The Cyberex PowerBuilt industrial uninterruptible power supply (UPS) from ABB incorporates proprietary amplitude detection control capabilities, resulting in faster, more accurate fault sensing for system reliability and critical load protection in industrial settings. The company says the system's phase-locked loops (PLL) measure faults instantly and accurately for better load protection.
The new online double-conversion industrial UPS is designed to answer continuing demand from applications including downstream refining and petrochemical processing, upstream oil and gas processing, power generation -- as well as the growing regulatory and safety needs of today’s industrial complexes.
“The conventional zero-crossing methods used for fault detection require multiple measuring periods that must be computed over phase noise,” explains Hans Pfitzer, vice president of engineering at ABB, DMPC Power Protection. “The PowerBuilt Series’ UPS phase-locked loops control system is a proprietary correlation method that enables precise measurements of an input/output waveform, resulting in shorter measurement periods and rapid reaction to protect the critical load during a power quality event.”

The threat of lost production or the possibility of damage to work in process is a central manufacturing concern, notes ABB. Therefore, the Cyberex PowerBuilt industrial UPS relies an insulated gate bipolar transistor (IGBT)-based pulse-width modulation (PWM) inverter design that employs active current limitation for higher short circuit tolerance. The active short-circuit method ensures the best possible current clearing waveform, says the company, while still protecting the inverter from catastrophic failure.
In the event of a load side short circuit or over-current that cannot be supplied by the inverter, the UPS logic will transfer away from the active inverter source, thereby preventing the fault condition from damaging the inverter. The newly developed intelligent control logic internal to the Cyberex PowerBuilt industrial UPS acts as a "silent sentry" that continuously safeguards the system to ensure uninterrupted operation. Further, the Cyberex PowerBuilt Series UPS is designed to UL 1778 safety and IEC 62040-3 performance standards, and therefore can be scaled to meet changing electrical requirements, and is adaptable to the most stringent technical specifications.
Finally, the new industrial UPS's user interface with full-color touch screen graphical user interface (GUI) enables self-guided serviceability with minimal engagement, as well as the latest communication protocols, says ABB. The unit also features a patented digital static transfer switch design, which enhances system performance through increased redundancy and reliability. The fully rated switch provides better protection of critical loads from input power transients and interruptions by eliminating any single point of failure, claims the company.
