Control Upgrades for Legacy High Power Rectifiers

Upgrading to the Latest Control Systems Improves Plant Reliability, Safety, and Your Bottom Line

Dynapower’s digital control upgrades are a cost and time efficient answer to improving the performance and extending the life-cycle of legacy high power rectifiers. A high power rectifier control platform is designed with specialized electronics that, due to rapid technology advances, can quickly become obsolete whereas rectifier transformers can last decades. Digital control upgrades can be an attractive alternative to rectifier replacement to improve the efficiency of many operations. When it is deemed safe to do so by our team of engineers, Dynapower will recommend a control upgrade when the cost is less than 30% that of a new rectifier. Dynapower offers custom engineering and field service to modernize not only Dynapower and Rapid Power Technologies high power rectifiers, but all other rectifier manufacturers products including PEC, GE, InverPower, ABB, Siemens, Satcon, Robicon, Westinghouse and Neeltran rectifiers.

A Dynapower control upgrade can be completed with minimal downtime and interference with production.

KEY BENEFITS:

+ Optimized Rectifier Performance
+ Improved Maintenance Capabilities
+ Long-term Availability of Spare Parts
+ Long-term Availability of Engineering Support


A Dynapower control upgrade includes Dynapower engineer-directed evaluation, design, installation, testing, commissioning, and either hands-on or on-site training for shop floor personnel through management. Your staff will learn how to safely operate and maintain equipment, troubleshoot problems faster, and extend the lifetime of the installation to deepen efficiency and cost savings. The upgrade includes a user-friendly intuitive operator panel accessed through a touch-screen. A complete custom set of documentation is developed and delivered by Dynapower. Our engineering and service support are available before, during, and after installation. 

DIGITAL CONTROL TOUCH SCREEN

Dynapower Company is proud to introduce its new HMI and PLC based Controller for our SCR and Switchmode rectifier systems. This new device includes all of the features found in our touch pad controller such as system status monitoring, cycle timing, pulsing, interlocks, plus additional benefits from a flexible software platform which can be customized to your specific application. Remote control can also be easily integrated using analog signals while Ethernet access and other means of communication can be used for connection to a network or multiple rectifiers.
