Uninterruptible Power Supply UPS: an increasingly large and varied need. In today's world, where the demand for electricity is constantly increasing, the quality and reliability of power lines are down.
Every day we are exposed to growing problems in the electricity network, such as grid failures, instantaneous overvoltages, and disturbances of various kinds from switching on medium and high voltage lines.
Each of these events can lead to disastrous consequences if you are not adequately prepared and protected. Business shutdowns caused by electricity problems cause damage to industries and service companies per billion euros each year.
Uninterruptible power supply UPS: what are they and what are they used for
An electronic device capable of sustaining the continuity of electricity to the loads is called an "uninterruptible power supply", better known as UPS, Uninterruptible Power Supply (System).
In a "UPS System", the source of the electric current is an inverter powered by the mains which, failing that, is supplied by a battery pack formed by batteries in series, or in parallel.
The use of a UPS is often a legislative obligation due to security issues.
According to a study conducted in 2006 by the Politecnico di Milano, the blackouts and voltage surges from the national network have caused the Italian industry average annual damage of about 580 million euros.
Too frequent is the recourse to uninterruptible power supplies only after these events have already occurred, when the first disasters have already happened, and the costs of these failures weigh on the costs of the company or the user.
UPS can perform:
- The function of supplying electricity in the absence of the main electricity network;
- Provide stable and uninterruptible power to the loads to be protected, supplying high-quality electricity.
There are two types of UPSs concerning the way they interact with the power supply and to the function performed:
- Double conversion Online UPS (VFI);
- Line Interactive UPS (VI).
AEC UPS series adopts both technologies: AEC Line interactive and AEC Online double conversion.
The IST1 UPS line interactive series covers all powers from 600VA up to 1500VA, mainly for offices and residential houses.
AEC concentrates on UPS with double conversion technology covering all powers from 1kVA up to 1000kVA, and AEC double-conversion UPS adopts the most advanced and reliable technologies on the market.
