AEC IST7: Online three-phase double conversion UPS
UPS power range
The AEC IST7 UPS series includes double conversion tower UPS with powers from 60kVA up to 200kVA. IST7 UPSs are available in three sizes: 60kVA, from 80kVA to 120kVA and from 160kVA to 200kVA.
UPS Expansion
The IST7 UPS series uses a centralized modular design, allowing for future expansion of the UPS. These UPSs can be expanded in power directly on site and from the display.
The IST7 UPSs offer great flexibility in the number of batteries and high overload capacity, with the innovative self-cleaning function that reduces the risk of dust accumulation on the boards. The system also includes the free contact card for alarms. The batteries are common for parallel systems, with only one battery pack for two N+1 UPSs, and the battery configurations range from 14 to 24 monoblocks (±168~±288Vdc).
UPS characteristics
IST7 UPSs feature ECO mode with efficiency up to 99%, configurable from the display. Furthermore, the IST7 UPSs are equipped with many options and accessories, including the SNMP network card for the control and monitoring of the UPS, the parallel kit, the additional free contact card, the battery cabinets, the of the battery, the N+X configuration in parallel, the isolation transformer and the monitoring on the AEC APP.
The IST7 UPSs have an output power factor of 1 and maximum AC\AC efficiency up to 97%, thanks to the 3 IGBT levels of the inverter. Furthermore, the advanced control with double redundant DSP and the fully tropicalized electronic boards make these UPSs highly reliable.
IST7 UPS features a display available in 7 languages and intelligent fans with high-efficiency cooling, multiple modes to control fan speed, extend life and improve efficiency. The menu is accessible via different password levels (User, Technician and Manufacturer), allowing configuration for input, output, bypass, batteries, communications, language and operating modes. IST7 UPSs also feature a periodic self-cleaning function to expel impurities and reduce the risk of failure, with a large memory of up to 10,000 events that can be downloaded via the USB port integrated in the UPS.
UPS efficiency
IST7 UPSs have an efficiency of over 95% even at low loads, maximum output tolerance, ability to operate with 100% unbalanced loads, dual input with wide tolerance, compatible with diesel generators, advanced charging and maintenance system of 3-stage batteries and redundant and hot-swappable power modules (rectifier and inverter). In addition, the centralized bypass module with battery start button offers greater ease of use. The 50Hz-60Hz or 60Hz-50Hz converter mode and the possibility to disable the static bypass and the DC power supply of the inverter, offer further customization options.
UPS control
The IST7 UPSs are equipped with advanced communication for installation and operation with diesel generators and dry contact card alarms, configurable from the display, with periodic graphical recording of the waveforms relating to the inverter, rectifier and control. In addition, IST7 UPSs are equipped with bypass and control units, standard RS485 communications, Modbus and programmable dry contact card, as well as Input, Output and Bypass switches.
UPS accessories
By purchasing an AEC IST7 UPS (60-200 kVA) the Dry Contact Card is included in the price which supplies a series of normally open or normally closed potential-free contacts for report various UPS functions.
It is also possible to purchase various accessories separately to implement the functions of the UPS:
– External bypass = allows maintenance or repair/replacement of the UPS without interrupting the powered user.
– Temperature sensor = monitors the batteries by compensating the charge current based on the ambient temperature thanks to a probe that communicates with the UPS logic.
– SNMP card = allows AEC UPSs to be remotely monitored, serviced, tested and operated anywhere in the world.
In summary, the UPS IST7 | AEC UPS offers a wide range of customizable options, with a centralized modular design for easy expansion, high efficiency and reliability, a wide range of communication and control options, and numerous accessories and options to meet your needs. user specifications.
