RC Servo Tester ECS Consistency Speed Controler 2 switch 4CH Out for RC Helicopter Airplane Description: This product consists of a rotary switch and a DIP switch, simulating the joystick channel and DIP switch channel of an RC model remote controller. Both channels are independent. The DIP switch channel has three settings: high, medium, and low, indicated by three different colored lights. Specifications: Product Name: Dual-Channel PWM Signal Simulator, Servo Tester Application Scenarios: Servo testing, ESC testing, providing PWM signals to brushless motors for extended periods, and other applications requiring PWM signals. Operating Voltage: 5-8.4V High/Low Pulse Width: 1000-2000us Note: Each channel of this device has two interfaces, allowing connection to four devices simultaneously. This device can only be powered by a single power source. For example, when testing two ESCs, the UBEC of one ESC must be removed to prevent signal interference. Package Includes: 1x PWM Signal Simulator
