100% Brand New and High Quality

 

5A step-down constant voltage constant current module with MPPT function, using solar panels to recharge the battery charging current can improve more than doubled, effectively shorten the charging time, reduce the volume of solar panels. For batteries, lithium batteries, rechargeable, with turn lights control, easy to observe the state of charge. It can be equipped with multi-purpose voltmeter, input voltage, output voltage, output current, output power can be visualized, completely out of multimeter. It can be used as high-power LED driver module.

Module Name: 5A step-down constant current constant voltage MPPT

Module Properties: non-isolated buck module (BUCK)

Input voltage: 6-36V

Output voltage: 1.25-32V continuously adjustable, (the default output 5V, the treasurer For other voltages please explain.)

Output current range: 0.05-5A (default output current is 3A, For other current treasurer please specify)

Turn lights output range: 0.01-5A (default turn lamp current 0.3A, Ask For other current treasurer) current range will be a little difference because parts parameter error.

Working temperature: -40 to + 85 degrees

Operating frequency: 180KHz

Conversion efficiency: up to 95% (efficiency and input and output voltage, current, pressure related)

Short circuit protection: Yes (constant current limit set value)

Overtemperature protection: (automatically shut off the output after overtemperature)

Input reverse polarity protection: None, (if necessary, please enter the string into the diode)

Counter sink output protection: No, when output connected battery blocking diode must be added, otherwise it will burn the module! Remember! (Anti-backfeed diodes are reserved for the position, you need to be able to add their own method, see below) can also be selected ideal diode shop, a smaller loss, higher utilization of solar panels.

Charging indicator: charging red light, green light when fully charged. Turn lights detection mode current. When using solar panels to supply electricity, solar hour charge current is also very small, less than turn the lamp current, it will green light, when it is not full, please note that distinction. Charged with the header will see more direct charging current.
Installation: four 3mm screws

Connection: Terminals (with shell when wire output) IN is the input, OUT output

Module dimensions: length 60mm width 31mm height 22mm (excluding header)

Note: The current detection module is the low-end testing, please do not put negative negative input and output directly with a lead!

1, DIY a power supply with a constant current function, are not afraid to use during short circuit, can protect the load.

2, the power supply for your electronic equipment.

3, for a variety of battery charge, according to different voltage and capacity of the battery charging voltage and charging current is set with charging indicator, easy to observe the state of charge.

4, powered by solar panels for a variety of battery charge with MPPT function, can enhance the charging current than doubled. With a constant current, which prevents battery overcharge, effective protection of the battery.

5, driving high power LED, available free of series and parallel combinations,

6, as the vehicle power supply for your cell phone or digital products supply.

The module has no output voltage, please set the MPPT voltage potentiometer clockwise adjusted output.

1, set the output voltage: with floating voltage according to the value you want to charge the battery, or string, the voltage value LED's in parallel, constant pressure regulator potentiometer (CV), the output voltage is set to the required voltage. (Without connected load case)

2. Set the turn lamp current indication: After setting the output voltage, the CC adjust potentiometer counterclockwise around 20 laps, with a multimeter 20A short circuit output current file, adjust potentiometer CC you need to turn the lamp current, then adjust transfer Light electric potential, just transferred to green light so far.

3, setting the constant current value: improved after adjusting the lamp current, the multimeter 20A current file is still shorted output (with voltage, current meter can directly wire shorted output) CC potentiometer to adjust the current value you want to set. (Short-circuited by the method of setting the output current, the actual charge current is smaller than the short circuit current setting, the battery should have a residual voltage, if the charging current to be set accurately, use completely discharged battery connected to the output and then set the output current.)

Note: Constant setting voltage is higher than 1.25V, otherwise constant function will fail.

4. Set MPPT voltage value:

    A, adjustable power supply using the method set: the adjustable power supply voltage to be set adjusted value (eg 18V), the output is not connected to the load, in the module output voltage, counterclockwise tune MPPT setting potentiometer output voltage to just reduce the critical point can be.

    B, method of solar panels set directly: Enter directly connected to the solar panels, according to the load with setting the output voltage, shielding part of the light shone on the solar panel, the output load connected. Multimeter to measure the solar panel output voltage (cut with a voltmeter to the input voltage display), adjust the potentiometer to MPPT solar panel voltage to a maximum power point voltage. (Solar panels actual maximum power point voltage will be lower than the nominal voltage, such as 18V solar panels, maximum power point will be around 17.5V,)

          You can also adjust the output current by measuring the way MPPT value, the multimeter in series with the current file (with the meter can be switched to the current display) between the output and the load to the callback MPPT potentiometer to the output current to the maximum.

     Note: When using the solar panels directly transferred MPPT value, solar panel power is greater than the load power emitted, please Shu block some of the light shone on the board too, in order to reduce the power of solar panels, so as to align MPPT value.

 MPPT value is adjusted to the maximum power point of solar panel charging current 1.651A, lifting nearly double the charging current, the effect is quite obvious.

The same charging parameters can be reduced the size of the solar panels, the same solar panels, can accelerate the charging speed. This effect, whether factory or individuals, are very useful.
