Universal timer is a mixed signal CMOS IC designed for a fixed timer to drive external SCR to implement safety power control. It is applied to 120V/240V and 50/60Hz AC power supply. It can automatically shut-off load in order to prevent undesired conditions from the system. Internal timer can present several kinds of different time 15mins, 30mins, 45mins, 1hr, 1.5hrs, 2hrs, 4hrs and 8hrs, which is decided by part number.
