... These integrated circuit switches operate from an AC input voltage of 24, 120, 208 to 230, or 277V at 50, 60, or 400Hz. The CA3059 and CA3079 are supplied terminal dual- in-line plastic package. Zero-voltage switches (ZVS) are particularly well suited for use as thyristor trigger circuits. These switches trigger the thyristors at zero-voltage points in the supply voltage cycle ...

... Protection Circuit A special feature of the CA3059 zero-voltage switch is the inclusion of an interlock type of circuit. This circuit removes power from the load by interrupting the thyristor gate drive if the sensor either shorts or opens. However, use of this cir- cuit places certain constraints upon the user. Specifi ...
