NTE914 Integrated Circuit Zero–Voltage Switch
Description: The NTE914 zero–voltage switch is a monolithic silicon integrated circuit in a 14–Lead DIP type package designed to control a thyristor in a variety of AC power switching applications for AC input voltages of 24V, 120V, 208/230V, and 277V at 50/60Hz and 400Hz. The NTE914 incorporates 4 functional blocks as follows: Limiter–Power Supply: Permits operation directly from an AC line. Differential ON/OFF Sensing Amplifier: Tests the condition of external sensors or command signals. Hysteresis or proportional–control capability may easily be implemented in this section.
