EMi3

Servomotor voltage stabiliser 5 kVA - 330 kVA

EMi3: Constant stabilisation and savings in overvoltages
Issues such as the constant variation of loads connected to the mains, interference generated by the loads themselves, possible failures
in distribution lines, voltage drops due to the length of the lines and problems caused by lightning make it impossible to have an electricity
supply with a stable voltage. Salicru’s EMi3 servomotor voltage stabilisers are the ideal solution to protect sensitive equipment from
constant voltage fluctuations in the power supply.
Moreover, in the event of drops in the total consumption of a power line, voltage tends to rise, causing overconsumption in the equipment
that remains connected. By using a stabiliser, overconsumption can be eliminated, thereby producing significant cost savings and ensuring
that connected loads function within the voltage range for which they were designed.
Salicru’s EMi3 servomotor voltage stabilisers are the culmination of 45 years of experience and development, in which the company has
manufactured and installed over 100,000 units worldwide.
The operating principle is based on regulation, by means of a control circuit, of the variable autotransformer that supplies the voltage for the
booster transformer in series, either in phase or in phase opposition, to achieve the rated value of the output voltage.

EMi3

Applications: Effective protection for all types of critical load
Actions and operations in electrical substations, electric ovens, numerical controls, lifts, graphic printing equipment, production
lines, medical equipment, TV repeater stations, machine tools (milling machines, trimming machines, presses, lathes, polishing
machines, electrical discharge machines, etc.) are some of the applications, because of their power, extremely reactive nature and
high sensitivity to voltage variations.
