diymore | PD QC Power Supply Distribution Board Module Simulator Module 5–20V Adjustable Voltage Module

Features1. One-button voltage adjustment with power-off memory: The white LED is on in standby mode when powered on; a short press switches the voltage; after power is turned off, the module automatically remembers and outputs the last set value2. Dual-digit (integer and decimal) fine-tuning: Supports 0.1V adjustments with LED flashing count feedback for precise output of any non-standard voltage3. Automatic polling test mode: Enter factory mode with a single button press; automatically cycles through 5V → 9V → 12V → 15V → 20V to quickly verify device compatibility4. Five-color indicator lights for clear status display: Yellow, blue, cyan, blue, and purple represent different voltage setting ranges, making operation intuitive at a glance5. Red warning light for safety and reliability: The indicator flashes red when output fails, allowing for immediate detection of abnormalities and preventing damage to downstream devices caused by voltage instabilityProduct IntroductionThis product is a smart, adjustable voltage output module that combines quick presets with fine-tuning, catering to both everyday use and professional debugging scenarios. You can quickly switch between commonly used voltages with a short press of a button, or use the advanced mode to independently set both integer and decimal values for precise 0.1V output. The device features a built-in LED interactive system that provides real-time feedback on the status of each operation step and comes standard with an automatic polling factory test mode, facilitating batch verification of device performance. Additionally, the one-touch reset function makes restoring factory settings quick and easy. Whether you’re an electronics enthusiast, a repair engineer, or a production line tester, you’ll enjoy an efficient, precise, and safe voltage regulation experience.ParameterThe product supports emulating any voltage between 5.0–20.0VYellow indicator: 5–8.9V (configurable)Green indicator: 9–11.9V (configurable)Cyan indicator: 12–14.9V (configurable)Blue indicator: 15–19.9V (configurable)Purple indicator: 20VPrecautions1. The charger must support the PD protocol. If it does not support PPS, it can only trigger fixed voltage levels such as 9V or 12V (e.g., 5–11V = 5A, 5–20V = 3.25A).2. Users with professional knowledge who modify battery chargers for use with this module must connect a diode in series (a virtual diode may be used).Package includeModule × 1
