Metering Devices -Switch Module Board Generic Brand Highlights Switch Module Board Description: IRF540 V2.0 MOSFET Switch Module + 4 Way MOSFET 4 Way MOSFET is an electronic device with good switching characteristics. It is widely used in circuits, such as switching power supplies, motor controls, lighting dimmers and so on. Relay is another type of module with switching characteristics. Since relay operates by relying on mechanical contacts to open or close. In this way, it will inevitably lead to the relay's operation stopping when the switching time is too short. And the sound of dad making over relay in certain situations is annoying. Specification: Size: Approx. 40x40x3mm / 1.57x1.57x0.12inch We designed a 4 channel MOSFET switch. It can provide up to four groups of electronic switches to control different circuit blocks respectively. Limited by working priciples, MOSFET can only be used to control DC circuit, such as DC-LED display and so on, but not suitable for controlling AC circuit. In some extreme cases, it can be used to control DC 100V/33A circuit. However, it is suggested that the controlled DC voltage is greater than 9V. Package includes: 10 pieces of MOSFET switch module
