The undervoltage voltage stabilizer 12500VA SUNTEK Platinum is the best choice when looking for a reliable, high-quality stabilizer capable of making 220 Volts from 100 Volts. It is possible to install this model for the whole house (the total load should not exceed 12 kW) by connecting household or house appliances and technical equipment (pumping stations, septic tanks, heaters, etc.). Platimun series stabilizers can be used in production, in auto repair shops, farms as a supplier of reliable electricity with a voltage of 220 volts.

The stabilizer is made in a metal case and can be placed horizontally on the legs, or vertically on the wall (mount included with the stabilizer). A powerful coil, a relay in the amount of 5 pieces, a data management card for the relays are the three main components that make it possible to obtain the stated characteristics of the SUNTEK Platinum stabilizers of this series. Relay stabilizers do not require maintenance and additional costs, it saves users time and money.

From the SUNTEK relay stabilizers, the Platinum series models differ in addition to having a more powerful coil and 5 relays also with auxiliary equipment:

- forced cooling is carried out by 2 fans installed on both sides of the coil.

- bipolar circuit breaker - allows to divide the increased currents passing through the stabilizer at low input voltage.

The SUNTEK 12500 Platimun voltage stabilizer will work even from 90 volts, but it should be understood that the load level must be less than the nominal. Its full-fledged characteristics of the stabilizer begins to perform from 100 volts. At a voltage in the range of 270-285 Volts, the actual output voltage will also be shown on the display. But when reaching 285-288 Volt, the stabilizer will immediately turn off by turning off all devices (the letter “H” on the display), since the output voltage will be very high and dangerous for the equipment.

The electronic unit of the SUNTEK Platimun relay voltage regulator is a powerful enough microcontroller, in which the input and output voltage is analyzed and the signals for key management are generated.stabilizer. When forming the control voltage, the microcontroller takes into account the response time of keys and power relays. This allows switching without breaks. As a result, the voltage waveform at the output of the relay stabilizer repeats the shape at the input.

The SUNTEK Platimun voltage regulator will be your network status indicator from 90 to 285 Volts. If you are interested, follow the state of the network, if you do not have time - the stabilizer will control everything himself and give the best option for this situation.

The voltage stabilizer has protection:

Short circuit protection 
Overload protection (overheating) 
Undervoltage protection 
Overvoltage protection 
Protection against impulse (lightning) discharges 

Installation in a three-phase network for each phase will provide 37 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.

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.
