Our activities
DRTecnologie
was established more than 40 years ago to operate in development,
production and installation of systems and apparatuses for the conversion
and regulation of electric energy. From simple isolation transformers to
more complex static and dynamic UPSes for the supply of the auxiliary
apparatuses of a Thermoelectric Power Plant, our products are recognized
for reliability, quality and long life. This long years experience
permits us to assert our supremacy on the supply of these
systems in Italy and around the world. From Hospitals to
Telecommunication Centers, from Refineries to Defense Systems,
from Airports to Supercomputers, from Data Processing to Stock
Exchanges, everywhere is necessary to warrant continuity, reliability and
electric energy supply quality, our company is able to propose, since
40 years, a suitable solution.
Our history
Our company was founded in 1956 by Mr. Domenico Da
Ros. He was, until that time, director of the Power Supply Laboratories
of the Telettra Company (the most important italian manufacturer for
radiotelephony apparatuses); he decided to undertake a proper autonomous
activity dedicated to development and manufacturing of electric
conversion apparatuses, using, as regulating devices, magnetic
amplifiers. Our company produced, first in Italy, automatic alternators
regulators, completely static and made with magnetic amplifiers and
selenium rectifiers. The introduction in the market, during the first
’60 years, of large silicon diodes allowed the manufacturing of large
battery charger rectifiers (110 V – 500 A) completely static and
automatic; few years after was available on the market power thyristors
(SCR) and successively power transistors that allowed to develop
sophisticated static conversion systems from direct current to alternate
current that was manufactured in the past only using rotating machines.
The power semiconductor components’ evolution, during the following
years, strictly combined with highly sophisticated magnetic devices,
developed and produced inside our factory, had permitted to make
electric converters with commutation frequencies near to radiofrequency
(200 kHz); this characteristic is the key to reduce apparatuses’ volume
down to specific powers better than 200 W / dm3.
Since 1991 the
Da Ros S.r.l. company, that had the name of his founder, changed proper
denomination assuming the actual one.
Our track
The acquired experience
during 40 years of activities, permit us to face the future challenges
in a field that may appear so common. Some times the electric energy
supply is underestimated during the project of sophisticated automation
systems in the industrial, railways, information technology and
telecomunication fields. The fact that sometime the “plug” unplugs by
itself is too late to realize. Much better to apply to some expert, to
trust on, without the risk to buy very costly and probably very perfect
Uninterruptible Problems Source (UPS).
