100% brand new and high quality Features: LCD can display input/output voltage, output current/output power/output capacity. CNC adjustment, precise and fast, output voltage 0-36V arbitrary adjustment, output current 0-6.1A arbitrary adjustment. Anti-reverse connection protection of input end, which will not burn out. Output terminal short circuit protection, short circuit will not burn. It has multiple protection functions, such as over-voltage protection, over-current protection, over-power protection, over-temperature protection, and under-voltage protection. The default adjustment voltage or constant current value can be set, which can be adjusted quickly in various applications. Voltage and current can be locked to prevent misoperation. Using synchronous rectification technology, the conversion efficiency is high, the efficiency is more than 95%. Cautions: This is a step-up/step-down power supply module. The maximum input current is 12A. Therefore, the lower the input voltage, the lower the output power. The full-load output is 216W. The input power supply is required to be 20V-30V and the power is above 240W. When the voltage is lower than 2V, reduce the output current. Specifications: Product name: Power Supply Module Input voltage: DC6.0~30V (limit low voltage 5.5V, limit high voltage 35V) Output voltage: DC0.0V~36V Output current: 0.000A~6.100A Output power: 21 6W Output current limit: Maximum 12A Voltage resolution: 0.01V Current resolution: 0.001A Voltage accuracy: 0.4%+1 word Current accuracy: 0.5%+5 words Capacity: 0-999999AH Energy: 0-999999WH Time: 0-1000 hours Material: ABS Size: app.79x42mm/3.11x1.65in Optional Styles: A, B Color: As pictures shown Quantity: 1set Note: Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.
