hPa
** From one mechanical hard stop of the runner to the other mechanical hard stop, only in open-loop operation
*** When operated with a digital controller with 25 W peak power output
**** With an optimally decoupled load of 2 kg at max. 70 % duty cycle and external cooling of the digital controller, at 1013 hPa. Highest endurance
within the PiezoWalk® family.
***** With max. 15 % duty cycle, at 10

All specifications based on room temperature (22 °C ±3 °C).
Maximum Ratings
The N-331 is designed for the following operating data:

-20 to 120 V
300 Hz 30 W
Nanostepping 12 mm/s 9 W
Full step 15 mm/s 11 W
1 To ensure stable operation, the maximum operating frequency is defined as approximately
1/3 of the mechanical resonant frequency.
2
The heat generated by the piezo actuator during dynamic operation limits the value for
maximum power consumption.
