EMi3 — servo-driven voltage stabilizer 5 kVA – 5 MVA
Country: Spain · Model: EMi3
The servo-driven EMi3 stabilizer is made for powers from 5 kVA to 5 MVA, from a single single-phase consumer to the main input of a whole enterprise. It levels the voltage for sensitive equipment and saves energy, because it removes overvoltage at the consumers.

Description
The voltage is regulated by an autotransformer with a servo drive, which through a booster transformer adds or subtracts the needed share of the mains voltage. The motor moves the current collector smoothly, so the output voltage changes without steps. Such a scheme scales well, which is why the range reaches the megavolt-ampere class. The single-phase models of the M series have ratings of 5–65 kVA and suit individual lines, offices or laboratories. The stabilizer status is sent over Modbus to the Argus program or to the SCADA of the enterprise. When the mains voltage is constantly too high, the stabilizer lowers the voltage at the consumers to the nominal one, and motors and lighting stop consuming extra.
How to choose
The rating is chosen by the full load power with a margin for starting currents. For a single-phase line take the M series of 5–65 kVA, and for the three-phase input of a shop or building the three-phase versions up to 5 MVA. If the load is critical to reaction speed, like CNC machines or measuring benches, the static RE3 / RET of 0.3–150 kVA is more appropriate.

FAQ
What is the maximum power of the EMi3 stabilizer?
The range starts at 5 kVA and ends at 5 MVA. The single-phase M models cover 5–65 kVA.
How does the servo-driven EMi3 stabilizer work?
A servo motor changes the position of the current collector of the adjustable autotransformer, and the booster transformer adds or subtracts voltage in the line. The regulation is smooth, without steps.
Can the EMi3 be connected to a dispatching system?
Yes, the stabilizer sends data over the Modbus protocol, which the Argus monitoring program works with.
Does the EMi3 save electricity?
The manufacturer positions it also for energy saving. When the mains voltage is too high, the stabilizer removes the overvoltage, and the consumers do not work at increased voltage with excess losses.
