Protection Mechanisms:
Input undervoltage protection (LUP): 11-125V adjustable, factory default value of 11V
Output overvoltage protection (OUP): 1-130V adjustable, factory default value 130V
Output overcurrent protection (OCP): 0.01-23A adjustable, factory default value 23A
Output overpower protection (OPP): 1-1500W adjustable, factory default value 1500W
Over temperature protection (OTP): 30-99 °C adjustable, factory default value of 60°C

Overcapacity protection (OAH): 0.001-9999Ah, factory default off
Superenergy protection (OPH): 0.001-4000KWh, factory default off


Caution:
1. It is not allowed to input AC power, let alone connect to 220V mains power.
2. The maximum allowable input voltage is 140V, and overvoltage input or reverse polarity connection is not allowed.
3. The output cannot fully guarantee anti backflow. When connecting the battery, it is necessary to ensure that the output voltage of the power module is always higher than the battery voltage, or to connect a diode in series with a unidirectional conduction at the output positive pole to prevent battery voltage backflow from burning out the power supply.
4. When connecting the output terminal to the battery, be careful not to reverse the positive and negative poles.
5. The product is a voltage reduction module, maximum output voltage = the input 
voltage * 0.95-1V.

Package List:
Step-down module * 1,
Color Display head * 1,
connecting cable * 1                    

Product Features:
1. LCD display board with gold sinking process to prevent oxidation and poor contact, ensuring a complete display even after long-term use.
2. Independent silicone keys for easy voltage or current adjustment with a simple one-key entry and exit system, eliminating complexity.
3. Display options include LCD header, color screen header, or the ability to add a custom serial screen for versatile functionality.
4. Utilizes a separate motherboard for flexible use, supporting stepless current and voltage adjustments.
5. Soft silicone button material provides a comfortable touch and durability, ensuring long-lasting performance without wear or failure.
