Multi Guard Industrial is a modular solution developed to ensure quality continuous power in industrial settings or similarly harsh environments. Available as a standalone 20 kVA model or as a modular solution offering up to 160 kVA in a single system.

Flexible solution delivers near unity power and is available in both 1-phase and 3-phase output configurations. Multi Guard accepts both single-phase and three-phase inputs without the need for special setup. Parallel 2 cabinets for 160 kVA of power.

High adaptability to input voltage 
Multi Guard Industrial is available in two versions: single-phase and three-phase output, whilst the input stage accepts both a triplet of three-phase supplies out-of-phase by 120° (three-phase 400 V+N) or a triplet of power supplies in phase (single-phase 230 V+N). Thanks to its power supply recognition function the UPS is able to adapt to the input power supply with no need for additional configuration, ensuring the same performance under both applied voltage conditions.

Zero impact source 
Thanks to the technology it employs, Multi Guard Industrial solves all problems connected with insertion into power supply grids with limited power, where the UPS is supplied by a generator and where the same network includes single-phase (e.g. railway voltage) and three-phase (e.g. emergency power supply from a generator) supplies.
Multi Guard Industrial has zero impact on the power supply source, whether it is a mains grid or generator set, single-phase or three-phase:

  • Power supply voltage recognition (single/ three-phase), with no need for setting up or reconfiguring parameters;
  • Input current distortion <3%;
  • Input power factor 0.99;
  • Power walk-in function that ensures progressive rectifier start up;
  • Start up delay function, to restart the rectifiers when mains power is restored if there are several UPS in the system;
  • ‘Cold start’ function for starting the UPS from the battery.

Compatible with industrial environments 
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.

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. It 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.

Modular Plug & Play solution 
Multi Guard Industrial can be purchased as a single 20 kVA UPS module and installed in any cabinet or mechanical support provided by the user. The power terminals (input, output, battery) are connected by harting connectors, ensuring simplicity and operating safety during insertion/removal, protection against electrical contacts and immunity from environmental conditions typical of industrial environments (dust, humidity, suspended chemical particles). The removal and replacement of a faulty module or the addition into the system of a further UPS module to increase available power or redundancy can be carried out easily by the operator responsible for the system.

Complete flexibility 
Multi Guard Industrial is the ideal solution for industrial environments in which the UPS must adapt to the various requirements typical of this application.
Aside from the distinction between single-phase and three-phase output voltages, the UPS module can be used as a standalone unit or in a parallel configuration; by simply adding the parallel configuration board in the slot on the front of the module, the UPS can grow as requirements demand (from 20 to 160 kVA).

Standalone version 
Different from the cabinet version, the standalone system is supplied with input, bypass line, output and battery connectors with loose cables three metres in length and filter boards that the installation technician must position inside the destination cabinet or near the module.
