The harmonics in electrical systems are electrical currents or sinusoidal electrical voltages that have a frequency equal to an integer multiple of the frequency of the distribution system, called the fundamental frequency. By overlapping the Fundamental Current and the Fundamental Voltage respectively, they cause the distortion of the waveform.
Voltage imbalances are one of the most common Power Quality problems in three-phase electrical networks. Being often overlooked, they can cause serious damage to electrical and electronic equipment.
One of the main factors to consider when choosing the right power supply for Xenon lamps is residual ripple, a phenomenon known in electronics and electrical engineering as “Ripple”. A low percentage of Ripple is synonymous with high quality DC power supply.

IREM: POSITIVE ENERGY,
WITHOUT INTERRUPTION. SINCE 1947.
“Quality is our first responsibility and customer satisfaction is our pride. The environment is our social objective, the safety and health of the individual is our duty”.
IREM is an Italian company, founded in 1947, worldwide leader in design and manufacture of equipment for the control and generation of electric energy.
Its brilliant founder, Mario Celso, as a boy passionate of electrical engineering and cinema, in the late 40’s succeeded to realize his childhood dream creating the first electromechanical rectifier for carbon arcs used in cinema projection.
From this first rectifier, a comprehensive line of products dedicated to power and strike gas discharge lamps will take shape.
Soon the production is enhanced with the introduction of voltage stabilisers, starting a line of products designed to develop quickly to a full range of equipment able to solve the mains power problems.
In the 50’s in addition to the energy management, IREM enters the field of machines for the production of energy: the first hydroelectric turbines, capable of generating renewable energy exploiting the head and flow of water streams are designed and produced .
In 1992, Mario Celso receives the Scientific and Technical Award for his technological contribution to the development of the film industry from the Academy of Motion Picture Arts and Sciences in Los Angeles.
ISO 9001 since 1991
ISO 14001 since 2000
BS OHSAS 18001 since 2014
Today, IREM is a protagonist on the international markets. The constant investments in research and development allow to maintain the highest quality standards by continuing to develop innovative products capable to meet the demands of prestigious customers.
Quality, Safety and Environment are Corporate Values that IREM has pursued since its foundation as the basis of its organization and its development.
