The mechanical structure of Multi Guard Industrial makes it particularly versatile for
use in many different sectors.
The basic building blocks are 20 kVA UPS. The cabinet is able to house up to four 20 kVA modules and up to two cabinets can be connected in parallel for a total of eight UPS modules and 160 kVA of power. The module connection clamps are laid out so that the communication signal connections are segregated and separated from the power connections (input, output, by‑pass line, battery), thus ensuring complete immunity from interference
generated by the power supply grid, which is typically disturbed in industrial environments.
Both versions (single-phase and threephase output) are provided with a by‑pass line separated from the power supply line. This ensures greater availability in that the customer may have a preferential line for the by‑pass that is not restricted by the potential interference or interruptions that the UPS power supply line may be subject to.
The UPS module has a front to back air flow, allowing the UPS to be installed in any environment and preventing the types of ingress problems associated with topvented circulations cabinets.
Every UPS module in the Multi Guard Industrial range can be equipped with a parallel board, a relay board with eight programmable outputs and three inputs (one of which is programmable), and two slots for housing communications interface boards from the MultiCOM range, making the UPS compatible with the various types of protocols and supervision systems typical of the industrial environment. The cabinet is designed to house up to four UPS modules. I t has an area that contains all the protection devices and disconnectors for the individual modules (4 input disconnectors, 4 battery disconnectors, 4 bypass line disconnectors and 4 output disconnectors), as well as a manual bypass for isolating the four modules and guaranteeing power continuity in the event of the complete failure of all the UPS units or in the event of scheduled system overhaul.
The cabinet is also equipped with an area that can be used for the insertion of a whole range of accessories for monitoring power that the user can request (surge arresters, energy meters, earth discharge detectors, output distribution, release coils, etc), making the solution compact and optimised for any field of use.
