DROK Micro CC CV Buck Converter DC-DC Voltage Transformer Step-Down Inverter 4-40V to 5V/12V 3A Power Supply Module Board Constant Current/Voltage with On Board USB LED Volt/Amp Display for Phone
Product Description
DROK Micro CC CV Buck Converter DC-DC Voltage Transformer Step-Down Inverter 4-40V to 5V/12V 3A Power Supply Module Board Constant Current/Voltage with On Board USB LED Volt/Amp Display for Phone
- 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 phone.

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
