Drive targets: stacked piezoelectric actuators, bimorphs, unimorphs
- Amplification rate: 50 times (customizable) - Output range: -20V to +150V - Output average current: 2A - Example of drive targets: stacked piezoelectric actuators, bimorphs, unimorphs - Example of applications: punchers, precision stages, pumps, valves, precision grippers - Dimensions: W360 x D300 x H185 mm - Power supply: AC100V Operation description: This device uses a MOS-type FET in the output stage to form a quasi-complementary amplifier, achieving stabilization of amplification and low noise wideband characteristics through a negative feedback circuit. The input signal is buffered and enters the gain adjuster for gain setting. Meanwhile, the bias voltage generated by a temperature-compensated reference voltage generator can be set to an arbitrary value using a bias voltage adjuster and is added to the aforementioned signal before entering the output amplifier. The output amplification section receives the input signal through an operational amplifier, and to achieve high output, four MOS-type FETs are connected in parallel, further reducing impedance through a quasi-complementary circuit. Negative feedback is achieved by returning an inverted signal to the operational amplifier in the input section, and the output terminal is designed to cut off the output in case of overcurrent protection.

Company information
"Mechatrans" is a technology that I developed during my time at NEC in the 1980s, successfully realizing the world's first and fastest piezoelectric impact printer at that time. Subsequently, due to the evolution of printer technology, this technology disappeared from the public eye. However, Professor Toshio Higuchi from the University of Tokyo foresaw the potential of this technology, leading to the establishment of today's company. By leveraging the numerous advantages of the piezoelectric method, "Mechatrans" has achieved high-speed and large-displacement actuators, and I feel the potential for its use in a wide range of fields. We have now developed a series of actuators for everyone’s use.
