Riello UPS Sentryum Rack SRM 20 online double-conversion

The Riello Sentryum Rack SRM 20 is part of the Sentryum Rack (20 - 160 kVA) range — ON LINE UPS. The Sentryum Rack range was specially developed to ensure power continuity in all sectors deemed critical due to the specific environmental conditions or industrial processes requiring protection. It is a true ON LINE double-conversion UPS, available in a 20 kVA/kW standalone version and in modular versions from 20 to 160 kVA/kW. The Sentryum Rack is available in both single-phase and three-phase output configurations. It accepts both single-phase and three-phase inputs with no need for special setups or operator intervention. The voltage arrangement could change during operation without any reset or manual operation, therefore the UPS auto-detects the input voltage and behave accordingly. This Series is derived from the Sentryum and essentially inherits its main technologies and peculiarities: The basic building block is a 20 kVA/kW module. Its connection clamps are laid out so that the communication signal connections are segregated and separated from the power connections (2 inputs, output, battery), thus ensuring complete immunity from interference generated by the power supply grid, which is typically disturbed in industrial environments. The module has a front-to-back airflow, realized by a smart ventilation principle, which manages the fan speed and airflow in accordance with the room temperature and load level. The Sentryum Rack cabinet is available in 2 versions, single-phase and three-phase output; it is designed to house up to 3 modules (60 kVA/kW) and up to 3 cabinets can be connected in parallel for a total of 8 modules and 160 kVA/kW of power. The Sentryum Rack cabinet has a distribution panel that contains all the devices to disconnect each module (3 input rectifier disconnectors, 3 input bypass disconnectors, 3 output disconnectors, 3 battery fuse holders), as well as maintenance manual bypass for completely isolating the 3 modules and guaranteeing power continuity to the load. Both modules and cabinets are provided with the bypass line separated from the rectifier line, by ensuring greater availability of the power supply to the UPS system and consequently extending this benefit to the load. The Sentryum Rack module can be used as a standalone unit or in a parallel configuration; by simply adding the parallel kit for each module, the UPS system can grow as requirements demand (from 20 to 160 kVA/kW). Every module is completely independent with regards to the control and management of the operator interfaces; this facilitates all monitoring, control and fault-detection operations, ensuring increased reliability in that any malfunctions in parts or accessory will not propagate through the entire system. Sentryum Rack ensures vertical scalability that minimises the system footprint, the user can thus have power capabilities from 20 to 60 kVA/kW for a single Sentryum Rack cabinet without increasing the footprint. The 20 kVA/kW module in standalone version is provided with input/output plug-in harting power connectors (2 inputs, output, battery) with threes meter length loose electrical cable to arrange the cabling according with the installation enclosure. These cables are not provided when the module is ordered to be fitted inside the Sentryum Rack cabinet, because they are already installed inside it as standard, for the maximum expansion of the cabinet.
