HIGH INTELLIGENcE AND RELIABLE POWER SUPPLy

mlm/mlT’s capacity of maximum protection for vital mission-critical networks, security applications (electro-medical) and industrial applications thanks to its outstanding mechanical and electrical design. The load is powered continuously by the inverter with a filtered, stabilized and regulated sine wave supply. The input and output emi filters considerably increase the immunity of the load to maintain disturbances and surges. The mlm/mlT uses on-line double conversion technology (VFi) with isolation transformer on the inverter output. The mlm/mlT is supplied with Watch & save 3000 software as standard and can be remotely monitored using the Power net Guard system from anywhere in the world. additional battery extension packs allow the standard battery runtime to be extended up to several hours.

MINIMUM IMPAcT ON SUPPLIERS EASy SOURcE:input current distortion is less than 4% for the mlm/mlT with fil-ter with sinusoidal absorption to remove the risk of resonance with other input supply users or phase shift capacitor sets. The absorbed current distortion is independent of input supply parameters such as impedance. This enable mlm/mlT to deliver maximum perfor-mance levels regardless of the installation environment. With these input features, mlm/mlT can achieve significant savings in terms of sizing and power supply source isolation transformer and genera-tors over less sophisticated power systems.

MAXIMUM BATTERy cARE:l Battery deep discharge protection

l Temperature compensating charger

l Built-in automatic and manual battery test feature.

SIMPLE TO INSTALL:l capability to install the UPs into any distribution system (neu-

tral not required on rectifier input):

l capability to separate the rectifier / bypass power net works and to power these from two separate sources, without Galvan-ic isolation (necessary on UPs without an output transformer).

HIGH RELIABILITy:l extremely high short-circuit current to ensure compatibility

with the most difficult transformer applications (lighting, drives and industrial processes) and an isolation transformer on the inverter output;

l Full microprocessor control with no-break static and manual bypasses;

l iGBT technology

l 0.8 power factor make mlm/mlT suitable for powering

IcT AND INDUSTRIAL LOADS;l high level diagnostics: event log with 128 messages, states,

measurements and alarms-available from the built-in lcD with several languages;

l BacK FeeD Protection: to avoid energy feeding back into the mains supply cause a fault occur.

MAXIMUM RELIABILITy AND AVAILABILITy:connect up to 8 units in parallel or n+1 redundancy, even of dif-ferent power ratings. The UPs continue to work in parallel even if one of the interconnecting communication cables is disconnected (clOseD lOOP)

LOW cONSUMPTION LEVELS:mlm/mlT cab achieve efficiency level less than 98%. Thanks to se-lectable economy mode which can be used in stable electrical en-vironments for providing power supply continuity when the mains fail.

ADVANcE cOMMUNIcATION:l compactible with TelenetGuard for remote maintenance.

l advanced, multi-platform communication for all operation systems and network environments: Watch & save 3000 monitoring and shut-down software included, with snmP agent, for Windows 2008, Vista, 2003, XP; mac Os X, linux, novell and most popular Unix operating systems;

l The UPs is supplied with a cable for direct connection to the Pc (Plug and Play);

l rs 232 double serial port; installation slot for an emergency Power Off (ePO) interface to allow the UPs to be switched off remotely in an emergency;

l Generator interface: enables desynchronisation of the UPs output from a generator supply which may be subject to phase and frequency variations. The interface also enables more economic use of the battery charge.

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 anytime to suit power requirements without influencing the initial investment. Thanks to be peculiarity of the “hot system expansion” feature, the additional unit can be connected in parallel while the other units are on-line and supplying regular power to the load. The new UPs is on-line and will be set up automatically.
