Dual Channel “Smart” Power Amplifier Uses Mixed-Signal Processing  to Generate Multi-Pulse Waveforms Used in Industrial Ink Jet Printing

Apex Microtechnology is making the design of power analog drive circuitry for industrial ink jet printer nozzles less of a challenge by pairing a high performance power amplifier with a digital front end. The MP113 is a complete solution for implementing multi-pulse waveforms required to drive a changing number of print nozzles with quality and accuracy in large format printing applications. 

The MP113 features onboard firmware that controls a dual channel amplifier that allows the user to define the desired waveform for their specific end system. The amplifier is rated at >10A PEAK per channel with a voltage supply operation of 180V and up to 135V of output voltage. 
“The MP113’s graphical user interface provides a simplified solution that is easy to implement with an existing drive system or an entirely new design,” explains Apex Strategic Marketing Manager Jens Eltze. “The MP113 supports expanded printing capabilities including the use of grayscale and the ability to change droplet sizes for greater intensity which is needed to print higher resolution images.” 

The modular design of the MP113 is in a broader sense its own evaluation kit. The embedded firmware allows users to test various parameters such as the size and speed of droplet formation and to optimize these specifications for specific types of ink. The MP113 also is designed with protection and diagnostic features to enhance the overall reliability of the system.
