Product selling point:

1. Using high-quality materials, the quality is guaranteed

2. Fan blade heat dissipation is adopted, the heat dissipation effect is very good, and the output power is higher

3. The temperature-controlled fan adopts hydraulic bearing fan, which has achieved a good balance in noise and heat dissipation. When the load is light, the fan does not turn. When the load temperature reaches about 60 degrees, the fan automatically rotates. Can effectively reduce noise and prolong service life

4. The main power tube insulation board is made. of high-quality aluminium, and the thermal conductivity is 10 times that of ordinary insulation pads

5. Oversized ferrosilicon aluminum magnetic ring using four 1.2 pure copper enameled wires, calorific value and high efficiency

6. With constant current function, it can be used for car battery boost, battery charging, etc.

Output power: = input voltage *20a, for example:

input 12v*20a=240w the maximum power at input

12V is 240W

Input voltage *20a e.g. input 24v*20a=480w, i.e. the most active power is 480W when input 24V

Note: the maximum power is 240W when 12V is input, 480W when 24V is input, and 720W when 36V is input

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

Voltage regulation: adjust the "v-adj" potentiometer at the output end (marked in the figure below) with a slotted screwdriver when the power is turned on and no-load. Turn it up clockwise and turn it down counterclockwise. Due to the large capacity of the output capacitor, the response will be slow when the output voltage is adjusted from high voltage to low voltage. The adjustment range of Jianyi is smaller. (the default output voltage is adjusted to 19v for shipment.)

Current regulation: adjust the "a-adj" potentiometer counterclockwise for about 30 turns, set the output current to the minimum, connect the LED or current, and adjust the "a-adj" potentiometer clockwise to the current you need.

For battery charging, after the battery is discharged, it is connected to the output and adjusted to the current you need. When it is used for charging, it must be adjusted after the battery is discharged (by default, the output power is adjusted to 3A for shipment. Do not adjust the current by short-circuit output. The circuit structure of the boost module cannot be adjusted by short-circuit,

Input low battery protection regulation: low battery protection is mainly used to prevent the battery from over discharging when the input power supply is battery, and the low battery voltage will damage the power module and battery.

For example, set the low battery protection of 12V battery. Connect a 10V voltage at the input end of the power module and use a slotted screwdriver to adjust rv1 (increase the protection voltage clockwise and decrease the protection voltage counterclockwise) until the UVLO light is on. At this time, the low battery protection voltage is 10V
