CIJIAOPOYU 3V 4A 5A Regulated Switching Power Supply Driver 12W 15W DC transformer AC 100-240V Input AC-DC(5A 15W)

1, (small power consumption) switching power supply adjustment tube is working in the switching state, so the adjustment tube power consumption is very small. 2、（Safe and reliable）Switching power supply can be conveniently designed to automatically protect the circuit. When the circuit failure or short-circuit, can automatically cut off the power supply to prevent the scope of the failure to expand. 3. (High stability) Small power consumption makes the temperature rise within the electronic equipment is also low, reducing the high temperature damage rate of the surrounding components, so that the thermal stability and reliability of the equipment is greatly improved. 4. (Wide voltage regulating range) Switching power supply AC input voltage can achieve good voltage regulating effect when it changes within the range. 5、（Small volume）Switching power supply can directly rectify the input AC voltage from the power grid, and then obtain various different AC voltages through high frequency transformer, eliminating the bulky industrial frequency transformer, so that the weight of the power supply is greatly reduced.
