Features:
1.High intelligence and reliable power supply:
It 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 filter considerably increase the immunity of the load to mains disturbances and surges.
The CNG310 series UPS uses on-line double conversion technology (VFI) with an isolation transformer on the inverter output.
It 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 routine to be extended up to several hours.
2.Minimum impact on supplies easy sources:
Input current distortion <4% for the CNG310 with a 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 enables 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 sources isolation transformers and generators over less sophisticated power systems.
3.Maximum battery care:
Battery deep discharge protection;
Temperature compensating charger;
Built-in automatic and manual battery test feature.
4.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).
5.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 to occur.
• Maximum reliability and availability:
Connect up to 6 units in parallel or N+1 redundancy, even of different power ratings. The UPS continues to work in parallel even if one of the interconnecting communication cables is disconnected (CLOSED 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.
• Advanced communication:
Compatible with TeleNetGuard for remote maintenance;
Advanced, multi-platform communication for all operating 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 desynchronization 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 at any time to suit power requirements without influencing the initial investment.

FAQ：
What is low frequency online UPS?
Low frequency UPS is designed on the basis of traditional analog circuit, composed of thyristor (SCR) rectifier, IGBT inverter, bypass and power frequency step-up isolation transformer. Because of its rectifier and transformer working frequency are 50Hz, so called low frequency UPS.
How to divide low frequency UPS and high frequency UPS?
1. High-frequency UPS: Using high-frequency switching technology to replace the UPS power supply of the power frequency transformer in the rectifier and inverter with high-frequency switching components, commonly known as high-frequency UPS, high-frequency UPS is small in size and high in efficiency.
2. Low frequency UPS: UPS power supply using low frequency transformer as rectifier and inverter components that is commonly called low frequency UPS. The main power components features are stable and reliable , strong overload capacity,anti-impact ,anti-interference ability, and strong load capacity.
3. The high frequency UPS power supply does not have an isolation transformer, and its output zero line has high-frequency current, mainly from harmonic interference of the mains grid, UPS rectifier, high-frequency inverter ripple current and harmonic interference of the load, etc., and its interference voltage value is not only high and difficult to eliminate.
The output of the low frequency UPS power supply has a lower zero ground voltage, and there is no high frequency component, which is more important for the communication security of the computer network.
4. The high frequency UPS power supply is small in size, light in weight, low in price, that is suitable for small power equipment protection at a single working point.High frequency UPS is insensitive to interference-insensitive equipment and reliability.
The low frequency UPS is suitable for all equipment protection. Whether it is a network point equipment or an IDC (data center), the reliability is high.But the low frequency UPS has the disadvantages of large volume, heavy weight and high price.
5. The high frequency UPS power supply adopts IGBT rectification and inverter, and does not need the output transformer to boost, so there is no output isolation transformer. the volume is also relatively small and suitable for low-power power supply.
The low frequency UPS power supply adopts thyristor rectification. After the inverter, it needs to be boosted by the transformer to supply power normally. Therefore, there is an output isolation transformer, the transformer volume is also relatively large, which is suitable for high power supply.
