ATS 3 PHASE UVR, ABB CONTACTORS 55-1600A-160A-230Vac L-N / 400Vac L-L

The ATS UVR is our economy range of ATS (Automatic Transfer Switch) panels. It offers all of the control and monitoring functionality, associated with an ATS panel, with out the need of a control module.  A phase failure relay is used for Mains (Utility) voltage monitoring and offers Under and Over voltage protection as well as phase sequence.  The panel uses two timer relays to control timing functions for the panel.   Timer 1 is used to control the Mains restoration period, this controls the period the Mains supply has to be healthy before engaging the Mains contactor. Timer 2 controls the generator settling period, this time period ensures the generator has ran up to speed and stabilised before a load is applied to the generator.
