ultrasonic generators TG 1503 and TG 3003 deliver HF power up to max. 3.0 kW at 25 kHz or 40 kHz, with TG 3003 a mixed configuration is also possible.

The compact design enables installation in a standard control cabinet, and wall mounting is possible using mounting brackets (optional).

Generator & PLC

RS 232 interface for PLC or PC

The generator can be integrated into higher-level control and monitoring systems via the interface. The modules are controlled directly by the PLC.

Customised equipping with ultrasonic oscillating systems

Tubs, basins, plates, flanges, pipes and other metal assemblies are fitted directly with ultrasonic transducer systems for cleaning purposes or other sonication tasks if the use of immersible transducers or flat transducer plates is not possible. The transducer systems are bonded to the outer surfaces in such a way that the sound effect is directed into the liquid or onto an object in the liquid.

Project planning notes
The intended mounting surfaces must be flat. The power per ultrasonic transducer system is max. 50 watts. The transducer systems can be fitted with an aluminium cover (degree of protection IP 20), which provides protection against contact but not against splash water.
