Product Description
DROK-Micro-LM2596-Buck-Converter-Electric-DCDC-Voltage-Transformer-440V-to-5V12V-3A-Stepdown-Volt-Inverter-Pow
- Non-isolated buck converter, its LM2596 chip and 5A huge-current diode allow high working efficiency, small heating and stable performance.
- 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.
- With over-current and short-circuit protection, more safe to use; 3A max output current.
- Has wide application, DIY a voltage stabilizer, charge your digital devices, as car power supply to charge ipad, phone, etc.
Parameters:
Input voltage : DC 4-40V
Quiescent current : 5mA (not include voltmeter ampmeter)
Output voltage :1.2-38V continuously adjustable (the default output is 5V)
Output current : 3A MAX (Please enhance heat dissipation when > 2A)
Output power = input voltage * 3A
Working temperature: -40 to +85 degrees (please enhance heat dissipation when ambient temperature is too high)
Operating frequency : 150KHz
Conversion efficiency : up to 95%
Overcurrent protection : Yes
Short-circuit protection: Yes
Input reverse polarity protection: No (if necessary , please connect diode in series to the input)
Identify resistance : Tablet PC , ipad, iphone (some phones identify circuit is different, need to be adjusted)
Voltmeter minimum resolution : 0.05V/0.05A (it automatically switch decimal point when in 10V or less)
Output anti-anti- irrigation : Yes (no need for plus blocking diode when charging)
Wiring: has terminals for wiring; 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
Package include:
1x Buck Converter
