DROK step up converter input voltage range is DC 3-32V, 3-10v can be used for low input voltage application, 6-32v can be used for high input voltage application, can be selected by the jumper on the board.This boost module continuously adjustable output voltage is DC 3-35V, default 19V; max output current is 6A, has high efficiency and little heat, low ripple and stable performance.
Application: diy a stabilized power supply, charge your electronic devices, output with usb interface and identification resistor, a single lithium battery can be boosted to 5V to charge your phone; stabilize voltage for solar panel and etc.
The step-up transformer is with digital LED display, it can show input or output voltage, vi: input voltage; vo: output voltage.
The power supply board has over current protection and short circuit protection(input 15A fuse), safe to use.
Description
Parameters:
Module Properties: Non-isolated Boost Module
Input Voltage: DC 3-10V (low input voltage application); 6-32V(high input voltage application), can be selected by the jumper
Output Voltage: DC 3-35V(Continuously adjustable, defualt 19V)
Input Current: max 10A(need heat dissipation when input current is over 6A)
Output Current: max 6A(need heat dissipation when output current is over 5A)
Quiescent Current : 15mA, not include the current of voltmeter
Working Temperature: -40~+85 degrees
Operating Frequency : 280KHz
Conversion Efficiency : up to 96%
Protections: over current protection(when input exceeds 12A, automatically reduces the output voltage) short-circuit Protection(input 15A fuse, double circuit protection) no input reverse polarity protection, if necessary, please connect diode with input in series.
Identify Resistance : Tablet PC, iPad, iPhone (some phones identify circuit is different, need to be adjusted)
Voltmeter minimum resolution : 0.05V(10V or less automatically switch the decimal point)
Instructions:
1. Voltmeter power options : Select power the voltmeter from input or output by jumper on the board, short the jumper to reduce the loss of the voltmeter. Remove 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.
