10 Technical Data
P-2x5 Piezo Actuator PZ245E Version: 1.1.1 43
10.1.2 Maximum Ratings
P-2x5 piezo actuators are designed for the operating data specified in the table below.
The permissible maximum values apply to operation with a sinusoidal signal. If you want to
operate the piezo actuator with a square wave signal at a high frequency, contact our customer
service department (p. 39).
Additional information on the maximum ratings table

Maximum operating frequency without load, without considering thermal aspects,
column A:
The value corresponds approximately to one third of the resonant frequency of the
unloaded piezo actuator. For further restrictions, see "Overview of Limiting Factors"
(p. 30).

Maximum operating frequency without load, considering thermal aspects, column B:
In order to prevent the maximum permissible operating temperature from being
exceeded, the operating frequency of the unloaded, uncooled piezo actuator must not
exceed the specified frequency when the operating voltage is 1000 V peak-to-peak . In
the case of smaller amplitudes of the operating voltage and/or the use of cooling
measures, higher operating frequencies are possible. For further restrictions, see
"Overview of Limiting Factors" (p. 30).

Maximum power consumption:
The value corresponds to the power consumption of the unloaded, uncooled piezo
actuator that is operated at a voltage of 1000 V peak-to-peak with the operating
frequency from column B of this table.
