LAMP_TRIGGERED_SCR_GIVES_VARIABLE_PHASE_CONTROL_OF_POWER

Published:2009/7/20 7:34:00 Author:Jessie | From:SeekIC

Miniature 2128 lamp with low-mass filament triggers light-activated scr in 1 millisec when lamp is across scr and in about 3 cycles at low a-c lamp voltage. Potentiometer thus provides phase control of scr for dimming 25-w lamp or equivalent-wattage load.-E. K. Howell, Light-Activated Switch Expands Uses of Silicon-Controlled Rectifiers, Electronics, 37:15, p 53-61.
