hPa are available under the order number P-843.x0V.
All specifications based on room temperature (22 °C ±3 °C).
Specifications for vacuum versions can differ.
12.2 Maximum Ratings
P-843 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 value corresponds to one third of the resonant frequency of the unloaded piezo
actuator. For further restrictions, see
"Overview of Limiting Factors" (p. 18) .
■ 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 100 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. 18) .
■
Maximum power consumption:
The value corresponds to the power consumption of the unloaded, uncooled piezo
actuator that is operated at a voltage of 100 V peak-to-peak with the operating frequency
from column B of this table.
