Thomas & Betts Cyberex® Cyberwave Three-Phase UPS Features Advanced Topology

Design Provides Greater Online System Efficiency and Longer Battery Life

MEMPHIS, Tenn. - The Cyberex® Cyberwave Industrial three-phase uninterruptable power supply (UPS) from Thomas & Betts features advanced topology that separates the rectifier and charger, enabling the inverter to operate at greater efficiency and provide better control of the UPS' output. The inverter also tolerates high overloads because an insulated gate bipolar transistor (IGBT)-based pulse width modulation (PWM) design enables highly efficient and rapid switching. With operation to an ambient temperature of 50 degrees Celsius (122 degrees Fahrenheit) with only a 10 percent power derating, the Cyberex Cyberwave three-phase UPS is particularly suitable to rugged industrial environments.

The Cyberex Cyberwave three-phase UPS' topology also prolongs the service life of the batteries by using advanced charging technology. One of several different battery bus voltages can be specified to enhance application flexibility.

"We developed the three-phase UPS for critical industrial applications," said David Sciandra, sales engineer with Thomas & Betts. "It ensures greater system reliability and security in oil and gas processing, power generation and heavy manufacturing environments."

The system incorporates Cyberex's 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 because it is designed to have no single point of failure.

An online, double conversion system, the Cyberex Cyberwave three-phase UPS is compliant with Underwriters Laboratories (UL1778), offering from 10 to 150 kVA ratings with a 20-year service life.
The system also features parallel redundancy and rugged downstream overload and fault-clearing capabilities.

The system's diagnostics provide the operator with status and alarm information via a user interface that includes an eight-inch-by-six-inch full-color touch screen and an interactive event log that can be downloaded through a universal serial bus (USB) port.

"A continual update is displayed to mimic the system power flow," Sciandra said. "Major components, such as the rectifier, charger, inverter or static switch, are monitored so that operational status will be highlighted in the mimic display. An event log is included, which will store up to 2,500 records of events and alarms."

The Cyberex Cyberwave three-phase UPS' rectifier offers enhanced efficiency and an input power factor at near unity. The included PWM inverter and special output transformer provide low output voltage and low current total harmonic distortion (THD). The system's reliability is enhanced through the application of digital signal processing (DSP) controls and fiber-optic data paths in the controls communication system.
