Module Name: 5A buck constant voltage constant current MPPT 
Module Properties: Non-isolated buck module (BUCK) 
Input voltage: 6-36V 
Output voltage: 
1.25-32V continuously adjustable (the default output 5V) 
MPPT voltage setting range: 6-36V 
Output current range: 0.05-5A (The default output current is 3A) 
Turn lights output range: 0.01-5A (default turn lamp current 0.3A) the current range will be a little difference because the parts parameter error. 
Multifunction double display: input voltage, output voltage, output current, output power 
Operating temperature: -40 to + 85 degree 
Operating frequency: 180KHz 
Conversion efficiency: up to 95% (efficiency, input & output voltage, current and pressure-related) 
Short circuit protection: Yes 
Over temperature protection: (automatically shut off the output after overtemperature) 
Input reverse polarity protection: None, (if necessary, please add the string into the diode) 
Output anti-anti-irrigation protection: no, the output must be connected to the battery plus blocking diode, otherwise it will burn the module! 
Charging indicator: charging red, bright green when fully charged. Turn lamp is the output current detection. 
Installation: 4 pcs 3mm screws 
Connection: IN is the input, OUT is output 
Module dimensions:60 x 31 x 22 mm(without meter) 

Note:

Detection module, please do not direct connect the output of negative electrode and the input of negative electrode 

Applications:
1, DIY a voltage Regulator, with constant current function, Short-circuit proof, can protect the load.
2, It can power supply for electronic devices.
3, For a variety of battery charge, can observe the state of charge.
4, charger for all kinds of batteries, with MPPT function, can enhance the charging current to double. With a constant current and prevents battery overcharge, effective protection of the battery.
5, it can support high-power LED.
6, As a car power supply , it can for your cell phone or digital products supply.
