1Pcs 1200W DC-DC boost constant current vehicle charging power supply module

Description: 1200W High Power DC-DC Boost Constant Voltage Constant Current Adjustable Vehicle Charging Power Supply Module Compared with the old model, the circuit structure is optimized, which makes the power supply work more stably. at the same time increaseinput anti-reverse connection(With 150A MOS anti-reverse) andInput low battery (low voltage) protection, and the low battery protection voltage can be adjusted from 9-50V to adapt to various batteries. When using battery power supply, don't worry about the power module and battery damage when the battery loses power.。 Power description: Since the input current of this power supply is up to 20A, the output power is related to the input voltage. input voltagehigherThe higher the power, for example, the input 12V * 20A power is 240W. The input 24V * 20A is 480W. This is the maximum power. Due to the limited heat dissipation area, when the input voltage exceeds 10A or the output current reaches 10, please add a 12V fan to dissipate heat.

(Input exceeds 25A, automatic protection, power supply does not boost) Short circuit protection:Yes (input 30A fuse) Double short circuit protection makes it safer to use. Input reverse connection protection:Yes (150A power MOS transistor anti-reverse.It can be reversed for a long time.） Installation method:43Mm copper pillar Wiring method:terminal block(Please use high current pure copper wire) Module size:Length 130mm Width 52mm Height 53mm Module weight：300 g Output power:= Input voltage * 20A, for example: Input 12V * 20A=240W, the maximum power when inputting 12V is 240W Input voltage * 20A, for example: Input 24V * 20A=480W, that is, when inputting 24V, the maximum power is 480W Note: The maximum power when entering 12V is 240W, the maximum power when entering 24V is 480W, and the maximum power when entering 36V is 720W. The power supply material is very fierce. The input adopts 4 63V/470UF high-frequency and low-resistance electrolytic capacitors, and the output is 3 100V/470UF electrolytic capacitors. The 33MM super-power ferrosilicon aluminum magnetic ring is wound in parallel with 3 1.2MM pure copper wires to prevent over-temperature magnetic saturation under large current conditions. Use a 116MM * 58MM * 14MM aluminum radiator to dissipate heat. And the heat sink has a 5015 fan (5MM * 5MM * 15MM) installation hole; the output voltage and current of the imported power management chip are continuously adjustable. Output Voltage/Output Current Regulation/Input Low Battery Protection Regulation Voltage regulation:When the power supply is turned on and no load, use a one-word screwdriver to adjust the output terminal "V-ADJ" potentiometer (marked in the picture above) to increase clockwise and decrease counterclockwise). Due to the large output capacitor capacity, the response will be slower when the output voltage is adjusted from high voltage to low voltage. The adjustment range of the instrument is smaller. (The default output voltage is adjusted to 19V for shipment. If you need us to adjust other voltage values, please explain or leave a message) Current regulation:inverseAdjust the "A-ADJ" potentiometer about 30 times an hour, set the output current to a minimum, connect the LED, and adjust the "A-ADJ" potentiometer clockwise to the current you need. For battery charging, after discharging the battery, connect it to the output and adjust the RV2 to the current you need. When charging, be sure to adjust it with the discharged battery, because the more power left in the battery, the smaller the charging current.(The default output is electrically adjusted to 3A for shipment. If you need us to adjust the current value, please leave a message or instructions. In particular, it is noted that: Do not use short-circuit output to adjust the current. The circuit structure of the boost module cannot be adjusted by short-circuit. Enter the low battery protection adjustment:Low battery protection is mainly aimed at preventing battery over-discharge when the input power supply is battery, and damage to the power module and battery if the battery voltage is too low. For example, set 12V battery low battery protection. Connect a 10V voltage to the input of the power moduleAdjust RV1 with a one-word screwdriver (turn up the protection voltage clockwise, turn down the protection voltage counterclockwise) until the UVLO light is on. At this time, the low battery protection voltage is 10V, and the power module does not rise when the battery voltage drops to 10V (the input voltage is equal to the output voltage). When using a boost power supply, the following points should be noted: The voltage of the input power supply must be above 10V. 2 When using the switching power supply as the input power supply, connect the input power supply and adjust the voltage at no load first. Then connect the load. (Must ensure that the switching power supply is always working), or adjust the voltage at no load first, and then disconnect the switching power supply and then connect the load. Connect the switching power supply and power supply module when the switching power supply is turned on. (Because the switching power supply has a climb time when it is turned on. When the voltage is lower than 10V, the chip is not working yet. It is easy to break down the MOS transistor. 3 When using constant voltage in constant current mode, ensure that the constant voltage must be higher than the input voltage. (For example, if the input voltage of the power supply is 12V and the output voltage is 15V, connect a 3.2V LED lamp. This situation is not allowed. At least 4 LED lamps connected in series must be connected) Scope of application: 1. DIY a regulated power supply, the input can be 12V, and the output can be adjusted by 12-80V. 2. To power your electronic devices, you can 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 notebook mobile power supply: with a large-capacity 12V lithium battery pack, your laptop can light up wherever it goes. 5. Solar panel voltage regulation. 6. Charge batteries, lithium batteries, etc. 7. Drive high-power LED lamps.
