Description
Constant Current Voltage DC-DC 5A Step Down Module Buck Converter Power Supply Board PWM Mppt Solar Charger Inverter
Product Description
The newly upgraded 5A step-down constant voltage and constant current module can charge batteries, lithium batteries, etc., with turn light control, which is convenient to observe the charging status. It can be used as a high-power LED drive module, with PWM control input interface and switch control interface, which is convenient for using single-chip microcomputer to control the drive current. The new upgrade, the correction of the constant current regulation circuit, makes the whole current regulation process very stable. Let the module work at a lower and more stable temperature for a long time with high current. The input adds TVS diode to make the module more stable. Two 470uF/35V switching power supply dedicated high-frequency low-resistance capacitors, lower output ripple, 13mm large magnetic ring 0.7mm all copper enameled wire. Onboard constant current/charging/full LED work indicator, more intuitive when working. PWM input and switch control interface are reserved. Switches or microcontrollers can be used to control the output and adjust the current through PWM. Four 3mm screw holes facilitate your installation.

Features
Module nature: non-isolated step-down module Input voltage: 4.5V～30V Output voltage: 0.8V ~ 30V continuously adjustable, 0.8V ~ 30v fixed output default delivery is adjustable output Output constant current range: 0.1A～~5A (default output constant current is 3A) Output turn light range: 0.1A～5A (default turn light current is 0.3A) The current range will have a little error due to the difference of parts parameters Working temperature: -40℃～+85℃ Working frequency: 3000KHz PWM control frequency range: 100Hz～300Hz Conversion efficiency: 95% higher (efficiency is related to input, output voltage, current, voltage difference) Short circuit protection: yes (limit current is set constant current value) over temperature protection: yes (automatically shut off output after over temperature) Input reverse connection protection: no (if necessary, please connect a diode in series with the input ) Output anti-backflow protection: none (the position of the anti-backflow diode is hesitant, and you can add it yourself if you need to. See the instructions below for the method) Charging indicator: red light when charging, green light when fully charged. Turning light detection method is current Installation method: 4 3mm screws Wiring method: terminal (when equipped with shell, it is welding wire output) V-IN is input, V-OUT is output Module size: 60mm*25mm The current detection of the module is low-end detection, please do not directly short-circuit the negative pole of the input and the negative pole of the output with a wire!
