22A/1400W Buck DC Adjustable Voltage Regulator Voltage Current Module Constant Voltage Constant Current Step-down Module

Features:

1. LCD display board gold plating process to prevent oxidation and poor contact, and to prevent incomplete display after prolonged use
2. Independent silicone button to set voltage or current, one click to enter and one click to exit, fast and concise, rejecting tedious tasks
3. There are multiple ways to play with the monitor, which can be equipped with our LCD meter head, color screen meter head, or equipped with a serial port screen
4. Flexible use of individual motherboards, supporting stepless current and voltage regulation
5. The silicone button material is soft, comfortable to touch, and has an excellent hand feel. Compared to mechanical buttons, they can withstand long-term use and frequent pressing without wear or failure, making them more long-lasting and have a longer service life

Notes:

1. It is not allowed to input AC power, let alone connect to 220V mains power
2. The maximum allowable input voltage is 75V, 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 the output positive pole for one-way conduction 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, with a maximum output voltage=input voltage * 0.95-1V
