SCM1501B Contactor Power Saving Controller Features        Package The input voltage is detected in real time, and the contactor operating voltage can be accurately set It can work in a wide input voltage range of 2.5:1 The pick-up current and the holding current can be set separately, and the contactor coil design is simpler With built-in analog frequency jitter, it is easy to solve EMI problems The chip’s power supply range is 16.5V~500V,which meets most of the contactor input voltage requirements With fast shutdown function, it reduces the contactor shutdown delay AC input busbar does not require large capacitance Product package: ESOP-8. Please see “Ordering Information” for details Applications   Various contactor power saving transformation Wide voltage AC/DC universal contactor control Functional Description The SCM1501B is a contractor power-saving controller that reduces the pick-up and holding power consumption of the contactor. The SCM1501B is a contractor power-saving controller that reduces the pick-up and holding power consumption of the contactor. The SCM1501B has a built-in high-voltage startup circuit that can quickly start the controller with a charging current of 4mA (typ.) within the The SCM1501B has a built-in high-voltage startup circuit that can quickly start the controller with a charging current of 4mA (typ.) within the inp input voltage range of 16.5V~500V, so as to respond quickly when the contactor is operated. If the auxiliary power supply is not used, SCM1501B will take power directly from the input to realize self-power supply. In addition, the SCM1501B can also control the contactor coil to achieve high current pick-up and low current holding. During the low current holding stage, when the input undervoltage occurs or the the controller is disable, the controller activates the fast shutdown function to quickly disconnect the contactor to reduce the influence of the SCM1501B on the disconnecting performance of the contactor.
