Output power:=input voltage * 30A, for example: input 12V * 30A=360W, the maximum power at input 12V is 360W

Input voltage * 30A, for example: Input 24V * 30A=720W, that is, the maximum power when inputting 24V is 720W

Power description:

Due to the maximum input current of 30A at 10-30V and 25A at 31-60V, the output power of this power supply is related to the input voltage. The higher the input voltage, the greater the power,

(Input voltage * input current equals the overall power) For example, the input 12V * 30A power is 360W. The input 24V * 30A power is 720W. When the input voltage is 36V, the maximum input current is 25A. The maximum power of the power supply is 900W

Main advantages:

1. The power supply adopts four 1.2MM pure copper wires made of double iron silicon aluminum. 100V/210A low resistance power MOS, high-power and high current input, suitable for high-power LED and motor use

2. Equipped with input MOS anti reverse connection protection, there is no need to worry about the input connection burning out the power supply instead

3. Low battery protection will not damage the power module and battery due to excessive battery discharge when using battery input.

5. Thickened radiator and intelligent temperature controlled fan for heat dissipation.

Voltage regulation:

When the power supply is connected and unloaded, use a flat screwdriver to adjust the output terminal "V-ADJ" potentiometer (as shown in the figure below) clockwise to increase and counterclockwise to decrease. Due to the large output capacitor capacity, the response will be slower when adjusting the output voltage from high voltage to low voltage. The adjustment range of the instrument is smaller. (The default output voltage is adjusted to 19V for shipment. If you need us to adjust other voltage values, please explain or leave a message)

Current regulation:

Turn the "CC A-ADJ" potentiometer counterclockwise for about 30 turns, set the output current to the minimum, connect a load such as an LED battery, and adjust the "CC A-ADJ" potentiometer clockwise to the current you need. For battery charging, after discharging the battery, connect it to the output and adjust CC A-ADJ to the current you need. When charging, be sure to use the discharged battery to adjust it accurately, because the more remaining battery charge, the lower the charging current. The default output power is adjusted to 3A for shipment. If we need to adjust the current value properly, please do not use short-circuit output to adjust the current. The circuit structure of the boost module cannot be adjusted through short-circuit,

Input low battery protection adjustment:

Low battery protection is mainly aimed at preventing battery over discharge when the input power supply is a battery. Low voltage protection should also be set when the battery voltage is too low to damage the power module and when the battery input is a switching power supply

Method 1: For example, set 12V battery low battery protection. Connect a 10V voltage to the input terminal of the power module and use a flat screwdriver to adjust RV1 (increase the clockwise protection voltage value and decrease the counterclockwise protection voltage value) until the UVLO light is on. At this time, the low battery protection voltage is 10V. When the battery voltage drops to 10V, the power module does not rise (the input voltage is equal to the output voltage). Only when the input voltage is higher than 10V, the power automatically recovers and starts boosting.

Method 2: Connect the input battery or switch power supply. If the UVLO light on the board is off, turn the RV1 potentiometer counterclockwise to turn the UVLO light on. After turning it on, turn it clockwise for two more turns. If the UVLO light is on, turn the RV1 potentiometer clockwise to turn off the UVLO light. After turning it off, turn it two more turns. (Suitable for 8V-45V voltage)
