The best technology and protection for a strategic and innovative sector

In order for telecommunications companies to offer their services, they need a constant and reliable electricity supply. That is, a supply without power cuts, disturbances or fluctuations that can affect the normal operation of telecommunication devices.

To prevent this from happening and affecting the competitiveness of our work and wellbeing in our daily lives, uninterruptible power supplies (UPSs) have been developed, devices that Salicru started manufacturing more than 50 years ago.

Few sectors, like that of telecommunications, better reflect the technological progress of recent years and its contribution to the development of the information society.

 

Because to talk today about telecommunications is to talk about the technology related to television, radio, landline and mobile telephones, voice and data networks and the Internet. Certain basic services that, in the event of disruption, can have major consequences for the economy, security, health, transport, etc., not to mention the loss of confidential information stored in data centres.

 

Therefore, due to their fundamental role in society, these critical infrastructures require very high levels of reliability in their numerous security protocols. And among those security protocols, UPSs play an essential role.

Main electrical disturbances

In the telecommunications sector, the most common electrical disturbances are the following:

Spikes

Dropouts & blackouts

Sags & undervoltages

Solutions

To prevent these disturbances in the power supply from affecting the services provided by the telecommunications sector, Salicru has a catalogue of numerous solutions that can be adapted to the different needs of operators.

 

It consists of a range of devices that can work individually or as a complement, depending on the type of facilities to which they are connected, and offer alternating current supply continuity solutions, stability of output voltage, conversion of direct/alternating voltage and energy storage.

 

In short, these are solutions that guarantee 24 hours of stable power supply for systems as sensitive as those used by the telecommunications sector.

Modular technology: the latest evolution in UPSs

Salicru has a wide range of UPS systems whose features are ideal for large critical applications, such as telecommunications infrastructures, as they safeguard equipment and ensure the proper management of systems. In this sector, Salicru is firmly committed to modular UPS systems, devices that combine efficiency, flexibility, scalability, redundancy and reliability. These are devices that incorporate the most advanced technology, significantly improving the availability of energy and substantially increasing the security of classic power systems.

Modular technology: the latest evolution in UPSs

Modular UPS systems consist of a large number of modules connected in redundant parallel and represent the logical evolution of parallel UPSs. What are its advantages?

  • High reliability from manufacturing identical modules
  • Redundancy and high availability
  • Greater scalability
  • Improved module performance
  • Redundant static bypass
  • Intelligent system management
  • Drastic reduction of MTTR
  • Adaptability to any kind of facility
  • Optimisation of power converters
  • Cycling to equalise the operation of all modules

Modular technology offers an especially important advantage in data centre level and tier classification, enabling data centres to obtain high ratings (Tier III or Tier IV). And this is possible not only because of the strict specifications of the UPS used, but also because of the complete design of the DC environment, cooling system and electrical distribution to the critical loads.

 

Another advantage of modular UPSs is reduced total cost of ownership (TCO) and operational expenses (OPEX), thanks to the maximum energy efficiency of their structure and global system with proper management of it. The other aspect to highlight is reduced capital expenditure (CAPEX), mainly because the manufacture of large numbers of identical modules enables the development of an economy of scale which improves the manufacturing costs of UPSs and guarantees high price competitiveness.

Other security devices

In addition to a permanent power supply, current telecommunication systems also need devices that store energy as an alternative, as is the case of DC/AC systems or battery chargers, which also meet the needs of a wide variety of critical loads that have to be correctly powered and protected.

 

Particularly suited to the telecommunications sector are rectifiers and inverters, which help to provide a high-quality AC power supply from a DC power source.

 

This is Salicru’s response to the expectations and needs of a sector as dynamic and in continuous technological evolution as that of telecommunications, with devices that offer functionalities to a wide range of services.

  • Landline and mobile communications networks
  • Broadband networks
  • Data and telecommunications networks
  • Transmission and communications devices
  • Data centres (modular and virtualised)
  • Calculation centres
  • Document management centres
  • Server/communications racks
  • Unified communications (UC)
  • Routers, switches, hubs, etc.
  • Point-of-sale
  • CAD/CAM
  • Video streaming

‘The installation of a UPS in a completely new data centre represents between 3 and 5% of total expenditure’
