Matsusada Precision
3-1 Overview
This product is a piezo driver power supply that is designed optimally for driving piezo elements. At
startup, the output current is increased up to three times the rated value so as to respond at high speed.
It is also equipped with full protection functions to prevent damages to the elements.
3-2 Features
This unit is a large peak power piezo driver. The peak current is three times more than average current
can be drawn during the step operation.

*The Output current for DC is 50% of rated current.
The piezo element is capacitive so that as shown
in Fig. 1, the output power (current) is required
only on driving (when the voltage changes). While
the piezo element is in static state (when the
voltage is constant), no output power is required.
This power supply is so designed to incorporate
such characteristics.
The output waveform of this product is as shown
in Fig. 2. The ability to extract a peak current
three times the rated output current can increase
the response of the piezo device, enabling faster
operation.
If the average current IAVE is used beyond the
rated output current Imean, the output is stopped.

Connect to the power outlet with the ground using the supplied AC input cord or a power cable
suitable for areas to be used.
The outlet for which the supplied AC input cord or a power cable suitable for areas to be used
should be placed near the product so that can be easily disconnected from it.
Before connecting wires, be sure to cut off the AC input cord. After the work is complete, confirm
that all wiring is correct and that there are no loose connections before turning on the AC input
power.
Hazardous voltage is generated at the output terminals and the load. In order to prevent electric
shock, do not allow to touch the load and connections.
3-4 Protections
a.Power failure protection
There is a circuit installed that makes power supply not to output after recovery from power failure.
The high voltage is not yet output after recovery from power failure.
To rest, the OUTPUT ON/OFF switch needs to be turned OFF and ON.
b.Overvoltage protection (OVP)
With the overvoltage protection, the unit limits the output voltage not to exceed the set value in case
the output voltage exceeds the maximum rated voltage, protecting the unit and load.
c. Overcurrent protection (OCP)
With the overcurrent protection, the unit cuts off the output of all channels when the averaged output
current of a channel exceeds the maximum rated current. At the same time, the yellow indicator of
the OUTPUT ON/OFF switch turns off.
To rest, turn OFF the POWER ON/OFF switch once and then, turn it ON again.

4 Optional Features
8PZJ series
Matsusada Precision
4-1 Output voltage monitor (-L2)

4-3 External sensor input (-LVs)
Turn ON the External sensor select switch.
Inputting the external displacement sensor signal enables the closed loop operation.
The input signal should be set to 0 to 10 V (10Vmax at maximum displacement) in advance.
Displacement in accordance with Vcon input voltage can be obtained by inputting 0 to 10V from Vcon-in
terminal.
* Check the maximum input voltage and maximum displacement of the piezoelectric element to be used.
4-4 Overload protection by drooping (-LC)
While the standard model is designed to cut off the output whenever the output voltage reaches 105% of
its rated maximum voltage, this option limits the current and decreases voltage automatically when
reaches 105% of its rated maximum.
As the overcurrent state is canceled, the output voltage will be resumed from the drooping state.
4-5 Cancel the power failure protection (-LN)
This function cancels the power failure protection. This will enable the output ON/OFF by AC input
ON/OFF.
(If the output is ON at the time of power failure, the output will be turned ON by restoring the power. On
the other hand, if the output is OFF at the time of power failure, the output will be turned OFF by
restoring the power.)
