The module adopts a step-rectification scheme, achieving extremely high efficiency, with a maximum efficiency of up to 95%. Continuously adjustable output voltage and current. Maximum input voltage up to 75V, maximum output voltage up to 60V (when input is 75V). Maximum current 25A. Voltage regulation: According to the voltage required by the load, after powering on, the voltmeter is turned on and the output voltage is turned on at the same time (voltage potentiometer) and increase clockwise and reduce it inversely. Note: Installation guide not included, we strongly recommend you seek professional installation. Please check as much as possible to make sure the item is what you need. Product Parameters Module Name: 600W Adjustable Buck/Constant Voltage/Constant Current Power Supply Module Module Type: Non-isolated Buck Module (BUCK) Input Voltage: 12~75V Output Voltage Range: 2.5~60V (Must meet buck conditions, IN input multiplied by 0.8) Minimum Output Voltage: 2.5V Maximum Output Voltage: Approximately 0.8 times the input voltage (e.g., if the input is 40V, 40V + 0.8 = 32V, the maximum output voltage is 32V) Constant Output Current: 1~25A (Continuously Adjustable) Constant current regulation: The universal meter is short-circuit current regulation method: the output voltage of the module is adjusted to 5V, and the current potentiometer is twisted in reverse clockwise for about 20 turns (at this time, the module output has no voltage and then the output is output after 2 to 3 turns). The universal meter is turned on the current gear, and the meter is connected to the output end of the module, and the current potentiometer is twisted clockwise until the universal meter displays the current value you need.
