Drive Electronics

The JetDrive™ III drive electronics is designed to provide complex drive waveforms to MicroFab’s MJ microdispensing devices. It is computer controlled via serial communications (RS-232) and an external trigger is provided for real-time control during printing operations. An output to drive an LED strobe for drop observations is also provided, including a delay that is controlled either through the computer interface or a knob on the front panel. A Windows® based control program (JetServer™) is provided, along with the command set for customers who want to integrate control of the JetDrive™ III into their own software. An optional LabView® sample program is available. The JetDrive™ III comes in single output and multiple output configurations.

Standard Features

  • Computer controlled; Windows® based control program provided, along with command set.
  • 8 point bipolar trapezoidal waveform plus 12 point arb waveform mode.
  • External trigger for real-time control; LED strobe output / delay.
  • Integrated into VaportJet™, SphereJet™, Jetlab® II, and the Jetlab® 4 family.

Available Options

  • USB relay unit for multiplexing of a single channel output.
  • Multichannel units for simultaneous drive. Configurations for up to 4 and up to 16 output channels.
  • LabView® sample program.
