Description

The UAA145 is a bipolar integrated circuit, designed to provide phase control for industrial applications. It permits the number of components in thyristor drive circuits to be drastically reduced. The versatility of the device is further enhanced by the provision of a large number of pins giving access to internal circuit points.

Features

• Separate pulse output synchronized by mains half wave

• Output pulse-width is freely adjustable

• Phase angle variable from >0° to <180°

• High-impedance phase shift input

• Less than 3° pulse symmetry between two half-cycles or phase of different integrated circuits

• Output pulse blocking

Applications

• Industrial power control

• Silicon controlled rectifier
