5A Buck Constant Voltage Constant Current MPPT Module Properties: Non-isolated buck module (BUCK) Input voltage: 6~36 V; Output voltage:1.25~32 V continuously adjustable (the default output 5V); MPPT voltage setting range: 6~36 V. 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) Conversion efficiency: up to 95% (efficiency, input & output voltage, current and pressure-related) Color: Blue Material: plastic Operating temperature: -40~ + 85 degree Operating frequency: 180 KHz Short circuit protection: Yes Over temperature protection: Yes (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: None, the output must be connected to the battery plus blocking diode, otherwise it will burn the module. Installation: 4 Pcs 3mm screws Connection: IN is the input, OUT is output Multifunction double display: input voltage, output voltage, output current, output power Charging indicator: charging red, bright green when fully charged. Turn lamp is the output current detection. Module dimensions:60 x 31 x 22 mm (without meter) Applications: 1. It can support high-power LED. 2. It can power supply for electronic devices. 3. For a variety of battery charge, can observe the state of charge. 4. As a car power supply , it can for your cell phone or digital products supply. 5. DIY a voltage Regulator, with constant current function, Short-circuit proof, can protect the load. 6. 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. Package Included: 1 x Step-down Module Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/-1-3cm.
