BULVACK 20-Pack LM2596 DC to DC High Efficiency Voltage Regulator 3.0-40V to 1.5-35V Buck Converter DIY Power Supply Step-Down Module. Electrical Parameters: Input Voltage: DC 3 -40 V Output Voltage: DC 1.5 - 35 V Output Current: 3A(MAX) It is recommended to use under 2A (NOTE: When using high power, add a heat sink to the power supply chip) Load adjust ratio: +/-0.5% Voltage adjust ratio: +/-2.5% Transferring efficiency: 92% Max(the higher output voltage, the higher efficiency) ON/OFF frequency: 150KHz Output ripple: 200mV Module feature: buck and non-isolated Rectification method: non-synchronous rectification Function: 1.Built in over-temperature protection function 2.Built in current limit function 3.Built in output short-circuit protection function How to use: 1.Access the power supply ( 3 -40 V), the power indicator light, the module is working properly. 2.Adjust the blue potentiometer knob (usually clockwise rotation boost, counterclockwise rotation Step-down) and monitor the output voltage with a multimeter to reach the required voltage. 3.A customer reflects the module output voltage can not be adjusted, always equal to the input voltage. When you encounter this problem, please first counterclockwise rotation potentiometer 10 laps above, and then use the module can be normal adjustment of the voltage. Package includes: 20 X LM2596 board Note: This is a buck module. The input voltage must be higher than the output voltage. The input and output interface can not be reversed. It is recommended to use the current within 2.5A when working for a long time. If it exceeds 2A, you need to add a heat sink (output above 10W).

AITRIP 10PCS 4PCS AC/DC to DC Step Down Buck Converter AC 5-30V DC 5-48V 24V 36V 48V to DC 2.5-35V 12V Voltage Regulator Board 2A Adjustable Volt Power Supply Module. Features 1: A: The power module adopts the plug-in LM2596HV, the high voltage version of the LM2596. The maximum input voltage is 50V (limited by the filter capacitor withstand voltage). The external heat sink can withstand high current operation. The input terminal uses a 4A rectifier bridge stack to input AC power, and has a dedicated DC input port, which is commonly used for AC and DC input. The output voltage can be adjusted from 3.3V to 33V, and the output voltage will vary with different input voltage ranges. B: Input AC voltage AC5V-AC30V or DC5V-50V, due to the large fluctuation of AC voltage, the recommended AC voltage range has reserved margin. The power module has a maximum input voltage of 50V (limited by the filter capacitor withstand voltage) and a heat sink. The output current can work stably at 2.2A output current for a long time, and can work at 3A output current for a short time. The front of the PCB has the name of the silk screen terminal, and the back side also has the name of the silk screen terminal. When soldering the lead, please recognize it and solder it to prevent damage. Futures 2: Input voltage range: AC 5V-30V, DC 5V-50V Output output range: DC 3.3V-33V Output current range: up to 2.2A (the regulator chip can withstand a maximum current of 3A, can work at 3A output current for a short time Module size: 51mm*26mm Package: 10pcs LM2596HV AC/DC to DC Buck Converter Module 3v 3.3V 5V 6V 9V 12V 15V 24V DC 5V-50V Adjustable Step-Down 3A LM2596 Power Supply.
