nteractive dialogue function
The administrator can be LED, LCD dual display an understanding of UPS current working state, the input voltage, the input frequency, output voltage, output frequency, load capacity, battery voltage, the charging current of the battery, the battery standby time and UPS module working state and alarm information and other information, and can according to the user's actual work situation and external configuration from the panel to undertake a number of set of features andparameter settings, adjust the UPS working mode and technical indicators, extremely strong maneuverability. The full realization of human-computer interactive dialogue function.
Data recording capability
Every abnormal condition occurs in the data and time are saved in UPS, so users can clearly understand the UPSoccurring in any situation, even when there is no power supply condition, stored in the UPS data will not be cleared away.
A unique multiple protection function
With the AC input over / under-voltage protection; output overload, over-current, over-temperature protection short circuit protection; inverter; battery undervoltage warning / protection; battery overcharge protection; wave distortion protection andsystem protection alarm function, thus the machine failure rate is very low, greatly guarantee the system stability and reliability.
All-weather lightning and surge protection
UPS with high energy absorption, rapid response of the surge absorber, absorption from the input power supply surge or lightning wave, protection of the UPS and load safety.
Soft starting function
Is mainly used for preventing on the power system and generator generates a current impact, ( such as: electric powergenerator power supply, battery discharge having electric had returned to produce a startup current, required for the UPS input current soft starting control, to avoid the impact of input end of power, completely eliminating the impact due to thestandby generator device to shut down concerns. )
DC starting function
UPS installation of special current-limiting circuit, even in the absence of electric case, can be directly used for batterystarting with UPS, unattended function, load power required for a period of time is provided by a battery, provides convenience for users, with more extensive, more flexible use.
Intelligent electricity-saving function
For saving energy and prolonging the service life of the equipment, the user can set their own load, setting value is: 0 to 99, when the UPS load falls below a set value, the system is transferred from the bypass state.
The three-phase load unbalanced ability 100%
UPS inverter using digital signal ( third DSP ) control technology, allowing the three-phase load 100% imbalance, which allows any one phase or two-phase load is zero, while the other 100% phase load in three-phase load imbalance, 100%also can normal power supply reliability, load adaptability, high reliability of the system, the output distribution is convenient, especially suitable for computer room, communications and other information system equipment
Optimum generator compatibility
UPS has friendly operation interface, in order to reduce the generator provides power, reduce the capability of the generator, generator start stop UPS to charge the battery; because the key load on power frequency higher, so stop with the generator power supply frequency synchronization. Can withstand the output voltage of the generator and the outputfrequency changes, and effectively remove the negative power generator, is provided for the load of pure, safe, stable power supply.
Cold start, since the launch of the function ( 100% cold load pickup to bypass, strongoverload capacity )
From 0 to 100%, fully able to bear load jump start instant full load impact, but without switching to the bypass, and remained stable and reliable output voltage. When the load is within 125% to 10 minutes, 150% to 1 minutes, more than 150% immediately switch to bypass or shutdown, at any time to meet the load changes come unexpectedly.
" Diagnosis and early warning " function
With a comprehensive self diagnostic function, warning function, the UPS internal fault diagnosis and early warning.
Robust real-time network monitoring and management functions
The intelligent communication interface communication more convenient:
Design through RS-232 digital communication intelligent interface, can be used with any computer and remotecommunication equipment. The UPS parameter stick out a mile display in communication interface realize multipurposecommunications and remote monitoring, check erroneous ideas at the outset, ensure the load device no danger of anything going wrong.
●can choose many kinds of power management software
LAN and WAN comprehensive monitoring and shutdown procedure, the key system to achieve the highest availability.With multiple platform compatibility, LAN and WAN comprehensive intelligent monitoring and power management, the keysystem to achieve the highest availability.
●to SNMP adapter network management system
Connect the SNMP ( Simple Network Management Protocol ) UPS adapter, remote network management function,provide immediate U PS information and power information, through the network management system of communication and management, can make the network management more by this combination, the power management system into the network management system, improve the whole benefit of double.
