Multi-Switch improves electrical supply continuity. The principle of operation guarantees a higher reliability level than that achieved using a single UPS (on-line with automatic bypass) or several UPS in parallel.
PRINCIPLE OF OPERATION
The Multi-Switch provides electrical distribution and remote management for up to eight network users, powered from either one or two direct mains supplies or UPS or a combination of both.
Multi-Switch can connect each user (up to eight, each with a maximum power demand not greater than 3A), to either of the two power sources (A and B). Load demand is shown on the LCD. See “principle of operation” diagram.
PROTECTION AGAINST POWER SUPPLY FAILURES
If one of the two power sources fails or falls outside specification, Multi-Switch will transfer the connected loads to the second power source (switching is instantaneous even if the two sources are in phase).
PROTECTION AGAINST FAULTS WITH THE LOAD
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.

Available in 16, 32 and 64 A, with a nominal voltage of 230 V, CROSS Rack exists in both single-phase input and single-phase output models. All models are designed for installation in 19” closed standard rack cabinets, occupying 2U in vertical rack space with a protection degree is IP21.
In addition to the protection offered by Chloride UPS units, CROSS Rack ensures a further level of safety, having the ability to switch between alternative power sources. The advanced control Break Before Make (BBM) switching feature, provides high safety for all loads in all operational modes and its reduced dimensions make it ideal for mission critical environments where footprint is a key issue.

Available in 160 - 1250 A, CROSS Cabinet exists with three-phase input and three-phase output models with three or four poles. CROSS Cabinet ensures redundant power to critical through its ability to switch between two independent alternative power sources.
The advanced control logic of CROSS Cabinet provides the highest safety for the load, through a 'break before make' switching, available for any UPS operational mode and any kind of load.
The possibility of integrating the CROSS Cabinet with customers' Power Distribution Units (PDU) eliminates the need for switches. CROSS Cabinet is provided with inputs for the external switching devices’ auxiliary contacts. An LCD display visualises over 50 of CROSS Cabinet’s operating parameters. The messages can be accessed by pushbuttons and the text is available in six languages.
