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

Dynapower’s digital control upgrades are a cost-effective means of improving the performance and extending the operating lifetime of high power rectifiers. High power rectifier control platforms are designed with specialized electronics that can become obsolete relatively quickly, while rectifier transformers can last decades. Digital control upgrades offer an alternative to complete rectifier replacement to improve the efficiency of many operations. Dynapower engineers typically 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.

BENEFITS OF CONTROLS UPGRADES:

+ 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 hands-on, on-site training for end users. Your staff will learn how to operate and maintain equipment, troubleshoot problems, and extend the lifetime of the equipment to maximize efficiency and reduce costs. The upgrade includes a user-friendly and intuitive touch screen operator panel. A complete set of documentation is developed and delivered by Dynapower and our engineering and support services are available before, during, and after the upgrade installation.

TOUCH SCREEN DIGITAL CONTROL

Dynapower’s new HMI and PLC based Controller for high power rectifier systems 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.
