TD-SCR uses the digital control technology to solve the flickering or non-shutdown problems of LED lamps during leading edge and trailing edge dimming. LED lamps are capacitive loads and often cause problems at the lowest dimming level due to insufficient holding current, leading to impulse-type flickering or failure to turn off LED lamps. TD-SCR ensures stable performance of IED lamps by maintaining the minimum output current when the conduction angle is smalest. It is ideal forload compensation in phase cut circuits.
