30W Power Supply Module DC 5~30V to 0.5~30V Automatically Boost/Buck Voltage Regulator DC 5V 12V 24V Adapter/Driver/Charger

Features：

• 1. Automatically Boost or Buck

• For example, no matter what the input voltage is higher than 12V or less than 12V, the voltage can be steadily output 12V.

• If you want to power on 12V for module, the output can buck to 5V, as well as boost to 24V.

• 2. Constant function

• Input any value within 5~30V, can rechargeable storage battery, lithium battery, 5th battery. Besides, it can adjust the brightness of constant current LED.

• 3. No need multimeter can set the current value! The using of one-loop potentiometer with scale is easier!

• 4. Low output ripple voltage：Two-stage filter, suitable for powering to audio amplifiers, analog circuits!

• 5. The factory output voltage defaults 12V, constant current defaults 2A. Please adjust the output voltage and constant current value to prevent load from damage. The higher multitier potentiometer is used for adjusting the output voltage; the shorter one-loop potentiometer is used for adjusting constant current value. If you need to increase voltage /current, please adjust the corresponding potentiometers clockwise, whereas counter-clockwise adjustment.

• 6. Protective function：MOS-input anti reverse protective, under-voltage shutdown protection, output over-current protection.

• 7. Turn lights in full-charge：Red lighted when the module is in constant status. Blue lighted when the module is charging. Green lighted when the charging current is less than one-tenth constant current value you set, in other word, charging is finish.

Import Instructions:

• 1. On the module,  IN+ is the input positive， VO+/VO- are output positive and negative! This module has the function of MOS-input anti reverse circuit. Compare with diode reverse polarity circuits, this reverse function has the advantage of lower loss and higher efficiency.

• 2. In order to make sure the function of automatically boost and buck voltage work steadily, the power of module power supply must bigger than the maximum load power! To avoid the event, which the input voltage falling sharply after loading so that the module cannot work normally. For example, the output power is 20W, the input power must bigger 24W!  

• 3. The factory output voltage defaults 12V, constant current defaults 2A. Please adjust the output voltage and constant current value to prevent load from damage. The higher multitier potentiometer is used for adjusting the output voltage; the shorter one-loop potentiometer is used for adjusting constant current value. If you need to increase voltage /current, please adjust the corresponding potentiometers clockwise, whereas counter-clockwise adjustment.

• 4. The angle of current potentiometer one-loop adjustment is 270 degree, total 10 intervals; every interval current value is equal. Turn to the maximum, the constant current is 4A; Turn to the middle, the constant current is 2A, and so on.

• 5. Turn lights in full-charge. There are green, blue and red lights. Red lighted when the module is in constant status. Blue lighted when the module is charging. Green lighted when the charging current is less than one-tenth constant current value you set, in other word, charging is finish.

• 6. The maximum output value is 4A, but it is limited by the maximum output power, naturally sink is 35W. For example, the output voltage is 15V, the current should not bigger than 2A.(If the sinking is strength, the output power can arrive 50W )

• 7. If you want the module full-load output, the input voltage needs to be over 8V. When the input voltage is 6V, the output power is about 15W.

• 8. Short-circuit protective function. After enter the protection status, the module will close output. Power off and power on again, the module will output normally.

• 9. When used for solar energy to recharge batteries, it is necessary to counter filling in series diodes on the output side, preventing battery voltage reflected power module error will result in a probability of downtime.

Parameters:

• Input voltage: DC 5 ~ 30V  

• Output voltage: DC 0.5 ~ 30V

• Output current: 3A (Long-term stability work); 4A (strength sinking can reach)

• Output power: 30W (naturally sinking); 50W (strength sinking).

• Switch efficiency: Boost voltage 88~91%; Buck voltage 87~90%（It will be changed according to voltage difference and load）

• Working frequency: 180KHZ

• Board size: 68 x 29 x 21mm

Application:

• 1. Very suitable for the device of large input voltage range and constant output voltage, such as constant voltage battery, solar power generation, power module.

• 2. Input a constant voltage (such as mobile phone charger or storage battery charging) can get DC 0.5~30V adjustable power.

Package Include:

• 1 x DC Boost Buck Converter (Power Supply Module)
