4-40V to 1.2-38V DC to DC converter step-down buck Constant voltage and current power supply Voltage Regulator Battery Charging Description LM2596 4-40V to 1.2-38V DC to DC converter step-down buck Constant voltage and current power supply Voltage Regulator Battery Charging LED Driver with amp volt display and usb output for Charing #1300204 module name : Constant voltage and current buck With voltage and current display Output with USB port With identification resistor 5V to charge the phone directly 3A maximum output current Module Name: LM2596 step-down constant current module with digital display Module Properties: non-isolated step-down module (BUCK) Input voltage: DC 4-40V (limit 40V)Please keep the voltage headroom Quiescent Current: 5mA without voltmeter ammeter Output voltage: DC 1.2-38V continuously adjustable Output Current: 3A MAX,Please enhance heat dissipation exceed 2A (With the input, the output voltage difference,The greater the voltage difference between the output current is smaller) Constant current range :0.1-3A Output power: = Output voltage * 3A Such as: Output 5V * 3A = 15W, 12V * 3A = 36W, 24V * 3A = 72W, Operating temperature: -40 to +85 ° C (ambient temperature is too high, please enhance heat dissipation) Operating Frequency: 150KHz Conversion efficiency: up to 95% (efficiency is related input,output voltage, current, voltage difference ) Current protection: yes (constant current set value) Short circuit protection: Yes (constant current set value) Input Reverse Polarity Protection: None, (if required in the input string into the diode) Output prevent anti-irrigation: none, (if required in the output diode in series)Identification resistor: Tablet PC, pad, phone (some phones identification circuit is different, need to be adjusted) Voltmeter minimum resolution: 0.05V/0.05A (10V following automatic switching decimal point) Installation: four pcs 3mm screws Wiring: no need welding output terminals Module dimensions: length 60mm *width 35mm* height 20mm Applications: 1, DIY a regulated power supply, the output can be 1.2-38V adjustable with voltage and current display 2, the power for your electronic devices, can according to your system set output voltage value. 3, as the vehicle power supply for your laptop, PDA, or a variety of digital products supply. 4, the solar panel regulator. 5, DIY high current mobile power with a single lithium battery can be boosted to 5V, comes with USB port and identification resistor, and a large current of 2.5A output to several phones simultaneously charging. Instructions: 1. voltage meter power supply options: you can choose via jumpers supply voltage meter is provided by the input or output provided (IN is input, OUT is the output ) lower voltage can reduce the loss of the voltmeter, the jump lines jumpered to remove the jumper cap, voltmeter does not work. Two, USB output port: USB interface board is connected directly to the output terminal, and can be directly used to charge the phone, has been identified with resistance to note is that in using the USB output, first determine whether the output voltage with your consistent voltage digital products, remember! ! Otherwise it will burn your digital products. Third, the display voltage and current switching: This module via a band switch to switch the display input voltage and output voltage and output current, Represents the input voltage VI, VO represents the output voltage. Represents the output current IO. Output current adjustment method: 1, regulating CV potentiometer, According to your battery or LED, the output voltage is set to your desired voltage value. Such as 5-string LED voltage regulator 18.5V, bunches tune 8.4V lithium battery and so on. 2, set CC potentiometer counterclockwise around 30 laps, the output current is set to the minimum, Connect the LED, adjust CC China locator to the desired current. For battery charging,After the battery is discharged,And then connected to the output,CC tune to your desired current,(Make sure when you used to charge the battery completely discharged before being allowed to adjust, because the battery is left on, the more power, the charging current is smaller.) Can also be adjusted by way of a short circuit current, short-circuit output current range multimeter 20A CC adjustment potentiometer you need to set the current value. Note: Constant voltage setting higher than 1.25V, otherwise the constant function will fail. packing including: 1x DC to DC converter Payment We only accept payments via paypal.
