Features

Fast Response Time: Static voltage stabilizers consist of only electronic circuits (not moving part) hence it can correct output voltages at the high speed.

Continuity: Non-contact voltage stabilizers with automatic bypass function, make sure the load power supply is uninterrupted.

Independent Phase Control: All 3 phase static regulators with independent phase regulation.

Compact Size: Solid-state voltage stabilizers have compact size due to small size buck boost transformer. It is light in weight compared to servo AC voltage stabilizers and can save installation space.

Low Maintenance: In SCR based static voltage regulators there is no moving parts, no wear and tear hence low maintenance.

Silent Operation: Static stabilizers without mechanical parts, it is contactless and low noise level.

High Accuracy: Static thyristor-based voltage stabilizers regulators using electronic circuit to achieve precise regulation, ±1% tolerance available.

Main Parts

Main Control Board

It samples the output voltage, calculates the adjustment needed and sends the respective signal to drive board and scr.

Display Screen

It shows Input Voltage, Output Voltage, Output Current, Working Status, Frequency, etc. RS485 Port is available.

SCRs+Drive Boards

The quantity of thyristor may vary according to the power rating. Each phase with one drive board.

Buck / Boost Transformers

These transformers are standard dry type transformer that connected in series between the network and load.

Buying Guides

Calculate the kVA Rating. Evaluate the power consumption of the equipment or machine you will connect to the automatic voltage stabilizer. 3-phase kVA calculation: voltage x amperage x 1.732 / 1,000; 1-phase kVA calculation: voltage x amperage / 1,000. It is advisable to choose a thyristor voltage stabilizer with 25–30% additional capacity to handle extra load in the future.

Determine the Input (primary) and Output (secondary) Voltage. Input voltage is the voltage of the source electricity that needs to be regulated, output voltage is the voltage being supplied by the scr voltage stabilizer. Note that every different machine and appliance requires a specific voltage, Noyark scr based avr stabilizers ensure the incoming power supply is regulated and provides the precise output voltage you need.

Choose the Right Phase Number. 1-phase power is found in homes and small buildings, while 3-phase power is found in larger commercial and industrial settings.

Evaluate Input Voltage Range. Voltage fluctuations differ depending on geographical location and power supply quality. You need to identify: the lowest voltage your area experiences and the highest voltage recorded.

Check Neutral Line Availability. Wye (Star) or Delta connection. In star connection, there is four wire, three wires are phase wire and fourth is neutral which is taken from the star point. In delta connection, there is three wires alone and no neutral terminal is taken.

Choose Suitable Protection Degree. IP20, IP44 and above.

Identify Installation Conditions. It is necessary to know: indoor or outdoor installation; installation site altitude and climatic characteristics; ambient temperature.
