Should one source fail, the other automatically powers the load. The sources can be two separate AC sources including mains power and UPS, or a combination of the two. PRINCIPLE OF OPERATION The Multi-SWITCH provides electrical distribution and remote management for up to eight network users, powered from two direct mains supplies or UPS or a combination of both. The Multi-SWITCH can connect each user (up to eight, each with a maximum power demand not greater than 4A), to either of the two power sources (1 and 2). Load demand is shown on the LCD. See “principle of operation” diagram. PROTECTION AGAINST POWER SUPPLY FAILURES If one of the two power source fails or falls outside specification, MultiSWITCH will transfer the connected loads to the second power source (switching is instantaneous even if the two sources are not in phase). PROTECTION AGAINST LOAD FAULTS If a fault occurs with one of the loads (for example due to a short-circuit or overload), Multi-SWITCH will disconnect the load to prevent disruption to the others. Multi-SWITCH protects sensitive installations from both power and hardware faults.
