ABB Power Conversion announces latest high-efficiency rectifier for manufacturing applications

Reliability and consistency are crucial as the use of industrial lasers in precision manufacturing applications grows. ABB Power Conversion has created the CC7500, a new liquid-cooled, three-phase, 75-volt (V) rectifier, especially for these applications. The rectifier offers the steady, dependable power required for precise production processes and is designed for heavy pulse-load applications like industrial lasers.

The CC7500 is the most recent addition to ABB’s CC-series rectifiers. It has a wide-range 75 V_DC nominal output (65-80 V), redundant +5 V_DC standby power, and a low-line 200/208/240 V_AC input that enables its use in areas with low-line utility power, like Japan. In order to safeguard against potentially harmful components inherent in a manufacturing environment, the fully sealed power supply is IP65-rated. It offers versatile, effective cooling choices for applications in conduction-cooled and liquid-cooled configurations with dripless connectors and versions with integrated heat sinks.

The industry-standard ModBus/RS485 communications interface on the CC7500 rectifier enables it to interact with programmable logic controllers, which are frequently used to regulate manufacturing processes. The rectifier also complies with a number of safety, environmental, and regulatory criteria, such as EN62477-1/IEC61207-1, FCC part 15(A), EN55032 Class A, EN/IEC 61000-3-12, EN60555-2, and EN61000 immunity and transient standards (UL1012). Its small footprint, which is 8.6 inches wide by 2.0 inches high by 19.5 inches deep, enables for both horizontal and vertical arrangement for the least amount of space and the most amount of stacking density. 

Additional key features of the CC7500 industrial rectifier include:

Maurizio Di Paolo Emilio holds a Ph. D. in Physics and is a Telecommunications Engineer. He has worked on various international projects in the field of gravitational waves research, designing a thermal compensation system (TCS) and data acquisition and control systems, and on others about x-ray microbeams in collaboration with Columbia University, high voltage systems and space technologies for communications and motor control with ESA/INFN. TCS has been applied to the Virgo and LIGO experiments, which detected gravitational waves for the first time and earned the Nobel Prize in 2017. Since 2007, he has been a reviewer for scientific publications for academics such as Microelectronics Journal and IEEE journals. Moreover, he has collaborated with different electronic industry companies and several Italian and English blogs and magazines, such as Electronics World, Elektor, Mouser, Automazione Industriale, Electronic Design, All About Circuits, Fare Elettronica, Elettronica Oggi, and PCB Magazine, as a technical writer/editor, specializing in several topics of electronics and technology. From 2015 to 2018, he was the editor-in-chief of Firmware and Elettronica Open Source, which are technical blogs and magazines for the electronics industry. He participated in many conferences as a speaker of keynotes for different topics such as x-ray, space technologies, and power supplies. Maurizio enjoys writing and telling stories about Power Electronics, Wide Bandgap Semiconductors, Automotive, IoT, Embedded, Energy, and Quantum Computing. Maurizio has been an AspenCore content editor since 2019. He is currently editor-in-chief of Power Electronics News and EEWeb and a correspondent for EE Times. He is the host of PowerUP, a podcast about power electronics, and the promoter and organizer of the PowerUP Virtual Conference, a summit where each year great speakers talk about the power electronics design trends. Moreover, he has contributed to a number of technical and scientific articles as well as a couple of Springer books on energy harvesting and data acquisition and control systems.
