Return Policy Returns are not accepted Ask Seller a Question Report Seller Description ESC Digital Servo Tester & Motor Controller Board ▷ Description This item can be used to generate a PWM signal to drive ESC and brushless motors. It can generate 4-ways PWM signals to control 4 pieces of servos synchronously. The precision of Output signal(PWM) is up to 2us, and output signal width is accurately display on LED-Display,  you can test subtle movement of servo via rotating the potentiometers. There are three modes available, they are "manual mode"，"bit mode" and "automatic mode".  you can switch modes by "select" key.when the power is on, it enters "manual mode". Manual mode: The signal width is adjusted by hand via rotationg the potentiometer. Bit mode: The signal width is returned to the neutral point(1500us) Automatic mode: The signal width will decrease or increase automatically, This is useful for aging test of servo. The output signal frequency can be set to 50Hz/125Hz/250Hz by "pulse Width" key. 50Hz: suitable for analog servo and ESC, signal cycle 20ms, frequency 50Hz. 125Hz: suitable for digital servo, signal cycle 8ms, frequency 125Hz. 250Hz: suitable for digital servo, signal cycle 4ms, frequency 250Hz. Please Note: Please first select the corresponding signal frequency for servo, then connect it to servo to avoid damage to the servo. ▷ Specification & Features - Input voltage: DC 5-6V - Output signal width: 800-2200us - Package size: 14 * 10 * 3cm / 5.5 * 3.9 * 1.2in - Package weight: 39g / 1.4oz ▷ Item Contains 1 piece of Digital Servo Tester ESC Tester PWM Regulator Reviews (0) Currently there are no reviews for this product.
