Three-phase voltage stabilizer of 22.5kVA (18kW) and 400Vac output. Servomotor stabilizer with independent regulation per phase to control the input mains voltage within regulation margins, providing a constant output voltage to supply any load with a clean, stable and safe voltage.

Automatic regulation of the mains input voltage, stabilizes the output voltage within ±1% to supply any critical load with a fully controlled and stabilized voltage by providing a constant voltage. It offers protection against overvoltages and very high voltage peaks from the mains without distorting the output waveform.


Part number: SRV-22,5K

Three-phase voltage stabilizer of 22.5kVA (18kW) and 400Vac output, electromechanical stabilizer driven by servomotor with independent regulation per phase for the control and regulation of voltage drops and rises of the network, providing a constant output voltage.


The equipment stabilizes the input mains voltage within very narrow regulation margins to supply any load at its output with a clean, stable and safe voltage. It does this by continuously monitoring and sampling the input and output voltages to achieve the proper voltage to supply the connected load.

This equipment operates fully automatically for voltage regulation without user intervention, which is achieved by continuously measuring the mains input voltage and automatically performing the necessary step-up/step-down operations to provide the constant voltage required for normal operation. The integrated electronic control circuit measures the input voltage and decides what the stabilized output voltage should be by comparing it with an internal reference sample value and the applied load. That is why the stabilizers are used to power equipment sensitive to voltage variations or to solve problems in installations with large voltage variations due to problems in the supply line.


It incorporates a manual Bypass for maintenance or to continue feeding the loads in case of equipment failure, it does not distort the output sine wave. The Manual Bypass Switch should only be connected in case of equipment failure, and thus obtain unregulated output power directly from the input mains, and for this purpose the other switch must first be disconnected.



Among its main applications we can highlight the computer, audio/video equipment, telecommunication systems, medical and clinical analysis equipment, security systems and surveillance cameras, critical electronic circuits and boards, lighting systems, household appliances, home automation, etc..

Other application sectors are in industry, telecommunications, power supply companies, military applications, stock exchange and banks, hospitals, supermarkets, shopping malls, financial institutions, airports, locomotive industries, trains, railroads, shipping industries, production lines and automatic calculation, textile and paper industries, ... and in general in all those applications that have a very critical load to feed and need to have a stable, clean and safe power supply network.
