In stock specifications: The maximum current is 8–9 A, the maximum input voltage is 40 V, and the maximum output voltage is around 35 V.
Due to the 12A current-chip manufacturer ceasing production, the replacement chip’s current rating has been reduced from the previous 12 A to 8 A (the maximum current measured in actual tests is around 9 A). The input voltage has changed from the previous 32 V to 40 V, and the output voltage has changed from the previous 28 V to 35 V. It can supply power to 10 strings of high-power LEDs. We will provide further notice upon arrival of the 12A chip.
Adjustable power supplies (with a robust 12 A rating), high-power LED drivers, LED display drivers, lead-acid battery chargers, lithium-battery chargers, automotive power supplies, in-vehicle laptop power adapters (step-down), regulated power supplies, and low-voltage system power supplies—for example, stepping down a 12 V battery to 6 V for children’s toy cars—as well as 24 V to 12 V at 12 A, 12 V to 5 V at 12 A, 24 V to 5 V at 12 A, 24 V to 19 V/20 V, and more—making these solutions applicable across an extremely wide range of applications.
The constant turn-light current is set to 0.1 times the constant-current value (used during charging to determine whether the battery is fully charged).
A dedicated reference IC and high-precision sampling resistor are used to ensure more stable constant-current operation (with a temperature drift of less than 5% when maintaining a constant current of 5 A over the temperature range of 20°C to 60°C). Especially suitable for LED drivers.
High output current: the maximum output current can reach 12 A, meeting the needs of most applications.
Four high-frequency capacitors effectively reduce output ripple and enhance operational stability.
Dual heat-sink design: separate heat sinks for the MOSFET and the Schottky diode, ensuring excellent thermal performance without mutual interference.
Employ large-size iron-silicon-aluminum magnetic cores at any cost to enhance operational efficiency, and use pure copper bifilar winding to reduce heat generation and further improve efficiency.
3296 multi-turn potentiometer with high voltage and current adjustment accuracy and excellent stability.
Dedicated current-sensing shunt resistor: high measurement accuracy, excellent stability, and low temperature drift. Essential for LEDs.
Dual-color indicator light for clear status visualization. Essential for charging.
Both voltage and current are adjustable, making it an excellent adjustable power supply; the 12A current rating provides ample power.

The main chip currently used in this power supply module is the XL4016.
The 12A current-chip manufacturer has ceased production. The replacement chip has a reduced continuous current rating of 8A (measured up to 9A in actual tests), but benefits from an increased input voltage capability of 40V and output capability of 35V.
An active cooling fan is required if the power transistor temperature exceeds 65°C, or when operating at sustained output currents above 6A in enclosed or high-ambient-temperature environments.
Yes. It features dual independent potentiometers that allow you to set both the output voltage (CV) and current limits (CC) for charging batteries or driving LEDs safely.
No, there is no built-in input reverse polarity protection or output backflow prevention. For battery charging, it is highly recommended to install external blocking diodes to prevent damage to the module.
