Output power: = input voltage *20A, such as: the maximum power of input 12V*20A=240W input 12V is 240W

Input voltage *20A, such as: input 24V*20A=480W, that is: the maximum power of input 24V is 480W

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

Voltage regulation: adjusting the output "V-ADJ" potentiometer with a slotted screwdriver is plugged in the no-load condition (above marked) turn clockwise, counterclockwise), small capacity due to a large output capacitor, output voltage from high voltage to low voltage when the reaction is slow. The adjustment of the instrument is small.

Current regulation: counter clockwise "A-ADJ" potentiometer is about 30 circles, set the output current to a minimum, connect LED, and clockwise adjust the "A-ADJ" potentiometer to the current you need. For battery charging, the battery is fully discharged, the output received again, adjusting RV2 to the current you need, for charging for the use of a dead battery transfer is allowed because the battery remaining power increasing, the charging current is small.

Do not use short circuit output mode to adjust the current, the circuit structure of the boost module can not be adjusted by short circuit.

Input low battery protection and regulation: low battery protection is mainly aimed at preventing the battery from being discharged when the input power is battery, and the battery voltage is too low to damage the power module and battery. For example, set 12V battery low battery protection. A screwdriver is adjusted with RV1 voltage is connected with a 10V power supply module in the input (clockwise voltage adjustable high voltage protection, counter clockwise until the UVLO lights can be reduced), the protection of low voltage battery is 10V, when the battery voltage drops to 10V power module does not rise (input voltage is equal to the output voltage)

The following points should be paid attention to when using the boost power supply:

1 the voltage of the input power supply must be above 10V.

2 when the switch power is used as the input power supply, the input power supply is well connected to the case of empty load and the voltage is adjusted. And then pick up the load. (it is necessary to ensure that the switching power has been working), or the voltage is adjusted by a load first, and then the switch power is disconnected and then loaded. Switching power supply and power supply module are connected in the case of switching power supply. (because the switch power has a climbing time when it is opened. The chip is not working when the voltage is less than 10V. It is easy to break through the MOS tube.

3 when used in constant current mode, the constant voltage must be guaranteed to 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 a 3.2V LED lamp. This situation is not allowed. At least 4 series of LED lights are connected.
