PZ266E
P-88x.x5 Piezo Actuator
Operating temperature range: -40 to 150 °C.
The operating temperature range does
not
apply to dynamic operation. If your application
involves dynamic operation, contact our customer service department (p. 37).
10.1.2
Maximum Ratings
P-88x.x5 piezo actuators are designed for the operating data specified in the table below.
Additional information on the maximum ratings table
Maximum operating frequency without load, without considering thermal aspects,
column A:
The values apply to unilaterally clamped piezo actuators and are calculated as follows:
A third of the resonant frequency of the unloaded piezo actuator (operation when not
clamped on both sides) divided by two.
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
140 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.
Maximum power consumption:
Power consumption of the unloaded, uncooled piezo actuator that is operated at a
voltage of
140 V peak-to-peak
with the operating frequency from column B of this
table.
