1200W DC-DC CC CV high-power step up module solar charging 12-80V 20A

    Module name: 1200 W boost constant current module  

    Module nature: non-isolated boost module (BOOST)

    Input voltage: 8-60V

    Input current: 20A 

    Static operating current: 15mA (When the output voltage is increased from 12V to 20V, the higher the output voltage, the higher the static current will be)

    Output voltage: 12-80V continuously adjustable

                      12-80V adjustable

    Output current: 20 A MAX. If it exceeds 18A, please increase heat dissipation (related to the input and output voltage difference. The greater the voltage difference, the smaller the output current)

   Constant current range: .Maximum 20A

   Output power: = input voltage * 20A, such as: input 12V * 20A = 240W, input 24V * 20A = 480W,

                    Input 36V*10A=720W, Input 48V*20A=960W, Input 60V*20A=1200W

                    If you need more power, you can use two modules in parallel. For example, if the output is 30A, you can use two modules in parallel.

                    Just adjust the current of each module to 15A.

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

    Operating frequency: 150KHz

    Conversion efficiency: .Up to 95% (efficiency is related to input and output voltage, current and voltage difference)

    Overcurrent protection: Yes (with current limiting function, current regulation, adjustable output current limit, current exceeds the current limit value, automatically reduce the output current to a minimum of 5A, the current will vary depending on the nature of the load.)   

    Short circuit protection: Yes (input 20A fuse)   double short circuit protection, safer to use.

    Input reverse connection protection: None (please connect a diode in series with the input if necessary)

    Output anti-reverse charging: Yes, no need to add anti-reverse diode when used for charging.

    Installation method: 4 3mm screws

    Wiring method: terminal block without welding output

    Module size: 85mm long, 63mm wide, 64mm high

Applications:

1. DIY a voltage-stabilized power supply with a 12V input and an adjustable output of 12-80V.

2. Power your electronic devices and set the output value according to your system voltage.

3. As a car power supply, it can power your laptop, PDA or various digital products.

4. DIY a high-power laptop mobile power supply: equipped with a large-capacity 12V lithium battery pack, your laptop can be powered wherever you go.

5. Solar panel voltage stabilization.

6. Charge storage batteries, lithium batteries, etc.

7. Drive high-power LED lights.

Instructions:

1. Input voltage range selection: Factory default is 12-60V input

2. Output voltage and current adjustment method:

     1. Adjust the output voltage: adjust the CV potentiometer to set the output voltage to the voltage value you need according to your battery or LED. For example, adjust the voltage of 10 strings of LEDs to 37V, and adjust the voltage of four strings of batteries to 55V, etc.

      2. Adjust the output current: Set the CC potentiometer counterclockwise for about 30 turns, set the output current to minimum, connect the LED, and adjust the CC potentiometer to the current you need. For battery charging, discharge the battery, connect it to the output, and adjust CC to the current you need. (When used for charging, you must use a discharged battery to adjust it accurately, because the more power left in the battery, the smaller the charging current.) Please do not use a short circuit to adjust the current. The circuit structure of the boost module cannot be adjusted by a short circuit.

      3. Overcurrent regulation: Designed for output short-circuit protection, it means that when the output short circuit exceeds the set short-circuit limit current, the power supply shuts down the output to a minimum value of 5A, which varies according to the load, thereby protecting the power module and electrical equipment from damage. Adjustment method: First set the current of the protection point, if it is 8A, it will be protected. Use the output current adjustment method to adjust the output current to 8A, and then adjust the "overcurrent adjustment" CL potentiometer (counterclockwise rotation) to turn the output current suddenly drops to a minimum value. The overcurrent point at this time is 8A. (Note that if the current at the protection point is lower than the current required by the device, the power supply will be protected. If overcurrent protection is not required, it is recommended to turn clockwise about 30 times to adjust it to a maximum value.

     3. Imported 27mm large iron silicon aluminum magnetic ring, thickened copper enameled wire double wire winding, thickened aluminum heat sink, so that the whole module heats up lower, input two 470uF/100V electrolytic capacitors, output three 470uF/100V low resistance electrolytic capacitors, and lower output ripple. The vertical inductor design is more stable, with less interference, replaceable fuse, and double protection is more reliable. The overall setting is very reasonable and the structural design is very sophisticated.
