Application areas
Solution suitable for multiple areas of application.
The voltage stabilizer-regulator is the most cost-effective solution to protect electrical, electronic, and computer equipment against temporary and permanent voltage fluctuations in the network.
It is a device that can maintain a constant output voltage (within tolerance limits) regardless of variations in the input voltage, within predefined limits relative to the nominal voltage.
To maintain a constant output voltage, it switches taps on a booster transformer in response to changes in the system voltage. Therefore, it adjusts the transformation ratio to regulate the output voltage.
To achieve this, it is equipped with a microprocessor control board that continuously monitors and controls the grid voltage, adjusting the output voltage to the correct value, thus protecting sensitive equipment and providing them with a stable and correct power supply.
Advantages of our solution
Compared to standard stabilizers available on the market, our StatiVolt® range offers the following advantages:
As a standard feature, the range of static voltage stabilizers corrects voltage sags within the voltage range of -25% to +15%, lasting 100ms or more, with a response time of around 20 milliseconds and a speed of 500 V/sec.
This range of stabilizers can also optionally offer wider voltage ranges, ranging from -60% to +40% lasting 100ms.
The device includes, as standard, protection against temporary or permanent overvoltages, undervoltages, overheating, overloads, phase losses, and short circuits provided by a thermal-magnetic circuit breaker at the input.
As an option, the device includes the following protections and features:
