5A 10A 30A 1-6S PWM Electronic Switch 3.7-27V Input for RC FPV Models Airplane Lighting Controller Led Motor RC Switch Breaker5A/10A RC Controllable Switch This module is a nice little relay switch controlled by a backup auxiliary channel on the receiver. Ideal for switching lights, sound and other auxiliary electrical components. When PWM duty is more than 1500us, the switch will turn on; When PWM duty is less than 1400us, the switch will turn off. Specifications:RX Wire Length: 100mm Power Cord Length: 100mm (each)Load Current (DC) Switching:5A or 10A (Continuous Current)Input Voltage (DC):5-28V Normal ModeThe module can read the pulse width, which can be from 400 to 2600us. If the pulse width is greater than 1800us, the MOSFET switch will close, if it is less than 1200us, the MOSFET switch will open. Safe-Protection FeatureThis module has a secure protection feature that reduces the likelihood of unexpected activation. Under 2 conditions, the secure protection mode will be active:1. The pulse is greater than 1800us when the power is turned on for the first time, the MOSFET switch open. The LED will flash, you need to move the input to the off position, then normal more will be active;2. The signal is bad continuously for 500ms, MOSFET switch open. The LED will flash. When the signal is good, the device will turn off the safe protection mode. LEDThe normal mode: the LED will light up
