5 instructions for using piezo electrical elements and power supplies


Piezoelectric actuators from piezosystem jena are controlled by voltages up to 150V.
These values can be quite hazardously. Therefore read the installation instructions carefully
and only authorized personal should handle the power supply.

After transportation, piezoelectric actuators should be allowed to adapt for approximately
2 hours to the room temperature before being switched on.

Piezoelectric actuators are made from ceramic materials with and without metallic casings.
The piezo-ceramic is a relatively brittle material. This should be noted when handling
piezoelectrical actuators. All piezo-elements are sensitive to bending or shock forces.

Due to the piezoelectric effect piezo-actuators can generate electrical charges by changing
the mechanical load or the temperature or such actions described above.

Piezoelectric actuators are able to work under high compressive forces. Only actuators with
a pre-load can be used under tensile loads (these tensile forces must be less then the pre-
load, given in the data sheet).

Please note that the acceleration of the ceramic material (e.g., caused by fall down,
discharging or high dynamic application) will occur.

After excitation of the actuators by a voltage in the upper control range, the ceramic will
move and generate an opposite high voltage after disconnection.

Heating of the ceramic material will occur during dynamic operation and is caused by
structure conditional loss processes. This may cause failure if the temperature exceeds
specified values cited below.

With increasing temperature, up to the Curie temperature (usual values approx.
140°C - 250°C), the piezoelectric effect disappears.

Piezoelectric actuators such as stacks or other devices work electrically as a capacitor.
These elements are able to store electrical energy over a long period of time (up to some
days) and the stored energy may be dangerous.
