One of the most powerful in the line of SUNTEK relay stabilizers, 100 Amper automat with bypass, lightning protection, full-power pulling coil from 140 Volts at the input, a microprocessor control circuit, a powerful terminal block, a forced cooling fan - a stabilizer filling that allows you to drop everything anxiety due to poor tension in the house.

It is in high demand among those living in the country (house, cottage), owners of small production sites, workshops, as well as owners of “demanding” equipment - power tools (compressors, pumping stations, HVAC equipment, etc.).

Installation in a three-phase network for each phase will provide 60 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 ability to connect a large number of pieces of equipment, electrical wiring throughout the house - makes this model indispensable for suburban life. The SUNTEK 20000VA voltage relay of the relay type possesses all the qualities of the SUNTEK relay line - reliability, simplicity, quality for reasonable money.

Loss of neutral protection

With this voltage stabilizer, we recommend installing our LOSS OF NEUTRAL PROTECTION SUNTEK development. This device protects your equipment from burning out if the voltage on the neural wire is lost. Overvoltage occurs mainly due to breakage of neutral conductors, when the supply voltage is distributed unevenly between consumers or due to errors of personnel serving the electrical network. An open conductor breaks or burns out when the electrical network is overloaded (the load on the network increases every year); under adverse weather conditions, when food is produced by an air line (wind, fallen tree); during short circuits in the electrical network; with poor contact at the junction of neutral conductors; when stealing non-ferrous metal (wire); with old wiring in the home network.

We recommend installing LOSS OF NEUTRAL PROTECTION SUNTEK in front of a voltage stabilizer, for example SUNTEK. At high voltages in excess of 285 volts, the voltage regulator disconnects the entire load from the power source, but remains itself at high voltage, waiting for a lower line voltage. To protect not only your house from burning, but also a voltage stabilizer, install such protection in front of a voltage stabilizer, and you will receive complete protection against any voltage fluctuations in the network. The stabilizer and LOSS OF NEUTRAL PROTECTION SUNTEK are synchronized at the same voltage, for example, for SUNTEK voltage regulators, this is 285 Volts, in this case it does not reduce the operating range of the stabilizer, LOSS OF NEUTRAL PROTECTION SUNTEK, but serves as its additional protection and protection against burning out the neutral conductor which has often become commonplace in cities and villages.
