Zero Voltage Switch with Fixed Ramp
Description
The monolithic integrated bipolar circuit, TEA1024/
TEA1124 is a zero voltage switch for triac control in
domestic equipments. It offers not only the control of a
triac in zero crossing mode but also the possibility of
power control. This is why the IC contains a mains
synchronized ramp generator with 640 ms (1280 ms)
duration (50 Hz). It is suitable for a typical load of 750 W
(1000 W) meeting the Flicker Standard. (values in
brackets relate to TEA1124.)
