The efficiency of the whole UPS systemexceeds 93%.
Human-Machine InterfaceThe 7-inch color touch screen can provide text and mimic diagrams display at the sametime, which is suitable for users to view status, data and operation control. The internalCPU can record historical events and alarm information, and the information storagecapacity is up to 10,000.
The display content includes: input voltage, input frequency, output voltage, output current,output frequency, active power, apparent power, load rate, float charge voltage, equalizingcharge voltage, charging current, charger temperature, battery voltage, battery packtemperature, remaining battery discharge time, percentage of remaining battery capacity.battery status, historical records, etc.
IntelligentAdvanced digital calibration function, the voltage and current can be calibrated by softwarewithout any adjustable resistance.
Self-diagnostic technology, real time monitor the working status of inverter, rectifier andother circuits, detect battery capacity and status, detect UPS working ambient temperature,and detect the failure of each fan to avoid UPS failure.
Low Power Consumption and High EfficiencySupport ECO economic mode operation. When ECO fault,it will transfer to inverterautomatically. Allow users to select Online / ECO /Bypass operation modes. In the ECO economic mode, the UPS operating efficiency can be up to more than 98%, which caneffectively reduce the UPS system power consumption. And it's the first choice for low-carbon times.
Advance Battery ManagementAdopt intelligent advance battery management (ABM) technology to reduce batterymaintenance times. The advanced constant current and constant voltage automaticconversion charging technology can activate the battery maximally and save charging time.
The battery management system has functions, such as battery capacity prediction,discharge time estimation, and low-voltage warming. Moreover, it can perform self-diagnosisand self-checking for the battery pack, with charging voltage temperature compensation,intelligent adjustment of battery discharge termination voltage, automatic battery dischargeactivation at regular intervals, automatic setting battery charging current and other functions(this part of the function requires separate configuration components, non-standard), supportlithium-ion batteries (requires separate configuration components, non-standard).
Predictive Alarm SystemThe LCD panel has automatic detection function, timely forecast and alarm in advance, and self-diagnosis function when UPS initial start-up, which can avoid the risk of failure and personalsafety that may be caused by UPS hidden dangers in time.
Support automatic and manual battery online test functions. Users can set different test cyclessuch as day, week, and month to perform automatic battery test, provide sound and light alarms,and display corresponding information on the LCD display to discover potential battery failures in time.
Powerful Parallel Redundant / Parallel Capacity FunctionDSP full digital control technology in the core system, ET-LV series online UPS has not only N+1 or N+X parallel redundancy, but also increases total power capacity, it can be simultaneouslyparallel within 8 units, which greatly reduces the user's up-front purchasing costs and subsequent growth costs.
Superior Environmental AdaptabilityThere is superior environmental adaptability for ET-LV series Online UPS, and a wide AC input voltage range, thereby reducing battery usage frequency to extend its service life.
Wide AC input frequency range is suitable for connecting various fuel generators.
Three phase output allows 100% unbalanced for 3 phase loads.
Great load adaptability supports RCD non-inear load, industrial grade impact load, motor load, etc.
All circuit boards adopt three-anti-coating technology, that is, dust-proof, anti-humidity, and sall-proof. The UPS can be used in harsh environments, and extend UPS service life.
True Online Double Conversion TechnologyTrue online double conversion technology makes the UPS pure sine output with frequencytracking, phase locking, voltage stabilization, and noise filtering, which is not interfered byelectrical grid fluctuations. Output zero transfer time enables UPS to provide more comprehensiveprotection for users'precision equipment.
ET-LV UPS is built-in isolation transformer, static bypass switch and manual maintenance bypass switch.
Multiple Communication InterfacesThere are a variety of communication interfaces to monitor the UPS operation status, like RS232,RS485,USB, CAN, NET, Input/Output dry contact, SNMP card, WIFI card, GPRS card and 4G card, etc.
Through external connecting "Prostar IOT" smart dloud box (optional), computer monitoring andmobile APP(including IOS and Android) monitoring can be performed, with remote networkmanagement functions. It can also send alarm information via Wechat or mobile text messages toprovide reaktime UPS data and power information.
Battery Cold StartIn the abnormal state of the utility power, the UPS with a battery cold start switch can be starteddirectly with the battery to meet emergency needs. When the battery is discharged to EOD, UPSonly start automatically while the utility is restored, and it has an unattended function.
Integrating lsolation TransformerET-LV series UPS is equipped with an isolation transformer, fully integrated to the UPS unit depending on the customer's galvanic isolation need (output andinput). Integrating the transformer directly to the UPS saves footprint and provides all the benefits of galvanic isolation including a very robust buffer betweenthe utility and the critical load.
Comprehensive ProtectionThe UPS provides perfect software and hardware protection, as well as fan failure alarm. It also provides various protections, like AC input overvoltage/under-voltageprotection, AC output overvoltage/under-voltage protection, overload, short-circuit protection, over-temperature protection for inverter and rectifier, battery under-voltagewarning and under-voltage protection, battery over-charge protection and other protections to ensure the UPS system operation stability and reliability. Powerful overloadability, it can maintain 60 minutes / 10 minutes / 1 minute under 110%/125%/ 150% overload.
