Piezo Driver MTAD1030

Instruction Manual1

Overview
Piezo Driver MTAD1030 amplifier is specially designed for pulse drive. It is capable to drive

piezoelectric actuators at high speed by amplifying input waveform applied on the piezoelectric
actuator, flowing a large peak current corresponding to the steep waveform of the rising edge andthe falling edge.
It runs on a 100V AC power supply and is stored in a portable storage case that can be carriedaround. Piezo Driver MTAD1030 is designed to be easily operated.

4Operating Method

4.1 The following are the operational parts on the front panel.
[POWER ON]: Connection switch of the AC100V power supply.
[OVER L]: When the overcurrent protection circuit is activated, light indication will occur.
[RESET]: Push button switch to restore/reset when the overcurrent protection circuit lightindicator is on.

The following are the operational parts on the back panel.
[AC 100V]: Connection outlet of 100V power supply.
[OUTPUT]: Output plug[R]: Terminal that connects the resistor(4Ω) in series[GND]: Tto ground the case and internal circuit of the instrument with the ground terminal[MONITOR]: 1/10 level of the monitor plug output[INPUT]: Signal input connection terminal[BIAS]: Semi-fixed regulator for operational settings[GAIN]: Semi-fixed regulator for amplification degree settings.

Back panel terminal connection

Precautions
There is a 1.5Ω resistor internally at the Output terminal [OUTPUT].
When the capacitance of the piezoelectric actuator is small, and low applied voltage is used, thereare possibilities of achieving high speed drive.
For resistant of 1μF above, [R] terminal (4Ω connected in series internally) is recommended.
Operation method
1) Voltage output is being supplied to the load when the [POWER ON] switch on the front panel ison.
2) The [INPUT] terminal at the back panel is set to connect the control signal in order to achieve
output with gradually increasing amplitude.
3)【Regarding the overcurrent protection circuit】
There is a protection circuit in the power supply part of this MTAD1030. The following
settings were done to avoid short circuit caused by overload or malfunction due to operation
miss.
Average current ≒120mA
Peak current ≒25A
When protection circuit is triggered, press the button after resolving the cause.
The protector may become faulty if the activation and resume is continuously repeated.

Operating precautions

This MTAD1030 may raise the drive frequency utilizing maximum amplitude until the average
current protection circuit is activated, but it will generate heat at the same time. It isrecommended that a fan or any ventilation device is being used to reduce heat. Please be notedthat significant heat generation occurs under normal operation. Please use MTAD1030 withproper ventilation.
Please contact us (info@mechano-transformer.com) if any unexpected situation occurs regardlessof the above.
