The inverter drive circuit converts a DC voltage input into
an oscillating AC output. The inverter circuit is provided
for driving low voltage (up to 56 Vp-p), low frequency
( 75 Hz - 400 Hz) resonant piezo devices such as fans,
choppers,and vibrators. The output frequency is adjusted
manually by turning the trimmer pot on the PCB.
Optimum tuning is accomplished by visual observation of
the device motion or inspection of the output waveform
on an oscilloscope during operation.

INVERTER SPECIFICATIONS
12VDC Piezo Fan: The 12 VDC fan (see page 24) can be
bolted directly to the EIN-406. Two wires from terminal
“A” connect to the two solder dots on the piezo fan, and
the metal spacer bolts directly to terminal “B”.
Piezo Resonant Element: The resonant blade element (see
page 25) may be driven using the EIN-406.
Piezo Chopper. The piezo chopper (see page 26) may be
driven using the EIN-405.
Piezo Benders: Bending elements (see pages 32 - 37) may
be driven at resonance using the appropriate inverter
Circuit.
