TAMURA Piezoelectric Ceramic Transformer SOLIDFORMER AS-A163T AS-A243T AS-313T AS-313TP 2W 3W 4W 6W

Description

Piezoelectric transformer (SOLIDFORMER®) can generate a high voltage by a low voltage input through the utilization of a resonance phenomenon of the piezoelectric transducer. The applications include high voltage power supplies,such as inverters for liquid crystal display back-lighting, dust collectors, copy machines, facsimile machines, ionaizer, and ozonizers.

Principle

The piezoelectric transformer has primary and secondary electrodes on the piezoelectric ceramic. The primary side is polarized in the thickness direction and the secondary side in the length direction. (Arrow mark shows polarization direction). When a voltage having a resonance frequency (Fr), determined by the length dimension, is input on the primary side, a strong mechanical oscillation is generated by inverse piezoelectric effect, and a high voltage (Vo) is output from the secondary side, matching its oscillation by direct piezoelectric effect.

Features

• High efficiency (above 95%).

• Inflammability.

• Thin thickness.

• No flux leakage.

• High reliability.

• Self control function of output current.

• Low harmonic current noise.

Cautions

- The unit may be damaged if a load is open when it starts driving.

- Characteristics will deteriorate when the unit is driven over the maximum rated.
