New masterpiece, 5A step-down constant voltage constant current module with MPPT function, with solar panels to recharge the battery charging current can lift more than doubled, effectively shorten the charging time, reducing the volume of solar panels. For batteries, rechargeable lithium batteries 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 use of the multimeter. It can be used as high-power LED driver modules.
Module name: 5A step-down constant voltage constant current MPPT
Module Properties: non-isolated step-down module (BUCK)
Input voltage: 6-36V
Output voltage: 1.25-32V continuously adjustable, the default output 5V
1.25-32V fixed output (for volume customers) default shipping adjustable output
MPPT Voltage Range: 6-36V
Output current range: 0.05-5A work long hours in the current recommendations 3A
(Default output current is 3A)
Turn lights output range: 0.01-5A (default turn lamp current of 0.3A) current range will be a little difference because of the part parameter error.
Operating temperature: -40 to + 85 degrees
Operating frequency: 180KHz
Conversion efficiency: up to 95% (efficiency of 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)
Anti-anti-irrigation output protection: no, battery output connected blocking diode must be added, otherwise it will burn module! Remember! (Anti-backfeed diodes are reserved for the position, you need to be able to add their own method see below)
Charging indicator: charging red light, green light when fully charged. Turn lights the way for the current detection. When using solar power panels, solar hour charge current is also very small, less than turn the lamp current, the same will be a 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: Terminal (with shell when wire output) IN is the input, OUT output
Module dimensions: length 60mm wide and 31mm high 22mm (excluding header)
Note: Current detection module for detecting the low-end, please do not put a negative electrode and the negative input of the output directly with a lead!
1, DIY a power supply with a constant current function, not afraid to use during short circuit, can protect the load.
2, the power supply for your electronic devices.
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 is more than doubled. With a constant current, which prevents battery overcharge, effective protection of the battery.
5, driving high-power LED, free to series and parallel combinations,
6, as the vehicle power supply for your cell phone or digital products supply.
Set the voltage, current, and turn lights way :( see figure below)
The module has no output voltage, please set the MPPT potentiometer clockwise adjusted output voltage.
1, set the output voltage: with float voltage according to the value you want to charge the battery, or string, parallel LED voltage value, the constant voltage regulator potentiometer (CV), the output voltage is set to the desired voltage. (Without load connected under)
2. Set the turn lamp current indication: After setting the output voltage, the CC adjustment potentiometer counterclockwise around 20 laps, with a multimeter 20A current file output short circuit, regulator CC potentiometer you need to turn the lamp current, and then turn adjustment light electrical potential, just transferred until the green light.
3, setting the constant current value: improved after adjusting the lamp current, the multimeter 20A current file is still short-circuited output (with voltage, current meter can directly wire shorted output) CC adjustment potentiometer to set the current value you need. (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 you want to set the charging current and accurate, with a completely discharged battery connected to the output and then set the output current.)
Note: When you set the constant voltage higher than 1.25V, otherwise constant function will fail.
4, set the MPPT voltage:
A, adjustable power supply using the method set: the adjustable power supply voltage is adjusted to the set value (eg 18V), the output is not connected to the load at module output voltage, counterclockwise tune MPPT potentiometer to set the output voltage can just reduce the critical point.
B, using the method of direct solar panel set: input directly connected to the solar panels, according to the load with setting the output voltage, shields part of the light shone on the solar panel, then the output load. Multimeter to measure the output voltage of the solar panel (cut with a voltage meter to the input voltage display), adjust the potentiometer to the MPPT solar panel voltage to a maximum power point voltage. (Actual solar panel 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 measuring mode MPPT value, the multimeter string into the current file (with the header 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 the solar panel, so as to align MPPT value.
