Overvoltage Protected Compressor Control
We can control medium power load, such as AC motors in home appliances, using ACST12 devices. Because of it’s thermal and turn off commutation performances, this device is able to drive an inductive load up to 12 A with no turn if additional snubber.
High thermal performances in static and transient modes such as the compressor inrush current or high torque operating conditions of an AC motor also provided by this device. The ACST1210-7 can be driven directly by a MCU through a simple gate resistor as shown in figure below because of it’s low gate triggering current level.
