Helios Power Solutions announces the launch of the New Riello Sentryum Rack, a modular UPS solution for industrial applications requiring high level of operational reliability. It combines the characteristics of the hugely popular Sentryum Series, namely performance, high efficiency and compact footprint, with the simple “pay as you grow” scalability of a modular power backup system.
Sentryum Rack is the perfect solution for use in factories, manufacturing plants and other facilities where there are tough industrial processes or harsh environments conditions.
Modular Double Conversion Industrial Power Backup Solution
The rack mount version of the Sentryum UPS unit was designed for use in all sectors of the market whether industrial or otherwise; it offers optimum power protection and backup.
Available with single-phase or three-phase output, the UPS has an operating efficiency of up to 96.3% in online mode and the ability to deal with sudden load peaks without having to transfer to bypass.
Plug and play 20kVA power modules
The plug and play Sentryum Rack incorporates a sophisticated battery management system, while it is compatible with alternative energy storage solutions such as supercapacitors or lithium-ion batteries. It also features a large touchscreen colour display panel and an intuitive LED status indicator that automatically changes colour depending to the current status of the UPS.
The individual modules, which can be either single-phase SRM (Sentryum Rack Mono-Phase) or three-phase SRT (Sentryum Rack Three-Phase), are compatible with the normal standard 19-inch cabinets in networking and industrial environments; while the Sentryum Rack cabinet models (equipped with switch panels) up to 60 kVA / kW can be installed with 3 modules of 20 kVA / kW, with the possibility of reaching a total of 160 kVA / kW with several cabinets installed in parallel. The possibility of creating parallel systems up to 160 kVA / kW is however guaranteed even with standard 19-inch cabinets.
Robust & Independent Power Connectors for Industrial Applications
The power connections are managed by sturdy Harting cables and plug & play connectors specifically designed to operate in harsh industrial environments, which ensure simplicity and safety when inserting and removing them.
The connection terminals of the modules are arranged in such a way that the connections of the communication signals are isolated and separated from the power ones (input, output, bypass line, battery) thus ensuring complete immunity from disturbances generated by the power supply network. This particular feature makes them suitable for industrial environments where it is common for the network to be disturbed.
Sentryum Rack also guarantees great flexibility and simplicity during both the maintenance or replacement phases of a module, and when an additional UPS module is added to the system to increase the available power or redundancy.
