Main parameters


High intelligence and reliable power supply:
CNG310 provides 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 mains disturbances and surges.
 The CNG310 uses on-line double conversion technology (VFI) with isolation transformer on the inverter output.
The CNG310 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 run time to be extended up to several hours.

Minimum impact on suppliers easy source:
 Input current distortion <4% for the CNG310 with filter 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 CNG310 to deliver maximum performance levels regardless of the installation environment. With these input features CNG310 can achieve significant savings in terms of sizing and power supply courcesiso-ation transformers and generators over less sophisticated power systems.

Maximum battery care:
Battery deep discharge protection;
Temperature compensating charger;
Built-in automatic and manual battery test feature.

Simple to install:
Capability to install the UPS into any distribution system(neutral not required on rectifier input);
Capability to separate the rectifier/bypass power networks and to power these from two separate sources, without Galvanic isolation (Necessary on UPS without an output transformer).

High reliability:
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;
Full microprocessor control with no-break static and manual bypasses;
IGBT technology.

Other characteristics:
0.8 power factor make CNG310 suitable for powering ICT and Industrial loads;
High level diagnostics: event log with 128 messages, states,measurements and alarms - available from the built-in LCD with several languages;

Back feed protection: to avoid energy feeding back into the mains supply cause a fault occur.

Maximum reliability and availability:
Connect up to 6 units in parallel or N+1 redundancy, even of different power ratings.The UPS continue to work in parallel even if one of the interconnecting communication cables is disconnected (CLOOSED LOOP).

Low consumption level:
CNG310 can achieve efficiencies >98% thanks to selectable Economy Mode which can be used in stable electrical environments to provide power supply continuity when the mains fail.

Advance communication:
Compatible with TeleNetGuard for remote maintenance;
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;

The UPS is supplied with a cable for direct connection to the PC(Plug and Play):
RS232 double Serial port;Installation slot for an Emergency Power Off (EPO) interface to allow the UPS to be switched off remotely in an emergency;
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.

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.
