Input voltage :DC10-60V (Direct input 10-60V without jumper cap selection voltage) (Updated 2016/5/15)

Input current: 20A (MAX) more than 15A, please add fan heat dissipation (fan heat dissipation input voltage at 12-24V input current can reach 25A)

Static working current: 15mA(when 12V to 20V, the higher the output voltage, the static current will increase)

Output voltage: 12-80V continuously adjustable

Output current: 18A MAX exceeds 10A, please strengthen heat dissipation (related to input and output pressure difference, the larger the pressure difference, the smaller the output current)

Constant current range: 0.5-18A (+/-0.3A)

Input anti-reverse connection: Yes (150A power MOS anti-reverse)

Low battery protection: Yes (9-50V adjustable)

Working temperature: -40~+85 degrees (please strengthen heat dissipation when the ambient temperature is too high)

Operating frequency: 150KHz

Conversion efficiency: 92-97% (efficiency is related to input, output voltage, current and pressure difference.

Input overcurrent protection: Yes (input more than 25A, automatic protection, power supply does not boost)

Short circuit protection: there is (input 30A fuse) double short circuit protection, safer use.

Input reverse protection: there is (150A power MOS tube anti-reverse. Can be reversed for a long time)

Installation method: 4 3mm copper columns

Wiring mode: Terminal (please use high current pure copper wire)

Output power: = Input voltage x 20A, for example: Input 12V x 20A=240W Input 12V power is 240W

Input voltage *20A For example, input 24V*20A=480W, that is, the power is 480W when input 24V

Note: Input 12V power is 240W, input 24V power is 480W, input 36V power is 720W

The power supply material is very strong. The input uses 4 63V/470UF high frequency and low resistance electrolytic capacitors, and the output is 3 100V/470UF electrolytic capacitors. The 33MM super power ferrosilica-aluminum magnetic ring is wound with 3 1.2MM pure copper wires to prevent over-temperature magnetic saturation in the case of flow. Use a 116MM*58MM*14MM aluminum radiator to dissipate heat. And the heat sink has a 5015 fan (5MM*5MM*15MM) mounting hole; The output voltage and current of the imported power management chip are continuously adjustable. What's more, the price is not expensive.

Output voltage/output current regulation/Input low battery protection regulation

Voltage regulation: When the power is on and no load is on, use a flat-head screwdriver to adjust the output "V-ADJ" potentiometer (marked in the figure above) to increase clockwise and decrease counterclockwise. Due to the large output capacitance, the output voltage will react slowly when it is adjusted from high voltage to low voltage. The scope of the instrument adjustment is smaller.

Current adjustment: Adjust the "A-ADJ" potentiometer counterclockwise about 30 turns, set the output current to small, connect the LED, adjust the "A-ADJ" potentiometer clockwise to the current you need. For battery charging, after the battery is discharged, then connected to the output, adjust RV2 to the current you need, and be sure to use the discharged battery to adjust when charging, because the more the battery remains in power, the smaller the charging current.

In particular:

Do not adjust the current by short circuit output, and the circuit structure of the booster module cannot be adjusted by short circuit.

Input low battery protection adjustment: The low battery protection is used to prevent battery overdischarge when the input power supply is battery. The low battery voltage damages the power module and battery. For example, set 12V battery low battery protection. Connect a 10V voltage to the input end of the power module and adjust RV1 with a flat-head screwdriver (clockwise protection voltage increases, counterclockwise protection voltage decreases) 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 (input voltage equals output voltage).

The following points should be noted when using the booster power supply:

1 Input power supply voltage must be more than 10V.

2 When the switching power supply is used as the input power supply, connect the input power supply and adjust the voltage without loading. And then you pick up the load. (It must be ensured that the switching power supply is always working), or first adjust the voltage without load, and then disconnect the switching power supply before connecting to the load. When the switching power supply is on, connect the switching power supply and the power module. (Because the switching power supply has a climb time when it is turned on. The chip does not work when the voltage is below 10V. It's easy to break through the MOS tube.

3 When used to set the voltage in constant current mode, ensure that the set voltage must be higher than the input voltage. (For example, the input voltage of the power supply is 12V no-load output voltage is 15V at this time to connect to a 3.2V LED lamp. This situation is not allowed. Less than 4 LED lights connected in series)

Scope of application:

1, DIY a regulated power supply, the input 12V can be, the output can be 12-80V adjustable.

2, power your electronic equipment, you can set the output value according to your system voltage.

3, as a car power supply, for your laptop, PDA or various digital products power supply.

4, DIY a high-power notebook mobile power: equipped with a large-capacity 12V lithium battery pack, so that your notebook can be lit wherever it goes.

5, solar panel voltage regulation.
