Automatic Transfer Switch Plug & Play installation HIGHLIGHTS • Redundant power supply • Load protection • Versatile to use Riello UPS Multi Switch ATS is a high availability intelligent switch that provides redundant power to connected equipment with two AC input sources. Multi Switch ATS supplies power to the connected loads from a primary mains source. If that primary source becomes unavailable, Multi Switch ATS automatically transfers loads to the secondary source. The transfer from one source to the other is performed according to the ITIC (CBEMA) times chart and so it does not impact the operation of the connected equipment. Multi Switch ATS monitors the current and provides warnings when power consumption draws near the maximum rating which helps prevent downtime to the equipment. Multi Switch ATS 16 A has 8 IEC 10 A and 1 IEC 16 A outputs, whilst Multi Switch ATS 30 A has 4 IEC 10 A, 1 IEC 16 A outputs and a terminal board allowing several devices to be plugged directly into the ATS without the need for an additional PDU. The units have a connectivity slot which allows for LAN connection and remote management through PowerShield3 software, Web interface, SNMP, or SSH which makes the Multi Switch ATS an ideal device for the IT manager who needs flexibility and protection on their IT equipment. Multi Switch ATS provides installations with power supply continuity. Its operating principle ensures higher reliability than a single UPS, (with or without its own internal bypass). OPERATING PRINCIPLE Multi Switch ATS provides direct distribution of eight 10 A IEC outputs or one 16 A IEC output in the 16 A model, four 10 A IEC outputs one 16 A IEC output or a terminal board in the 30 A model in a system with two input power lines (two mains inputs, or two UPS). Multi Switch ATS is able to connect to either of the two input power lines, whilst simultaneously monitoring the power uptake. PROTECTION AGAINST LOAD FAULTS If one of the loads fails (e.g. short circuit), the Multi Switch ATS disconnects the group of sockets where the load is connected, thus preventing other loads from being switched off (i.e. in the event of poor discrimination of the protection device

PROTECTION AGAINST POWER SUPPLY FAULTS If one of the two power sources falls outside tolerance levels, Multi Switch ATS will transfer the load to the second power source (switching is instantaneous if the two sources are in phase). Multi Switch ATS units switch power with no impact to IT equipment. Depending on the ITIC curve, typical power supplies will operate 20 ms after AC voltage drops to zero. The IEEE 1100-1999 standard also references the ITIC curve. The SSI (Server System Infrastructure) standard recommends a hold-up time for power supplies to be a minimum of 21 ms for a voltage range...
