We’ve published several articles on the basics of rectifier maintenance and the Preventative Maintenance (PM) packages that we offer. Today, let’s look at one of Dynapower’s recent visits to a manufacturing facility in Texas to see one of our PM programs in action.

Recently, Dynapower’s Repairs Supervisor Remington Schieffer traveled down to Texas with two other team members, Industrial Sales Rep Philip Points and the Regional Texas Service Technician Justin Kohler, to deliver information designed to improve a key client’s process and rectifier uptime.

Rather than simply delivering a cookie cutter presentation, Schieffer and the team collaborated with the client’s chemical providers to incorporate their data into the training. The Dynapower team also threw in a bonus in-depth safety analysis of the client’s manufacturing line in accordance with NFPA 70e and OSHA guidelines.

The training had three main segments. First, the client’s process—and the quality control metrics that drive that process—was discussed in detail. Then, the client’s equipment—which included three different brands of rectifiers—was reviewed at length. The third piece of the training covered spare parts, maintenance cycles and equipment risk and liability.

“During the training we found some areas of improvement for the company and helped coach the customer to more efficient methods of maintenance and safer methods of testing their equipment,” Schieffer said.

Attendees of the training included team members from management, maintenance workers, lab technicians and production supervisors.


 “Management were very satisfied learning more about their process so they could make better decisions on how to reduce scrap and increase first pass yield,” Schieffer said. “And perhaps the biggest impact we made was seeing the confidence that the maintenance team felt after we completed the training.”

Phil Points commented, “I feel that we opened their eyes to the safety and maintenance concerns that need to be addressed in the facility. By focusing on the safety and reliability aspects in their equipment they will be able to optimize uptime and get the most from their efforts.”

During the training, the company’s three types of rectifiers were discussed. These included North American Rectifier, Rapid Power Technologies and Dynapower brand rectifiers. Schieffer said the training focused on component liability, so attendees were able to learn how to perform maintenance across all types of rectifiers rather than being limited by purely brand-specific maintenance.


“The reason our maintenance training is so powerful is because we offer a granular level approach to training,” Schieffer said. “The principles we train can be used across brands and equipment types.”

By focusing on component configurations, trainees came away with a new understanding of rectifier and electrical maintenance. Trainees also learned about universal electrical maintenance principles. In a sense, the training became a form of career enrichment for the attendants.

Diodes can be used in applications outside of rectifiers. “Contactors” or Motor Starters are commonly used in electrical cabinets, cranes, and control panels. By learning how to troubleshoot these devices in the rectifier, you learn how to troubleshoot these devices in all maintenance applications.

“It’s a passion of mine to not give people sales pitch training,” Schieffer said. “This is real information. We care about the success of our clients in the long-term.”

The overall services delivered down in Texas were part of Dynapower’s Preventative Maintenance programs (go here for a full overview of our offerings). In this case, the client had chosen our Bronze package and opted for training at their facility as an add on.
