Piezos
STACK
0 to 120 V for
FREQUENCY
(default)
0 to 150 V optional
DISC
100 ± 16 . 4 V feedback
Scan rate
4 to 70 Hz
Note The default maximum piezo voltage is 120 V but can be increased
to 150 V by a simple resistor change. Contact
MOG
labs for further
information.
Note The maximum piezo drive current is 10 mA, which limits the scan
rates for piezos with high capacitance. For exmaple, for a 250 nF
piezo, the rate should not be greater than 25 Hz.
