400W - Step Down Buck Module High Power Step Down Buck Converter 10V-60V for Battery ChargingLED Driving Beskrivelse

Dual LED indicators clearly show working status: power light for normal voltage output and red light for CC constant-current mode. Equipped with a large thick 46mm aluminum heat sink the bottom to sustain heavy-duty operation. Built-in constant current short-circuit protection prevents damage during short-circuit conditions.
Synchronous Rectification & High Efficiency.Synchronous rectifier reduces power loss, conversion efficiency to ~96%, stable and reliable operation.
CV/CC Stepless Dual Adjustment.Onboard potentiometers for independent adjustment of output voltage and current, flexible for various loads.
Dual LED Status Indicators.Power indicator for normal CV output; red CC indicator lights when constant current mode activates, easy status monitoring.
Thickened Aluminum Heat Sink & Protection.46mm tall large aluminum heat sink for thermal dissipation. Built-in constant current short-circuit protection to the module.

This 400W - high-power step-down buck module adopts synchronous rectification technology and large iron-silicon-aluminum toroidal inductor wound with double parallel copper wire to deliver high efficiency, high power and low temperature rise. It supports stepless adjustment in both Constant Voltage (CV) and Constant Current (CC) modes. Suitable for storage battery charging, high-power LED driving and step-down power supply for various equipment.
