1. DIY a voltage Regulator, with constant current function, Short-circuit proof, can the load.2. It can supply for electronic devices.3. Charging indicator: charging red, green when fully charged. Turn lamp is the output current detection.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- LED. As a car supply , it can for your cell phone or digital products supply.1. Module Name: 5A constant voltage constant current MPPT2. Module Properties: Non-isolated module ()3. Input voltage: 6-36V4. Output voltage: 1.25-32V continuously adjustable (the default output 5V). MPPT voltage setting range: 6-36V5. Output current range: 0.05-5A (The default output current is 3A)6. Turn lights output range: 0.01-5A (default turn lamp current 0.3A)7. Operating temperature: -40 to + 85 degree8. Operating frequency: 180KHz9. Conversion efficiency: up to 95% (efficiency, input & output voltage, current and pressure-related)10. Over temperature protection: (automatically shut off the output after overtemperature)11. Input reverse polarity protection: None, (if necessary, please add into the diode)12. Output anti-anti-irrigation protection: no, the output must be connected to the battery plus blocking diode, otherwise it will burn the module 13. Installation: 4 pcs 3mm screws14. Connection: IN is the input, OUT is output15.
