Magnetic Voltage Booster for three-phase LV distribution networks
Magnetic Voltage Booster for three-phase LV distribution networks
Code: See Technical Characteristics
The Magnetic Voltage Booster (MVB) is a safe and reliable solution for three-phase LV power distribution networks, stabilizing and improving the voltage level in areas known to have voltage values below the normal limits, without high investment or major works, requiring one day for installation and commissioning.
