This product is a dedicated transformer specially designed to match three‑phase contact‑less voltage‑stabilized power supplies.Each phase of every voltage stabilizer is equipped with three single‑phase transformers, whose output voltages are 6 V, 12 V and 24 V respectively. They are connected in series in the three‑phase circuit. Each phase is controlled by electronic components such as thyristors.By responding to variations of the input voltage, the output voltage is regulated to keep the three‑phase output voltage within the voltage‑stabilizing range.Featuring small size and light weight, this transformer is an ideal replacement for old‑style contact voltage stabilizers. It adopts contact‑less design, requires no maintenance, and has won high recognition among users.
