<500VA
Uninterruptible power supplies within this size range typically use either standby or line interactive technologies. Applications tend to be small desktop systems, terminals, workstations and network peripherals.
UPS models include the Plug Dialog, iDialog, Net Dialog and Dialog Vision.
View table
500VA - 1KVA
At this size range applications tend to be file servers and local area network specific. UPS models include the iDialog, Net Dialog and Dialog Vision. For extended runtimes above the standard (typically 5-10 minutes at full load) a larger UPS must be installed. This will provide a longer runtime for the lower than capacity load. The alternative is to size the UPS and select on with a battery extension pack capability such as the larger models within the Net Dialog and Dialog Vision ranges. On-line double conversion UPS in the form of the Dialog Plus offer the facility for longer extended runtimes lasting up to seven or more hours without derating.
View table
1 - 4KVA
There are few line interactive UPS available above 1kVA. Riello UPS is unique in being able to offer a range of alternative models including iDialog, Net Dialog and Dialog Vision. The Dialog Plus range runs to 3kVA and offers options for extended runtime autonomies and remote monitoring. Above this size the Dialog Dual offers ideal power protection for data centres and server racks up to 10kVA.
View table
5 - 10KVA
Within this size range installations may require either a single phase or three phase input UPS. Dialog Dual and the Power Dialog Plus offer both single and three phase inputs and a single phase output as well as a host of customisation options for extended runtime autonomies and remote monitoring.
View table
10 - 20KVA
The Power Dialog Plus, Multi Plus and Multi Dialog UPS offer solutions within this category with both single and three phase inputs and single or three phase outputs. The Multi Plus and Multi Dialog UPS are also capable of parallel operation.
View table
20 - 40KVA
For this category consider the Multi Plus and Multi Dialog UPS. The Multi Plus currently runs to 20kVA and the Multi Dialog to 80kVA. A rack mount version of the Multi Dialog is available up to 30kVA and this can be run in parallel operation to provide a modular, scalable option. Master Plus (IND) offers an industrialised UPS option for process control environments from 10-80kVA.
View table
80 - 100KVA
Single UPS modules of the Multi Dialog are available up to 80kVA after which the UPS must be run in a parallel configuration to achieve higher power ratings. The Master Plus starts at 100kVA and is available as a three phase input and output system. For a three phase input, single phase output system within this range consider the transformer-based Master Dialog UPS.
View table
100 - 200KVA
The Master Plus is designed for data centre operation with 100kVA and 200kVA modules and offers a compact, highly resilient system.
View table
200 - 400KVA
The Master Plus is the optimum choice within this range. Consider running two systems in parallel to provide N+1 redundancy and a level of resilience. It is also common for these larger systems to be supported by a backup generator.
View table
400 - 800KVA
The mainstay of most data centre environments, the Master Plus provides an economic and efficient solution within this size range that can be scaled up through parallel operation to several MVA.
