Automatic transfer switch ATS010 - R & D

1 Automatictransfer switchATS010 Service continuity to the foreA high level of reliability of thepower supply source is alwaysrequired in the sphere of lowvoltage distribution fact, types of user loadswhere a power cut can causeconsiderable loss of data,damage to work processes,plant stoppages, etc. arebecoming this reason, ABB SACEhas developed ATS010 ( Automatic transfer switch ) -the solution for automaticmains-generator grouptransfer, able to manage thewhole system for emergencypower to a transfer logic withintegrated safety, ATS010offers a highly reliable solutionto the problem of ser vicecontinuity.

2 A high per formancemains sensor, an electricinterlock and the poweroutputs for controlling thecircuit-breakers are allcontained in a single , ATS010 has beenthought up to fit in per fectlywith ABB SACE moulded-caseand air circuit-breakers,thereby ensuring availability ofa complete and - Automatic transfer SwitchDevice for mains-generator group transferATS010 by ABB SACE is amicroprocessor-based electronicdevice dedicated to automatictransfer between a nor mal lineand an emergency line. Inpar ticular, it is able to check thepower supply characteristics ofthe nor mal line and, in the case ofany anomaly, to send the star t /stop commands to the generatorto control the two circuit-breakerswhich have to be apparatus which can becontrolled directly are bothmoulded-case (with store denergy or direct action motoroperator)

3 And air ABB switching ismanaged according to a range ofdelays which can be set by theuser, as well, of course, as anyalar ms coming from the range ofapplicationsThe ATS010 device is highlysuited to use in all emergencypower supply systems where aready-to-install, easy-to-use andreliable solution is of its main applications aretherefore : Power supply of UPS(Uninterrupted Power Supply)groups in general Operating theatres and primar yhospital services Emergency power supplies forcivil buildings, hotels andairpor ts Data banks andtelecommunication systems Power supply of industrial linesfor continuous systemManagement of theCircuit-breakers Possibility of using all theranges of ABB SACE moulded-case and air circuit-breakers Direct connection to the controldevices (motors or coils) formost of the versions availablethanks to the integrated poweroutputs.
