This is the step-down voltage regulator unit.

Input voltage：4.5-35V
Output voltage：1.25-30V adjustable
Output current：constant 2A， Max 3A（with heat sink), heat sink must be attached when output is over 15W. (heat sink is not included in this unit)
Efficiency：Max 92%
Switching frequency：150KHz
Minimum voltage difference：2V (the output voltage is lower than input voltage)
Working temperature： -40℃ to +85℃ （output power within 10W ）
Output ripple：
Input 12V output 5V 3A 15mV(MAX)
Input 24V Output 12V 3A 40mV(MAX)
Wrong polarity protection: No, wrong polarity will burn the PCB directly.
Dynamic respond speed：5% 200uS
Short circuit protection：limit current, auto-resume

*This device is specially introduced to those experienced DIYers, basic electronic knowledge and DIY/welding skills are required, we are not responsible for damages due to lack of welding skills or wrong wirings etc.

*Check the output voltage and adjust the virable resistor to adjust the voltage if needed before connect to your device.

Includes:
1 x voltage regulator

* Wires are not provided, customers need to weld the input and output wires yourselves, so basic welding skills are required, also wrong polarity will cause severe damage to the unit.
