Gamatronic UPSs will back up motor-driven bollards that SecureUSA (http://www.secureusa.net/) supplies as part of their perimeter defense systems for critical and sensitive installations around the world.
Because the application requires the UPS to feed both 3-phase and single phase motors, Gamatronic’s ability to customize the Power was a critical factor in the customer’s choice. In addition, the Gamatronic unit is the only one that could be configured for the large, single phase motors requiring 45 kVA.
In order to eliminate inrush currents from motor start-up, Siemens VFD’s will be used between the UPS and the motors for the bollards. When tested, the UPSs performed flawlessly and in accordance with all technical specifications.
