Detailed

Features：
■ Advanced working mode
· Double Conversion on-line design, which makes the output a pure sine wave source with tracking frequency , phase-lock and voltage regulation, noise suppression, and without power fluctuation interference, providing the load with more comprehensive protection.
· Zero transfer time of output, satisfy high standard power requirements of precision equipment.
· Input power factor is 1.0 with the filter，which improves the energy efficiency, reduces the harmonic pollution of the power grid and lowers the UPS running cost.
 
■ Full DSP Control
· The digital control brings the excellent performance, avoids the risks because of analog devices failure and makes the control system more stable and reliable.
 
■ High output power factor
· The output power factor can reach 0.9（lagging），which has a higher actual load capacity, saving the user’s investment.
 
■ Strong environmental adaptability
· The range of AC input voltage is (380Va/ 400Vac/415Vac)±25%，thereby reducing the battery using frequency and greatly extending the battery life.
· Wide input frequency range from 45Hz～65Hz，ensure all types of fuel generators connected work stable.
 
■ Optimization of high-performance battery
· Adapt intelligent battery management( ABM）technology，thus extending battery life and reducing battery maintenance times.
· Advanced floating switching and charging technology maximums the activation of the battery, thus saves the charging time and extends the battery life.
· Battery discharge time prediction； When battery discharging，the system detects the discharge current and predicts the discharge time according to the battery intelligent management，thus informs the users to do the appropriate measures.
· The battery self-test on a regular basis to detect battery problems in time，Set the start time and self-test duration according to the different time periods (monthly or weekly).
· Wide battery voltage range: 320-490Vdc makes the configuration of battery quantity more flexible.
 
■ N+X Parallel redundancy
· Adapt N+X parallel redundant design. Users can configure different redundancy number according to the importance of load.
· Easy to realize the parallel function. The parallel can be achieved just by connecting the parallel cables and doing
the setting on UPS. At most 6 units can be connected in parallel at most.
· Non-fixed Master-Slave relationship：Among the several UPS in parallel，the unit startup first is Master UPS，the others are Slave UPS. The master and slave can be exchanged. If the inverter of one UPS fails, the UPS will automatically cut off the output, then the load will be powered by remained UPS.
 
■ Strong overload capability
· When overload 110%/125%/150% , it can be maintained 60min /10min/1min.
 
■ Compatible with the generator
· Specially designed power walk in function reduces the in-rush current when system starts, thus lowers the requirement of the generator that the parallel system demands.
 
■ LBS synchronization
· The LBS synchronization function supports the two independent power inputs，which improves the reliability of the system.
 
■ Comprehensive and reliable protection
· Self-diagnosis function before start-up，avoid the risks that the failure may lead to.
· The multi-protections such as AC input under/over voltage, overload, short-circuit, over-current, over bus voltage, over-temperature, fan failure, auxiliary power failure, battery under voltage, battery over-charge and so on greatly ensure the system stability and reliability.
· Bypass function. When overload or UPS fails, it can transfer to bypass without interruption to provide AC power to load and provide the alarm information as well.
 
■ EPO function
· An EPO button is embodied in the LCD display panel. Press the EPO button in emergency can shut down the UPS. The EPO button adapts the concave design with a transparent cover, which can avoid misuse.
 
■ User-friendly network management
· Chinese/English（optional）LCD accurately displays the status of operation and data for users.
· Communication with computer can be realized by RS232 with corresponding monitoring software. The various parameters can be shown on the communication interface.

· External SNMP adapter. The UPS with remote network management capability can provide real-time data for communication and management through a variety of network management systems.
