100_volt_RMS_regulator_using_a_triac_and_UJT
100-volt RMS regulator using a triac and UJT. To eliminate 60-hertz modulation of the photocell it is mounted at one end of a black tube with the other end directed at the back side of the lamp reflector. The reflector glows red and since it has a relatively large mass it cannot respond to the supply frequency. This provides a form of integration (courtesy Motorola Semiconductor Products Inc.).   (View)
