Non-isolated step-down buck module with input voltage range 6~36 V and output 1.25~32 V for maximum current of 5A. Thanks to MPPT feature (Maximum Power Point Tracking), it is perfect for solar power circuits. DIY voltage regulator with constant current function, short circuit protection. Charging indicator LEDs: charging red, bright green when fully charged. Another LED is the output current detection. Over temperature protection: automatically cuts output when too hot. Input reverse polarity protection: None. Reverse current output protection: no, the output must be connected to the battery with a blocking diode, otherwise it will burn the module. Installation: 4 x 3mm screws. Technical data: Input voltage: 6~36 V Output voltage:1.25~32 V adjustable ( default 5V) MPPT voltage setting range: 6~36 V Output current range: 0.05~5A (The default output current is 3A) Operating temperature: -40~ + 85 degree Operating frequency: 180 KHz Conversion efficiency: up to 95% (efficiency, input & output voltage, current and pressure-related) Module dimensions: 6x3.1x2.5cm/2.36x1.22x0.98inch (without displays) https://elecena.pl/product/25645587/5a-mppt-dc-dc-buck-step-down-module 2024-03-28 https://elecena.pl/product/25645587/5a-mppt-dc-dc-buck-step-down-module 2025-10-29
