NOTE! DANGER!
Directly measure the PZT OUTPUT end or both ends of the accessory cable
with an instrument such as an oscilloscope. When the output voltage exceeds 300V, pay attention
to the measurement voltage range of the oscilloscope and other instruments, otherwise it will
damage your measuring instrument!

4.7 E Combined Power Amplifier Module
DANGER!
The combined power amplifier module E07 can output high voltages up to 1800V. The
combined power amplifier module E05 can output high voltages up to 800V. Touching this high
voltage can cause serious or even fatal injuries. Only qualified technicians can install, operate,
maintain and clean the combined power amplifier module!
The combined power amplifier module is based on the principle of high voltage operational
amplifier, which realizes power amplification (voltage and current) of the input DC signal or
AC signal or random signal, and outputs the amplified signal at the output port to drive the
piezoelectric ceramic (PZT). The output of the combined power amplifier module depends on the
input signal, and the magnitude and waveform of the output voltage is equal to the input signal
multiplied by the amplification factor.
