High-power DC adjustable 24V/12V to 5V step-down module, constant current constant voltage 3V6V step-down power chip
1. With crystal case, safe, practical, convenient and beautiful.
2. On-board voltage, current and power meter, you can easily use this module without a multimeter, which is simpler and more intuitive.
3. Onboard USB interface for easy charging of your digital products. (Note: The USB output voltage is the same as the module output voltage. It is not a fixed 5V output. Please confirm before charging the USB device.)
4. High power, high efficiency, 5A, low ripple;
5. Three major functions:
(1) Used as a normal step-down module with overcurrent protection capability;
(2) It is used as a charger for various voltage value lithium batteries, batteries, nickel-cadmium nickel-hydrogen batteries (battery packs), and used in solar panels, wind turbines, etc.;
(3) used as a high power LED constant current driving module;
6. There are two modes of constant voltage and constant current, and there are indicators to indicate which mode the module is currently in;
7. When used as a lithium battery charger, you can set the float voltage and charge current.
Is it charging or already full;
8. With current limiting protection, the module will not burn out even if the output is shorted.
9. The onboard voltage and ammeter can be self-calibrated without any inaccuracy!
Input voltage: 5-36V Reminder: For the onboard voltmeter to be effective, the minimum input voltage is required to be 6.5V or higher.
Output voltage: 1.25-32V continuously adjustable (can only be used as a buck module, the input must be greater than the output 2V or more)
Output current: adjustable, maximum 5A (recommended for use within 4.5A, constant current requires output voltage 2V or more to adjust, current regulation, only works in constant current state, if used to flush the phone, not How much is the current adjustment, how much is the mobile phone, the constant current is mainly used to charge the current limit of the low internal resistance battery or the LED current limit.)
Output power: up to 75W (recommended to use within 50W, please reduce power when using large differential pressure)
Working temperature: -40~+85 degrees Celsius
Working frequency: 180KHz
Conversion efficiency: up to 96%
Short circuit protection: Yes
Over temperature protection: Yes (automatically turn off the output after over temperature)
Input reverse connection protection: None, (If necessary, please input a large current diode in the input string)
Installation method: 4 3mm silk
Wiring method: terminal block or soldering terminal, V-IN is input, V-OUT is output
Module size: length 68.2mm width 38.8mm height 15mm
