welcome to our shop! Description DC-DC 4.5-30V to 0.8-30V adjustable buck step down power supply module Solar lithium battery charging LED Driver with PWM #1300115 5A step-down constant voltage constant current module, For batteries, lithium batteries, charging, With turn lights control, Convenient to observe the state of charge Can be used as high-power LED driver modules, With PWM control input interface And switch control interface, Easy to use microcontroller drive current Module parameters: Module name: 5A constant voltage constant current buck Module Properties: non-isolated step-down module (BUCK) Input voltage: DC4.5-30V Output voltage: DC0.8-30V continuously adjustable (default output 5V, for other voltages,Constant adjustment potentiometer (CV), the output voltage is set to the desired voltage how to use: The leftmost adjustment pot sets the transition point of the indicator LED. 1) Set voltage desired under a load using your DVM. 2) Set current limit with DVM ammeter. 3) Using an adjustable load, drawing maximum current, decrease current gradually until desired float voltage is reached. Set left hand pot adjustment to transition from RED to GREEN. 4) For battery charging applications, this would indicate 'Finished' point. For battery charging, DO NOT exceed battery manufacturer's specifications Output current range :0.1-5A (the default output current of 3A, for other current value,CC potentiometer adjustment ) Output turn lights range :0.1-5A (default transition lamp current of 0.3A, for other current value Turn potentiometer adjustable lamp power (LED ) Current range will be a little difference because of the error part . Operating temperature: -40 to +85 degrees Operating Frequency: 300KHz PWM control frequency range :100-300Hz Conversion efficiency: Up to 95% (efficiency and input and output voltage, current, pressure related) Short circuit protection: Yes (current limit set current value) Over-temperature protection: Yes (over-temperature shutdown automatically after output) Input Reverse Polarity Protection: None, (if required in the input string into the diode) Output protection against anti-irrigation: none, (anti-anti-irrigation diodes are reserved position, you need to be able to add their own. Methods see below) Charging indicator: charging red light, green light when fully charged. Turn lights detection method for the current. Installation: four 3mm screws Connection: Terminal (with shell when the output wire) V-IN as an input, V-OUT is the output Module dimensions: length 60mm width 26mm height 20mm Module current is detected as the low-end testing, please do not put the negative input and output negative directly with a lead! Applications: 1, DIY a regulated power supply with constant current function, are not afraid of using the process will be short, you can to protect the load. 2, the power for your electronic devices. 3, for a variety of battery charging, According to different voltage and capacity of the battery charging voltage and charging current is set with charging indicator function to facilitate the observation of the state of charge. 4, powered by solar panels for a variety of battery charging with constant current, which prevents battery overcharge, effective protection of the battery. 5, the drive power LED, can be freely series and parallel combinations with PWM control input, the available single-chip control LED brightness (PWM control frequency range 100-300Hz). 6, as the vehicle power supply for your mobile phone or digital products supply. Set the voltage, current, and turn lights approach: (see diagram above illustrates) 1, set the output voltage: According to you charged battery float voltage value, or in series, in parallel LED voltage value of the potentiometer constant voltage regulator (CV), the output voltage is set to the desired voltage. (No load case) 2, set the switch lamp current indication: After setting the output voltage, the CC adjustment potentiometer counterclockwise around 20 laps, with a multimeter 20A short circuit output current range, adjust the potentiometer to the CC you need to turn the lamp current, then adjust switch light electric potentiometer (LED), transferred just green light so far. 3, set the constant current value: tune improved lamp current, the meter is still short-circuit output current range 20A CC potentiometer to adjust you need to set the current value. Note: Constant voltage setting higher than 0.8V, otherwise the constant function will fail. packing including: 1xbuck step down power supply module Payment We only accept payments via paypal.
