Step-down module DC-DC 12V to 5V, 5A

This module can be used in the field of voltage reduction where the input voltage is higher than the output voltage, such as storage battery, power transformer, adjustable regulated DIY power supply, vehicle power supply, voltage reduction for industrial equipment, 12 V to 3.3 V, 12 V to 9 V, 12 V to 5 V, 24 V to 5 V, 24 V to 12 V, 36 V to 24 V, etc. The maximum output power can reach 75W, and it is recommended to use it within 50W. If the power exceeds 50W, please strengthen the heat dissipation.

The built-in voltmeter with input and output voltage indicator lights can fully display the status. The default boot output status can be set. (The default power-on state is "ON" or "OFF"). All set parameters will not be lost after a power failure. 

Overview:

• Input voltage: 5-36V
• Output voltage: 1.25-32V, continuously adjustable (Step-down mode: The input voltage must be at least 1 V higher than the output voltage)
• Output current: adjustable up to 5 A, 4.0 A recommended (The module does not have a constant current function.)
• Output power: up to 75 W
• Operating temperature: -40 to +85 °C
• Conversion efficiency: 96 % (The efficiency depends on the input and output voltage and the current)
• Load regulation ratio S (I) ≤ 0.8 %, voltage regulation ratio S (u) ≤ 0.8 %
• Operating frequency: 180 kHz
• Input and output voltage LED
• Overheating protection and short-circuit protection
• Emergency stop with only one button. (One button to switch off the power output)
• Dimensions: 7.43cm x 4.45cm x 1.87cm

Buttons:

• [ON/OFF] button: turn off the output power with one button and press and hold to set the default boot output state.
• [I/O] button: Switch the input and output voltage value display with one button and press and hold to exit the display. 
• [+] button: Touch the button lightly to increase the output voltage by 0.1 V and press and hold to increase the voltage by 1 V.
• [-] button: Touch the button lightly to decrease the output voltage by 0.1 V and press and hold it to decrease it by 1 V.

Scope of delivery:
