Electronic voltage stabilisers from 300 VA to 250 kVA

The fastest and the most accurate electronic regulation system of the market

In today’s electronic environment, saturated and highly unstable, where fluctuations in the power supply voltage are more than frequent, voltage stabilisers play a very important role in guaranteeing stable voltage to loads more sensitive to such variations.


The Salicru RE series of electronic stabilisers, based on a completely static structure of high efficiency, fast reply speed and excellent output precision, are made in single phase or three phase configuration and in a range of powers from 300 VA to 250 kVA.


The three-phase units are conceived with a completely phase-independent regulation in order to avoid possible regulation problems due to imbalance in the loads. Moreover, the units include a static bypass to guarantee the power supply in the event of a possible fault.

Technical specifications

Specifications - RE3 - SALICRU




Digital Ammetter

Digital Ammetter - SALICRU

An instrument for measuring the alternating input or output current. The reading is displayed in a digital way.

Max / min voltage protection with automatic reset

Max / min voltage protection with automatic reset - SALICRU

Protection against over and under voltages at the output of the stabiliser. To reset the protection is not necessary any action, it is automatic completely.

Manual bypass

Manual  bypass - SALICRU

Manual bypass and outgoing distribution module. Manual bypass is based on 5 position cam-switch combining inverter-static bypass-manual bypass. The outgoing distribution is based on four single pole circuit breakers.

Ultra-isolation transformer

Ultra-isolation transformer - SALICRU

Ultra-isolation transformer, based on a primary and secondary windings with both unit turns ratio and an earthed triple electrostatic shield for noise attenuation coming from mains (up to 140 dB on common mode).

Isolation transformer

Isolation transformer - SALICRU

Electrical device that provides galvanic isolation between input and output, and adjust tension.

Heating resistor

Heating resistor - SALICRU

A resistor located inside the equipment to prevent internal condensation.
