SINGLE PHASE ELECTROMECHANICAL VOLTAGE STABILIZERS WITH WI-FI CONTROL<\/h3>\n

We designed a new product that makes life easier for the user. The Wi-Fi network function is absolutely the biggest advantage of this device over similar devices.<\/h6>\n
With the Wi-Fi module on the voltage regulator, many parameters of the voltage regulator can be monitored, controlled or changed by connecting to a Wi-Fi network using any browser on a computer, tablet or smartphone.<\/h6>\n

The VSA1 stabilizers supply a constant voltage, correcting voltage drops and increases that occur on the network or in the internal structure of the electrical system.<\/p>\n

Our voltage regulators work automatically to regulate voltage without any user intervention.<\/p>\n

Once the regulator is turned on, the mains voltage is continuously measured and the necessary raise\/lower operations are performed automatically, providing the system with the constant voltage required for correct operation.<\/p>\n

Servo regulators consist of a variator, a servomotor that controls the variator, a multimeter with electronic management that controls the motor and the booster transformer.<\/p>\n

The motor’s high torque corrects quickly thanks to the DC servo motor and control system that can quickly respond to voltage changes.<\/p>\n

When the regulation is completed, the servomotor is de-energized with an electronic braking circuit.<\/p>\n

Electrical noise and transients do not disturb the regulation<\/p>\n

You can safely power any area that needs regular electrical supply without any problems.<\/p>\n

operating technology<\/p>\n

Single-phase electromechanical voltage stabilizers use a toroidal transformer (variable transformer), a BUCK-BOOST transformer, and an electronic circuit that controls the rotation of the variable transformer, thus regulating the output voltage. With the control system, in a very fast response time, the high-torque regulation motor regulates small voltage changes very quickly. The servomotor is put out of service by the limit switches when it is outside its operating limits and by the control circuit when the output voltage is automatically adjusted to the set value. When the regulation is complete, the motor’s energy is cut with the help of an electronic opening circuit, operating in complete silence.<\/p>\n

regulation system<\/h6>\n

The system is equipped with a bypass switch that allows the load to be powered with mains voltage in the event of a malfunction or need. Using the setting buttons you can adjust the output voltage, precision range, regulation speed, and high-low voltage limits. It is then possible to adjust the maximum current control and the relative hysteresis time. All settings can be password protected. A display shows the input and output voltage, and the current delivered.<\/p>\n

SINGLE-PHASE ELECTROMECHANICAL STABILIZERS \u2013 OPERATING PRINCIPLE<\/h6>\n

\"stabilizzatori<\/p>\n

The new VSA1 stabilizers offer features such as:<\/h6>\n

Protection of the user from dangerous or harmful voltages.<\/p>\n

Protection of user and device from excessive currents.<\/p>\n

Pure sinus RMS voltage regulation.<\/p>\n

Long-term overload protection and instant protection.<\/p>\n

AC voltage balancing with extreme precision.<\/p>\n

It runs smoothly on all loads from 0% to 100%.<\/p>\n

Manual change to bypass mode without adjustment.<\/p>\n

Displays all values \u200b\u200bin the bypass regime.<\/p>\n

Records input voltage and load current limits.<\/p>\n

Static, non-gradual, dynamically corrected output voltage.<\/p>\n

When protections are activated, it records the number of protection trips and the reason for each trip.<\/p>\n

Standard regulation is \u00b11% (227.7V -232.3V) stable when the input voltage is within the range<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
