Broad Input & Fully Adjustable Output Range This module supports a wide DC input voltage of 5–36V, making it compatible with a variety of power sources such as 12V/24V adapters, lead-acid batteries, and industrial power supplies. It provides a continuously adjustable DC output from 1.3V to 32V, with the output voltage always limited to be less than or equal to the input voltage. The built-in high-precision adjustment knob and fine-tuning potentiometer allow you to set the exact voltage you need for applications ranging from low-voltage electronics to higher-power LED drivers. High Power Capacity with High Efficiency Built around the XL4016 switch-mode regulation chip, the module delivers a maximum power output of 200W and can handle a peak instantaneous current of 8A (with 5A recommended for continuous use to ensure reliability). Its conversion efficiency reaches up to 94%, significantly reducing energy loss and heat generation compared to traditional linear regulators. The high 180KHz switching frequency also helps minimize electromagnetic interference (EMI) and allows for the use of smaller, lighter passive components. Real-Time Dual LED Display for Safe, Easy Operation Unlike basic regulator modules that require external multimeters for monitoring, this unit features dual bright LED displays that show both output voltage and current in real time. Voltage is displayed with a precision of 0.1V, giving you instant, accurate feedback. This eliminates guesswork during adjustment, prevents accidental over-voltage or over-current conditions, and helps protect sensitive loads from damage. Comprehensive Built-In Safety & Protection Features The XL4016 core chip integrates multiple layers of protection: Over-voltage protection (OVP) to prevent output spikes Over-current protection (OCP) to limit load current Over-temperature protection (OTP) that shuts down the module if it overheats Short-circuit protection (SCP) for fail-safe operation Combined with a high-current Schottky diode (MBR20100CT) and copper-core power inductor, these features ensure stable, reliable performance even under variable load conditions. Robust Construction & Versatile Application The module is built with high-quality components, including large 470µF/50V input/output capacitors for clean power filtering and a black-coated aluminum heatsink for improved thermal management (a fan is recommended when operating above 5A). Its compact 78×63×40mm form factor, with clearly labeled screw terminals and mounting holes, makes it easy to integrate into projects. It is ideal for use in DIY power supplies, electronic repair labs, LED lighting control, battery charging systems, and hobbyist projects.
