Voltage Stabiliser

Salicru Voltage Stabilizer

1) Electronic Voltage Stabilizer (RE Series):

RE electronic voltage stabilizer are implemented on the basis of an autotransformer with multiple sockets taps per phase, connected electrically to a solid state switch and controlled by a microprocessor control board controlling the output voltage and depending on the level of this, selecting one tap or another in order to achieve the optimal voltage level with preset accuracy. They also include a servo system that compares the output voltage instead of controlling the input voltage, thus achieving a faster response time.

Additional Isolation transformer is available for the Power Line Conditioner. This galvanic isolation transformer, with low capacity primary-secondary windings, restores the neutral of the installation and eliminates all kinds of electrical noise (up to 120dB signal/noise ratio), acquiring line conditioner function.

The RE series are available from 1kVA single phase to 200kVA three phase. It is recommended for all electronic device susceptible to voltage variations and/ or electrical noise. Among other possible applications, we highlight:

Ordering and calculation centers
Computer peripherals
Office computer devices
Transmission and communications equipment
Control and production process equipment
Numerical control machines
Laboratory equipment
Electronic equipment
Photographic process and control

The RE series in its three-phase version is independent phase regulation: each of the phases is dealt with individual through the Electronic Unit, which is managed through a state-of-the-art micro controller that directs the whole operation of the Stabilizer.

2) Servomotor Voltage Stabilizer (Emi series):

The EMi stabilizers provide great overload capacity (up to 1000%), high output accuracy, strength and reliability, which make it the ideal stabilizer for feeding difficult loads (inductive and capacitive loads, loads that vary over time, etc.).
The electronic control is based on a powerful microcontroller, which permanently supervise the output voltage of the stabilizer, thereby providing a correction signal to the stepped motor, in case the output voltage is incorrect. The motor controls the ARC variable auto-transformer, where it increase or decrease the voltage by moving the variable tap slider in one direction or the other. The resulting voltage is applied to the primary of the "Booster" transformer, which adds this voltage on the phase or counter-phase to the mains through the secondary of the "Booster" transformer, thereby correcting any fluctuations over the nominal voltage that may occur.

Servomotor controlled voltage stabilizer, Emi single-phase series.

(dimensions and weight for models: input 230V 50Hz/ Output 230V 50Hz)

As regards the common control three-phase stabilizer, a single control averages the voltages to be corrected between phases, thereby operating a single motor, which moves the variable tap slider of the three phases and corrects any existing deviations with respect to the nominal voltage on the commercial mains.

As regards the independent phase control three phase stabilizer, the equipment is constructed using three single-phase stabilizers with separate controls per each phase. In this way, each one of the phases is adjusted with respect to the neutral, at the nominal voltage, and it therefore does not modify the voltage of the other two, regardless of the load percentage applied to each phase.

Emi series are available from 2kVA single phase to 500kVA three phase.
