• 4PCS LM2596HV AC/DC to DC Buck Step Down Converter Module 3v 3.3V 5V 6V 9V 12V 15V 24V DC 5V-50V Adjustable Step-Down 3A Power Supply
• Input ac voltage AC5V~AC30V or dc5v-50v. Due to the large fluctuation of ac voltage, the recommended ac voltage range has been reserved.
• The power module adopts plug-in LM2596HV, LM2596 version of high voltage, the highest input voltage is 50V(limited by filter capacitor voltage) with external radiator, can withstand high current work.
• Input voltage range: AC 5V-30V, DC 5V-50V Output output range: DC 3.3V-33V

• attention: 1. The input voltage should not exceed the maximum input voltage;
• The input voltage: 7V - 20V
• The output voltage: 5V
• High efficiency/high stability/high cost performance MINI560 step-down power module
• High conversion efficiency and low heat generation

• MCU users, if you accept a small load KEY can be connected to the microcontroller about 20s to provide a low level allows the module to continue working. Trigger mode: low level trigger (ground).
• 4 in 1 Charging / Discharging / Lithium Battery Protection / Battery Level Indicator Module. Lithium battery protection function: over-current, overvoltage, over-temperature, short circuit protection.
• The output opens automatically at the first time the load is connected.If the load is less than 50MA, automatically close the output after 30 seconds;If the load is greater than 50MA, the output opens automatically.
• High Power High Efficiency: Discharge efficiency up to 96%. In discharge mode (The charging mode KEY function is invalid), trigger the KEY port once to open the output; continuously trigger the KEY port twice to close the output.
• Can be applied to solar panel turning to mobile phone charging, car charging retrofit, driving recorder power supply, household power supply, intelligent plugging transformation, fast charging adapter, etc.

• Input voltage: 4.2 ~ 40 V
• Adjustable output voltage range: 1.2 ~ 37V
• Output current: 1.5A
• Applications Mobile phone, MP3, MP4, PSP and many other charging equipment
• 12 PCS LM317 Linear Regulator DC Buck Module
