Input Voltage: 5-32V (not exceed 38V); Output Voltage: 0.8-24V (continuously adjustable) Input Current: 0-5A (Suggest to use less than 3.5A for long time working); Output Power: 75W (Max) Please strengthen the cooling when the output is over 50W. Working Temperature: - 40 degrees to + 85 degrees, with power indicator light, overheat protection, but there is no reverse voltage protection. Adopting large power magnetic encircling inductance and large current driver chip, the transfer efficiency reaches 92. Small size, large power, high efficiency, applied to DIY mobile power supply, vehicle power supply, communication equipment power supply, LED power supply, etc. Feature: Name: DC-DC 5A Step-Down Power Supply Module Type: Non-isolated step-down module Rectification mode: Non-synchronous rectification Input voltage: 5-32V (not exceed 38V) Output voltage: 0.8-24V (continuously adjustable) Input current: 0-5A (suggest to use less than 3.5A for long time working) Output power: 75W (Max) Please strengthen the cooling when the output is over 50W. Working temperature: - 40 degrees to + 85 degrees Working frequency: 300KHz Transfer efficiency: 95 (max.), referring to input voltage, output voltage, current, dropout voltage. Load Regulation: S(I) less than or equal to 0.8 Voltage Regulation: S(u) less than or equal to 0.8 Power Light: Yes Overheat Protection: Yes, automatically cut off the output once the temperature is too high. Reverse Voltage Protection: NO (If needed, please add a large current tube.) Installation: 2x3mm screws Connection Mode: Soldering, V-IN for input, V-OUT for output Adopting large power magnetic encircling inductance and large current driver chip, small size, large power, high efficiency, applied to DIY mobile power, vehicle power supply, communication equipment power supply, LED power supply, etc. Package Includes: 3 x 5A XL4005E1 Step-Down Buck Regulator Power Supply Module Color: As the picture shown Size: 43.18 x 20.83mm.ladace
