Specification:
100% brand new and high quality Module Properties: non-isolated step-down module (BUCK) Input voltage: 4-38V Output voltage: 1.25-36V continuously adjustable Output current:0-5A Over 3A, attached the heat sink.(recommended for use within 4.5A for long time use) Output power: recommended for use in below 75W Working temperature:-40 to +85 degrees Operating Frequency: 180KHz Conversion efficiency: up to 96% Load regulation: S (I)<0.8% Voltage Regulation: S (u)< 0.8% Short-circuit protection: Yes (the limited current is 8A) Over-temperature protection: Yes (automatic shutdown when over-temperature) Input reverse polarity protection: No, (if necessary, please string into the high current diode) PIs input the polarity correctly. Installation: two 3mm screws Wiring: Welding, V-IN is the input, V-OUT is the output Dimensions: 54* 23*18 (mm) Applications: This module can be applied to a buck devices, such as batteries, power transformers, DIY adjustable power supply, 24V car laptop power, industry buck equipment, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V and so on. Notes: If you can not adjust the voltage, it may due to potentiometer is in too high resistance. need to adjust the potentiometer dozens times by turning anticlockwise, so that you can adjust the output voltage. Package Included: 1 x Mini Step down Power Module (With one heatsink)
