Zero Voltage Switch
This series is designed for thyristor control in a variety of AC power
switching applications for AC input voltages of 24 V, 120 V, 208/230 V, and
277 V @ 50/60 Hz.
Applications:
• Relay Control
• Heater Control
• Valve Control
• Lamp Control
• On–Off Motor Switching
• Differential Comparator with Self–Contained Power Supply for Industrial
Applications
• Synchronous Switching of Flashing Lights

FUNCTIONAL BLOCK
DESCRIPTION
1. Limiter–Power Supply — Allows operation of
the CA3059 directly from an AC line. Suggested
dropping resistor (RS) values are given in the table
below.
2. Differential On/Off Sensing Amplifier — Tests
for condition of external sensors or input command
signals. Proportional control capability or hysteresis
may be implemented using this block.
3. Zero–Crossing Detector — Synchronizes the
output pulses to the zero voltage point of the AC cycle.
This synchronization eliminates RFI when used with
resistive loads.
4. Triac Drive — Supplies high–current pulses to
the external power controlling thyristor.
5. Protection Circuit — A built–in circuit may be
actuated, if the sensor opens or shorts, to remove the
drive current from the external triac.
6. Inhibit Capability — Thyristor firing may be
inhibited by the action of an internal diode gate at
Pin 1.
7. High Power DC Comparator Operation —
Operation in this mode is accomplished by connecting
Pin 7 to Pin 12 (thus overriding the action of the
zero–crossing detector). When Pin 13 is positive with
respect to Pin 9, current to the thyristor is continuous.

NOTES: 1. Care must be taken, especially when using an external power supply, that total package dissipation is not exceeded.
2. The values given in the Electrical Characteristics Table at 120 V also apply for operation at input voltages of 24 V, 208/230 V, and 277 V, except for
Pulse Duration test. However, the series resistor (RS) must have the indicated value, shown in Table A for the specified input voltage.
