Bare board size: 119x74x43mmHeader size: 86x45x50mm. Product model: XY12522Input voltages: 12.00~140.0V Output current: 0-22.00a.Output power: 2000WVoltages resolution: 0.01VStorage data groups: 10 groups Screen size: larger than 1.8inch LCD (38x29mm visual ranges)Conversion efficiency: about 95% Specifications: Component:PCB+Plastic MPPT function: Support MPPT solar charging. Output voltages: 0~125.0V Voltages accuracy: 0.5%+1 word Current accuracy: 0.5%+3 words Current resolution: 00.01A Number of key: 5 Buzzers: Yes. Soft start: Yes Typical output ripples: vpp-200mv. Precautions: 1. The input can't be connection with alternating current, and it can't be connection with 220V commercial power. 2. The maximumly input voltages should not exceed 145V, so it is recommended to use it within 140V, and the positive and negative poles should not be reversed. 3. The output have no backflow prevention. When connecting the battery, ensure that the output voltages of the power supply is constantly higher than the battery voltages, or connect the diode in series at the positive poles of the power supply to prevent the battery voltages from flowing backwards and burning the power supply. 4. When the output terminals is connection to the battery, be careful not to connect the positive and negative electrodes reversely. 5. The product is a step downs power supply with the maximumly output voltages = input voltagesx0.945. Package Includes: 1 Set Power Supply Module note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you donot mind befores you order. 2.Due to the differences between different monitors, the picture may not reflect the actual coloring of the item. Thanks for your understandings.
