Description: 1. Realize high-frequency fast and frequent switching of the circuit, unlimited switching times. 2. There will be no noise during the on/off process, no sparks, no electromagnetic interference. 3. The service life is longer than that of common electromagnetic relays. 4. Double MOS parallel active output, lower internal resistance, larger current, strong power, 15A, 400W at room temperature, meeting the needs of most equipment. 5. Often used to control motors, light bulbs, LED strips, DC motors, micro pumps, solenoid valves, etc. Specification: Material: plastic + alloy Size: 60x36x13 mm / 2.36x1.41x0.51 inch Wide voltage operation (5~36V), most equipment can be used, very convenient. The interface is clear and simple, powerful and easy to understand, meeting almost all your needs. One button emergency stop function (STOP button), with reverse connection protection, reverse connection does not burn. Added sleep , after enabling, no operation within , automatically turn off the display; any button wakes up. Different OP, CL, and LOP parameters can be set. These parameters are independent of each other and saved separately. All setting parameters are automatically saved after power off. Package Includes:(3 Pack) 1 Piece automotive delay switch module
