UPS backup systems (Uninterruptible Power Supply), are devices capable of interacting at all times with the public network or who supply them with power and operate at a certain moment of power failure. It is an intelligent electronic system capable of extracting energy from their stationary batteries and through an inverter delivers clean, stable and pure sinusoidal energy to their connected loads, in order to protect and safeguard the critical systems of normal company processes.
The On Line Double Conversion UPS technology is the latest in efficiency and security of supply given that, as its name indicates, On Line is permanently monitoring the supply from the public network and delivering a parallel energy from its inverter, in order to reduce to a zero time the synchronism of step to battery backup. The denomination Double Conversion, is basically to pass of energy; alternating – continuous – alternating, from the rectifier, batteries and the inverter, this step of alternating and continuous power and then again alternating, is the key to the quality of energy that trains the UPS systems, since it is ensured that the impurities and distortions of the public network are canceled by this system of double energy conversion and the UPS is able to deliver a renewed energy, pure sinusoidal, stable and without distortions.
The capacities of single-phase UPS range from 1KVA to 15KVA and in UPS for 3 Phase (เครื่องสำรองไฟ 3 Phase, which is the term in Thai) from 10KVA to 300KVA, and for higher capacity solutions it is possible to install in parallel in such a way to add power modularly in capacity according to high requirements. Nowadays 3 phase UPS backup equipment is able to support a large amount of power and critical systems, such as: data centers, banks, power plants, electrical rooms, laboratories, communication and CCTV, industrial monitoring systems, among others.
