Specifications︰ The Modular Fire Pulse Generator is an 8-channel,
high voltage DC pulse generator that provides the
fire pulses needed to actuate piezoelectric elements
in Dimatix printheads and jetting assemblies.
The MFPG controller drives up to 8-channels via
separate power amplifier cards. Each power amplifier
card is a separate fire pulse generator capable of
driving 1024 jets, depending on the drive voltage and
other usage parameters. The power amplifier card
can produce fire pulse amplitudes up to 112 volts at
firing frequencies up to 35 kHz. The fire pulse
amplitude for each channel can be independently
adjusted, while the fire pulse timing for all channels
is driven by a common pixel clock.
Power distribution, serial data programming, signals
display line, housekeeping and fire pulse outputs are
routed through the logic board. Control and status
communication is via a serial COM port using the
identical protocol to the Head Drive Electronics
Module (HDEM) used in the Apollo II Printheads
Support Kit.
The MFPG controller is a compact, low cost and
powerful fire pulse generator module that is easily
integrated into a system. The powerful amplifier
drives a fire pulse with no discernable signal
degradation to a printhead or jetting assembly up
to 10 meters or 35 feet away.
