The module uses a high-efficiency buck rectification system, and the maximum efficiency can reach 95%. Output voltage and current are continuously adjustable. Input voltage can reach up to 75 volts, and output voltage can reach up to 50V (when input is 75 volts). The maximum current is 25A. Wiring: If the power is high, the wiring should be as thick as possible. Conversion efficiency: up to 95% (efficiency is related to input and output voltage, current, and voltage difference); Short-circuit protection: Yes (constant current protection); Input reverse connection protection: No; Output anti-reverse feed: No (to charge the battery, the output is connected to an inductive load such as a motor, an anti-reverse feed diode must be added) Parameters: Module Name: 600W Step-down Constant Voltage Constant Current Adjustable Power Supply Module Module Nature: Non-isolated step-down module (BUCK) Input Voltage: 12-75V Output Voltage Range: 2.5-50V (step-down conditions must be met, IN input multiplied by 0.8) Minimum Output Voltage: 2.5V Output Constant Current: 1-25A (continuously adjustable) Maximum Output Power: 600W Continuous Maximum Working Power: 500W Continuous Maximum Working Current: 25A Voltage Conversion List: 12-75V to 5V, 14-75V to 12V, 12-75V to 9V, 17-75V to 14.8V, 19-75V to 16.8V, 22-75V to 19V, 24-75V to 21V, 28-75V to 24V, 35-75V to 30V, 41-75V to 36V, 48-75V to 42V, 55-75V to 48V Note: 1. This module is a step-down board and cannot be used as a step-up board. 2. If used to charge a battery or battery pack, add a diode at the output to prevent feedback. Different batches may have different appearances, but it does not affect the use.
