Three-phase voltage stabilizer of 120kVA (96kW) with 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 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 correct 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. 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 units consist of variac, servomotor controlling the variac, display controlling that motor and step-up transformer. The starting torque can be corrected quickly, even for very small voltage changes, thanks to the high DC servomotor and the control system that can respond quickly to voltage changes. Once the regulation is completed, the regulator is de-energized with the help of the highly efficient electronic braking circuit.
It incorporates Manual Bypass to perform 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 case of equipment failure, and thus obtain unregulated output power directly from the input mains, and for this purpose the other switch must be disconnected first.
Its main applications include computers, 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 sectors of application 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.The three-phase stabilizers of the M3 series are valid for photovoltaic applications, but it is important to take into account the following considerations:
- The power of the equipment must be oversized by 40%, due to the fact that current will flow in two directions.
- The voltage must always be within the regulation range marked in the specifications. Both in input and return at the output of the equipment.
- The equipment stabilizes the input. Network-Stabilizer-Inverter-Inverter-Plates, but does not stabilize the return of the excess of the plates that enters in the opposite direction.
- In three-phase, the phases must be balanced in consumption.
- The Neutral must be clean, 0V.
For use with
generator sets, the power of the stabilizer must be oversized by at least 40% of the capacity of the generator set.

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 lower than 0.8, the power in Watts will always be lower than indicated and will have to be recalculated.
Note: It is important to bear in mind that a voltage stabilizer does not solve all undervoltage or overvoltage problems in an electrical network, such as those where there are strong phase unbalances, strong presence of harmonics, open neutral (in three-phase systems there is 400V between F and N instead of 230V) or installations with poorly dimensioned cable cross-section.
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 output to ensure that the consumption demand never exceeds the capacity of the equipment.
