DROK® LM2596 DC Buck Voltage Regulator 36V to 24V 12V 5V 3.3V 3V Converters Constant Volt&Amp 5-36V to 1.25-32V 5A 75W Step-down LED Driver Switch Power Supply Digital LED Voltmeter USB Output

Product Description
 

Buck power converter showing power, voltage and current with USB output connector(charger for digital devices),With short-circuit and over-temperature protection; output automatically shut off if overtemperature,Two working modes of constant voltage and constant current; has red LED indicator for mode notification,Set float voltage and charging current when working as battery charger; Blue LED indicator for charging statue notification,Press one button next to meter for switching among five modes; press another to turn on/off LED display

• Non-isolated constant current and voltage buck converter, please note when setting constant current, the voltage should be higher than 1.25V.
• Has high working efficiency, small heating and stable performance; With over-current and short-circuit protection, hence safe to use.
• With digital display, press the switch to display input volt(VI), output volt(VO) or output current(IO); and the power supply can be set as input(IN) or output(OUT) voltage by jumper.
• The output is with USB interface and identification resistor, can be a 5V charger for mobile phone, please make sure the output is 5V before charging.
• Has wide application, DIY a voltage stabilizer, charge your digital devices, as car power supply to charge ipad, phone.

Additional Information

Input voltage: 4 to 40V(40V extreme)

Identification resistor: ipad, iphone, Tablet PCs 
Min resolution of voltmeter: 0.05V/0.05A(automatically switch decimal point when < 10V) 
Wiring: it has wiring terminals and requires no welding 

Instructions: 
1.Voltmeter power options : you can select power the voltmeter from Input or Output by jumper on the board; you can short the jumper to reduce the loss of the voltmeter. Remove the the jumper cap, the voltmeter does not work. 
2.USB output port: USB interface is connected to the output directly, with the identify resistor. Please make sure the USB output voltage is consistent with the voltage of your products. Otherwise it will burn your digital products. 
3.Switch to display the voltage : VI: input voltage; VO: output voltage 

Please note: 
This DC converter is single output, the output voltage of the USB port is the same as the output voltage of the module, if your load is USB device, please make sure the module's output voltage is set at 5V. 
When setting constant current, the voltage should be higher than 1.25V. 

Package include: 
1x CC CV Buck Converter
