描述 Description

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.
