SUNTEK Optima is a high-quality and reliable stabilizers for home and garden. They are distinguished by a wide range of input voltage (140-265 V), noiselessness and high speed. In the range from 160 to 250 Volts, they provide reliable voltage stabilization to a nominal value of 220 Volts ± 6%.
SUNTEK Optima thyristor voltage regulators are able to operate at temperatures from -40 °C to +60 °C (special version). All current-carrying elements of the stabilizer are additionally coated with a special varnish.
Indication of operating modes LED. An additional cooling system has been installed, which is activated when the load is exceeded by more than 50%. Universal metal case (floor / wall) with degree of protection IP20. To facilitate installation, a built-in cable of type PVA 3 meters long is provided.
PCU (Phase control unit or Phase synchronization unit) is designed for round-the-clock monitoring of a three-phase network according to the main parameters: phase imbalance (voltage difference in phases over 20%); the disappearance of one of the phases; Incorrect phase connection order. If one of these parameters is violated, the three-phase load is disconnected. The unit is recommended to be installed immediately before a three-phase load. Stand for installation of stabilizers is made of metal using a profile. It is painted with light gray powder enamel.
Three-phase thyristor voltage stabilizer SUNTEK is used to stabilize the voltage in the power circuit, to which three-phase equipment is connected. It is ideally suited for maintaining stable voltage in homes, cottages, offices, as well as on production workshops. It is important to know that the total power of all functioning equipment should not exceed 24000VA.
Three-phase thyristor voltage stabilizer SUNTEK consists of 3 single-phase stabilizers, which can be supplemented with a phase control unit and a special rack. This unit performs the following functions: provides control over the phase sequence, monitors the disappearance of one of the phases, as well as phase imbalance. In the event that at least one of the three indicated conditions necessary for the safe operation of the equipment is violated, the device automatically disconnects the circuit from the power supply. As soon as all functions are restored, automatic connection will occur.
The principle of operation of Three-phase thyristor voltage stabilizer SUNTEK
All 3 stabilizers included with this device work on the same principle. When the supplied voltage is in the range of 240-475V, the device regulates the output value discretely, giving the consumer a voltage of 380 volts. Power switches are switched in steps, and the device does not give interference to the mains. Efficiency is 98%. It runs silently.
Design features three-phase thyristor voltage stabilizer SUNTEK
The electrical circuit contains original design solutions that enable the device to withstand voltage surges up to 1000V. In this case, the operability of the device is maintained.There is additional current protection. If you load the stabilizer over the limit of power, the device simply disconnects from the power supply. As soon as the load is reduced to the permissible value, the stabilizer turns on automatically. There is also a system for protecting the autotransformer from overheating.
