Features: 1. Warm Reminder: The Module Is An Accessory, Not A Finished Product. Please Have Certain Professional Knowledge To Use It To Avoid Unnecessary Losses. 2. When Using Currents, Please Properly Match Thickened Wires And Secure The Terminals. 3. The Module Without Constant Current Cannot Be Directly Used For Output Charging. 4. Minimum Voltage Drop: Minimum 5V, The Higher The Input Voltage, The Lower The Minimum Voltage Drop Will Increase. 5. DC-DC High Power And High Voltage Adjustable Module Description: 1. Name: Non-isolated adjustable module 2. Input voltage: DC25-90V 3. Output voltage: DC2.5-50V adjustable, suitable for applications where the output voltage is lower than the input voltage and cannot be boosted. 4. Output current: 35A, used for power tools with a current of 50A, long-term use of currents such as modules 5. If the temperature exceeds 75 degrees, ventilation and heat dissipation need to be increased. 6. Output power: 1000WMax Note: Different Batches May Have Differences In Product Appearance, Color, And Printed Characters, Which Will Not Affect The Use Dimensions with housing: 98 x 130 x 41mm Material: PCB colour: As shown Package Contents: 1 x Module Only the above package content, other products are not included.
