Module name: 1200W boost constant current module
Module attribute: non-isolated boost module (BOOST)
Input voltage: 10-60V
Input current: 20A, please add fan for heat dissipation if it exceeds 15A (when the input voltage is 12-24V, the input current can reach 25A)
Static working current: 15mA
Output voltage: 12-83V continuously adjustable (the default output is adjusted to 19V for shipment. If you need to adjust to other voltage values, please specify. If you have a multimeter, the buyer can adjust it yourself)
Output current: 18A MAX, please strengthen heat dissipation if it exceeds 10A (related to the input and output pressure difference, the larger the pressure difference, the smaller the output current)
Constant current range: 0.3-20A
Output power: = input voltage * 10A
Working temperature: -40~+85 degrees
Working frequency: 150KHz
Conversion efficiency: ≤95% (efficiency and input, output voltage,
Current, pressure difference)
Installation method: 4pcs 3mm column
Wiring mode: welding output (please use high-current pure copper wire)
Module size: 130mmx52mmx46mm(LxWxH)
1. Over-current protection: there is a certain error range when the input exceeds 30A,
The output voltage is automatically reduced.
2. Short circuit protection: with (input 40A fuse) double short circuit protection,
It is safer to use.
Pay attention to the following points when using boost power supply:
1 The input power supply voltage must be above 10V.
2 When the power supply is used for the input power, the input power and
The output voltage of the input power supply is first unloaded. Then pick
increase the burden. (It must be ensured that the switching power supply is always working).
3 When using the constant current mode to set the voltage, the constant voltage
Must be higher than the input voltage. Do not use the method of short-circuit output current,
The circuit structure of the boost module cannot be adjusted by short circuit.
Output power:=input voltage*20A, such as: input 12V*20A=240W, the maximum power when inputting 12V is 240W
Input voltage *20A such as: input 24V*20A=480W, that is, when input 24V, the maximum power is 480W
Note: The maximum power is 240W when the input is 12V, the maximum power is 480W when the input is 24V, and the maximum power is 720W when the input is 36V
Output voltage/output current regulation/input low battery protection regulation
Voltage adjustment: Use a flat-blade screwdriver to adjust the output potentiometer (marked in the figure above) when the power is turned on and there is no load. Adjust clockwise to increase and counterclockwise to decrease). Due to the large capacity of the output capacitor, the output voltage is changed from high voltage The response will be slower when the voltage is adjusted to a low voltage. The adjustment range of the instrument is smaller. (The default output voltage is adjusted to 19V for shipment, if we need to adjust other voltage values, please explain or leave a message)
Current adjustment: Adjust the "A-ADJ" potentiometer counterclockwise for about 30 turns, set the output current to the minimum, connect the LED, and adjust the "A-ADJ" potentiometer clockwise to the current you need. For battery charging, after the battery is discharged, connect to the output and adjust RV2 to the current you need. When charging, you must use the discharged battery to adjust it, because the battery has more power , The smaller the charging current. (The default output ESC is 3A for shipment. If we need to adjust the current value, please note or leave a message
Input low battery protection adjustment:
Low battery protection is mainly aimed at preventing battery over-discharge when the input power is a battery, and the battery voltage is too low to damage the power module and battery. For example, set 12V battery low battery protection. Connect a 10V voltage to the input terminal of the power module and use a flat-blade screwdriver to adjust RV1 (clockwise protection voltage value increase, counterclockwise protection voltage decrease) until the UVLO light is on. At this time, the low battery protection voltage is 10V. The power module does not rise when the voltage drops to 10V (the input voltage is equal to the output voltage)
