THREE-PHASE IN / THREE-PHASE OUT
DOUBLE CONVERSION ON-LINE

QUALITY POWER SUPPLY 

EPI X4 is an On-Line double conversion (VFI) UPS with filtered and stabilized sinusoidal output voltage. X4 is immune to the interferences on the electric power supply line as it has special input and output filters.

MAXIMUM RELIABILITY AND POWER AVAILABILITY 

The digital control of the appliance considerably improves reliability, since a reduction in electronic components lowers the likelihood of breakdowns. Digital control is provided by the microprocessor that, in the X4 series, controls all the internal parameters, thus increasing reliability and performance. In parallel connections, digital control ensures balance of the currents, which generally change over time due to phenomena such as vibrations and temperature, between the UPS units and the exchange of information with no need for manual tuning. 
X4 has been designed so that it can be connected inparallel even after the installation of the first unit.The power availability can be increased thanks to various configurations available such as the parallel configuration, the Dual Bus function and the Dynamic Dual Bus system.

HIGH EFFICIENCY
If required, the unit can work in ECO mode to increase efficiency up to 98% and consequently reduce energy dissipation and costs. In this operating mode the mains is the priority source and the load is switched over to the Inverter only when the mains characteristics exceed the preset limits.

UPS FOR INDUSTRIAL LOADS

X4  with  its  strong  overload  capability,  outputgalvanic isolation and low harmonic current distortion, is the ideal solution for industrial applications.

Thanks to the high battery current, X4 Series is suitable to work with large battery banks as it can guarantee recharging in 10 hours as recommended by the battery manufacturer.

OPERATING FLEXIBILITY
X4 is an uninterruptible power supply with On-Line double conversion technology that can also operate in Line Interactive mode. All power ratings of the X4 series can also be used as Frequency Converters 50 to 60 Hz and vice versa.

MIMIC PANEL

The mimic panel allows easy and intuitive operation of the UPS. It gives access to the most important parameters: status and alarms, control commands, input, output, battery measurements (power, current, voltage, frequency and temperature) and settings. The X4 diagnostics system includes up to 128 alarms or messages allowing precise and detailed identification of any event.

MAXIMUM BATTERY CARE
Optimal battery management includes:
• Periodic battery test,
• Protection against deep discharge,
• Recharge temperature compensated.

MAXIMUM SAFETY FOR PERSONNEL
The back feed protection device prevents any voltage back feed in the upstream distribution board, thus ensuring the safety of the maintenance personnel.

 FRONT ACCESS
X4 has frontal access for all power and electrnic components, even in those configurations with internal batteries. This reduces the floor space required and consequently reduces the installation costs.

ADVANCED COMMUNICATION
UPSMon software displays the most important information such as the input and output voltage, the load applied, the remaining back-up time, etc., in the form of bar graphs. The software is able to provide information even in the event of a failure, in support of the fault diagnostics. The UPSMon software can be used to program the automatic shutdown of all open systems in the event of a prolonged black out. X4 can also operate with a network agent for applications on LAN or WAN networks.

The UPS contains the following hardware interfaces:
• RS232 serial port,
• Dry contacts,
• EPO (Emergency Power Off) contact for UPS 
shutdown using the remote emergency button.

EXPANDABILITY
The units can be connected in parallel up to 8 units to increase power availability or redundancy. The single module or the system can be expanded any time to suit power requirements without influencing the initial investment.

DUAL BUS SYSTEM
The Dual Bus System powers the priority loads from two independent sources. This configuration increases the redundancy and availability level of a multi-module configuration. Each bus may consist of a single module or up to 8 modules in parallel, kept in synchro by the UGS (UPS Group Synchroniser).

DYNAMIC DUAL BUS SYSTEM

Two independent systems set in Dual Bus Configuration can be merged together at any time for system expansion or maintenance. This provides a lot of flexibility in your installation in case of maintenance or when it is necessary to change the redundancy level of both systems.
