22.5kVA (18kW) three-phase voltage stabilizer with 400Vac output, electromechanical stabilizer driven by servomotor with independent regulation per phase for the control and regulation of network voltage drops and surges, provides a constant output voltage.
The equipment stabilizes the network 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 and thus achieving the appropriate voltage to power the connected load.
This equipment works fully automatically for voltage regulation without user intervention, which is achieved by continuously measuring the input voltage of the network and automatically carrying out the necessary up/down operations to provide the constant voltage necessary for a proper functioning. The integrated electronic control circuit measures the input voltage, deciding what the stabilized output voltage should be by comparing it with an internal reference sample value and with the applied load. This is why 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.
These devices consist of a variac, a servomotor that controls the variac, a display that controls that motor, and a booster transformer. Starting torque can quickly correct even very small voltage changes thanks to the high DC servo motor and control system that can respond quickly to voltage changes. Once the regulation is completed, the regulator is de-energized with the help of the electronic braking circuit, which has a high efficiency.
It incorporates manual bypass to carry out maintenance tasks 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 the event of equipment breakdown, and thus obtain unregulated output power directly from the input electrical network, and to do so the other switch must first be disconnected.
Its main applications include computing, audio/video equipment, telecommunications 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 found in industry, telecommunications, electrical supply companies, military applications, stock exchanges and banks, hospitals, supermarkets, shopping centers, financial institutions, airports, transportation industries, trains, railways, 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 power and that need to have a stable, clean and safe power network.
These devices provide the following features:
- User protection against negative voltages

Note: The power in Watts has been calculated based on an installation with a power factor of 0.8. For installations with a power factor less than 0.8, the power in Watts will always be lower than indicated and must be recalculated.
Note: The existence of a neutral is essential for the operation of the stabilizer.
Note: It is highly recommended to install a circuit breaker at the outlet to ensure that the capacity of the equipment is never exceeded in consumption demand.
