Installing a voltage stabilizer for each phase (in the absence of a three-phase load in a three-phase network) will avoid the situation of voltage loss in all three phases (unlike a three-phase stabilizer).

An advantageous offer for those who want to optimally protect their equipment and at the same time save their finances (when buying a kit, a significant discount). Such a kit will allow you to put protection on every important device or you can use it in a three-phase network.

Installation voltage stabilazer in a three-phase network for each phase will provide 25,5 kVA of power, and thereby eliminate the possibility of complete loss of the network. When connecting a three-phase load (machines, motors, etc.), it is enough to additionally install a phase control relay.

The connection of SUNTEK single-phase stabilizers to the three-phase network is carried out strictly according to the scheme.


It is important to know when installing SUNTEK single-phase voltage stabilizers in a three-phase network:

It is impossible to connect single-phase voltage stabilizers to a three-phase network if there is a three-phase load powered by 380 volts and there is no protective disconnection device (phase lock device). If three-phase devices will not be connected to the network, then the installation of single-phase stabilizers is quite possible.

When choosing a nominal value, it should be understood that if a three-phase voltage is supplied to you, for example, 15,000 VA, respectively, it is 5000VA for each phase. We recommend installing models 8500VA and higher in a three-phase network.
