Engineers at Zuno Engineering Develop 1000VDC DC to DC Converter

Engineers at Zuno Engineering have successfully developed a 1000VDC to 220VDC 7.1kW DC-DC converter. This design utilizes a phase shifted full bridge topology to accurately and efficiently (~95%) convert the fluctuating (450-1000VDC) input to a clean 220VDC output. This system is also galvanically isolated and has controls for power enable and voltage and current feedback allowing the system to operate as part of a larger power converter system. Zuno will soon be developing the production ready PCB from the prototype in the photo displayed.

Zuno Engineering Completes Rockwell Automation Motion Control Course

Zuno Engineering has completed another training course from Rockwell Automation in Indianapolis, IN covering motion control using servo drives and Variable Frequency Drives (VFDs). The completion of this course allows the engineers at Zuno to deploy and maintain motion control solutions quickly to our customers. Zuno is slated to be certified in Rockwell Automation programming mid July 2015.

Zuno now offering Thermal Imaging Service and Analysis

Zuno Engineering now has access to thermal imaging equipment so that we can provide thermal analysis of electronic cooling issues on high power PCB applications. Below is an image of a high power lighting design, you can see that the FET and current sense resistor is much hotter than the rest of the circuit at it is conducting the most power, however it is still well within temperature specs for the parts. This type of analysis will allow for Zuno Engineers to accurately troubleshoot, diagnose and fix thermal issues in PCB designs.

Zuno Engineering is now a Rockwell Automation System Integrator

Zuno Engineering is now a System Integrator for Rockwell Automation. This allows us access to all of the development tools from Rockwell Automation as well as training and technical support directly from Rockwell Automation. Becoming a System Integrator allows us to help our customers solve production issues quickly with minimal risk.

From the Rockwell Automation website (

"In an increasingly competitive global marketplace, leveraging technology to help sustain profitable business growth is a focus for many companies. Our System Integrator program is designed to educate and produce qualified partners who are able to help solve production challenges by advising on and delivering the best solution with the lowest amount of risk.

The program offers system integrators around the world the chance to continually enhance competencies and capabilties across mutiple disciplines: control, information, process, safety and manufacturing operations. For system integrators who make the commitment to deliver the highest technical solution and customer service, leading with Rockwell Automation technologies, we develop and promote these Recognized System Integrators and Solutions Partners. The Recognized System Integrators are resources who best positioned to reduce project risk when leveraging our technologies. Solution Partners possess those same traits, but they differentiate themselves with a capability that is unique and specialized, with the ability to deliver across a broad geography."

Zuno Engineers receive official training on Rockwell Automation software and Allen Bradley hardware at Kendall Electric

Engineers from Zuno have completed two official courses from Rockwell Automation to work towards becoming Rockwell Automation Certified Programmers. While the engineers at Zuno all hold degrees in Electrical and / or Computer Engineering from ABET accredited universities, specialized training courses from the manufacturer are an invaluable resource.

The courses that were completed are the following:
CCP146 - Studio 5000 Logix Designer Level 1

CCP151 - Studio 5000 Logix Designer Level 2

These engineers will also be taking the following courses to become Rockwell Automation Certified Programmers.
CCP143 - Studio 5000 Logix Designer Level 3

CCN130 - Motion Control Fundamentals

Zuno Engineering now using Mentor Graphics DxDesigner and PADS

Zuno Engineering is now completing schematic capture and performing board layouts in Mentor Graphics DxDesigner and PADS. Many customers that we work with use Mentor Graphics as their internal EDA package, obtaining this license allows us to work with those customers in a more seamless way.

More on Mentor Graphics EDA tools can be found here:

Zuno will still continue to use DipTrace and Eagle on older designs and will support our clients who use these packages. Zuno also still uses LTSpice and MultiSIM for circuit modeling and simulation.
