RE3 / RET — electronic voltage stabilizers 0.3–150 kVA
Country: Spain · Model: RE3 / RET
The static voltage stabilizers RE3 / RET cover powers from 0.3 to 150 kVA, and the datasheet gives the upper limit as 200 kVA. They are installed in front of CNC machines, in computing centers, at communication nodes and in laboratories where fast and accurate voltage correction is needed.

Description
The regulation is fully static, without moving contacts and brushes, so the stabilizer reacts to sags and surges faster than electromechanical models and has no wearing parts. The range includes single-phase and three-phase versions. In the three-phase ones each phase is regulated independently, so a voltage imbalance in the mains or an uneven phase load does not spoil the voltage on the other phases. The static bypass transfers the consumers directly to the mains in case of a fault or overload of the stabilizer, and the power to the machine or server is not interrupted. For a server room such a stabilizer complements a UPS and does not replace it, because it does not maintain power when the mains disappear completely.
How to choose
Power is selected from the total apparent load in kVA, taking into account the starting currents of machine motors. The single-phase models cover individual consumers from 300 VA, and the three-phase ones are needed for panels and shop lines. If the load exceeds 150 kVA, check the datasheet for the version up to 200 kVA or look at the servo-driven EMi3 from 5 kVA to 5 MVA, which is slower but has megavolt-ampere ratings.

FAQ
What is the power of the RE3 / RET stabilizers?
The range is from 300 VA to 150 kVA, and the datasheet gives the upper limit as 200 kVA. The exact rating is checked against the datasheet for a specific order.
How does the static RE3 stabilizer differ from a servo-driven one?
The RE3 has no moving parts, and the voltage correction is electronic and faster. The servo-driven EMi3 regulates the voltage with an autotransformer with a motor and is made up to 5 MVA.
Does the RET regulate each phase separately?
Yes, in the three-phase version the phases are regulated independently, so mains asymmetry is not passed to the stabilizer output.
What happens to the load when the RE3 stabilizer fails?
The static bypass moves the load to the mains directly, so the consumers stay energized until repair.
