2PC 400W 15A DC-DC Step Up Down Boost Buck Voltage Power Converter Module Supply

2PC 400W 15A DC-DC Step Up Down Boost Buck Voltage Power Converter Module Supply Description: 400W 15A DC-DC Power Converter Boost Module Step-up Constant Power Supply Module 8.5V-50V to 10V-60V LED Boost Module Features: This is a great 400W DC to DC step-up power supply module for electric equipment, digital products, laptop, etc. Input and output are designed with screw terminals for convenient wire connection and disconnection. High efficiency, the maximum conversion efficiency can be 96% and efficiency is related to input/output voltage, current and voltage difference. There are 2 heat sinks that would ensure a better heat dissipation. It can also be used as a driver for high power LED lights or voltage regulator for solar panels. Specifications: Type: Non-isolated boost module Input Voltage: DC8.5V to 50V Output Voltage: DC10V to 60V (continuously adjustable, default 19V) Max. Input Current: 15A (please enhance heat dissipation if more than 8A) Max. Output Current: 12A (related to the input and output voltage difference, the greater voltage difference is, the smaller output current will be. please enhance heat dissipation when current is over 7A) Quiescent Current: 10mA(will increase when convert 12V to 20V) Constant Current Range: 0.2A to 12A Maximum output power: = input voltage*10A, such as: input 12V*5A=60W, input 24V*5A=120W, input 36V*5A=180W, input 48V*5A=240W Operating Temperature: -40° to 85°(if temperature is too high, please enhance heat dissipation) Frequency: 150KHz Max. Conversion Efficiency: 96% (Efficiency is related to input/output voltage, current and voltage difference Over Current Protection: Yes (if input current is more than 15A, it will automatic reduce output voltage) Reverse Input Protection: No Output Voltage/Current Adjustment: 1. Adjust “CV-ADJ” potentiometer clockwise to reduce voltage, counterclockwise to increase voltage. 2. Adjust “CC-ADJ” potentiometer counterclockwise about 30 circles to minimize the output current before connecting to load(clockwise to increase current, counterclockwise to reduce current). Then adjust “CC-ADJ” clockwise to the current value you need. If you use the module for battery charging, connect to output after battery is fully discharged. Because if the more energy is left in battery, the less charging current will be. Package Includes: 2 X Converter Boost Module NOTE: *SORRY!
