Small LED Switching Power Supply Small Power Adapter 4-5V for 500-600mA LED

Constant current source drive do not need in the output circuit series current limiting resistance, LED through the current is not affected by the external supply voltage change, environmental temperature change, as well as LED parameter dispersion, so that the current can maintain constant, full play of various excellent characteristics of LED.

LED constant current power supply is adopted to supply power to LED lamps. Due to the automatic detection and control of the current flowing through LED during the power supply, there is no need to worry about too high current flowing through LED in the moment of power supply, and no need to worry about the load short-circuit burning power supply.

Why UV LED Light Source with Constant Current Drive Power?

Because the constant current source drive, do not need in the output circuit series current limiting resistance, LED through the current is not affected by the external supply voltage change, environmental temperature change, as well as LED parameter dispersion, so that the current can maintain constant, full play of various excellent characteristics of LED.

LED constant current power supply is adopted to supply power to LED lamps. Due to the automatic detection and control of the current flowing through LED during the power supply, there is no need to worry about too high current flowing through LED in the moment of power supply, and no need to worry about the load short-circuit burning power supply.

Cautions for UV LED Light Source Selecting 4-5V Power Source :

The LED lamp with constant current power supply is selected. The price of resistor, capacitor, IC and other components of the LED drive power supply varies greatly. The scheme adopted by the whole power supply and the rationality of the circuit design will directly affect the quality of the product.

Some drive power supply is only constant voltage, not constant current, and LED lamp must be constant current to better ensure the quality and service life. Therefore, extra attention should be paid to this point when purchasing, especially for high-power LED lights. When the LED lamp is working, as the working time increases, the components become hot and resistance decreases. If it is a constant voltage power supply, the current will increase, great instability, affect the life of the lamp. Constant current drive power supply, the current is not changed, which is better for the life and stability of the whole life.

500-600mA Constant Current Switching Power Supply Purpose :

Suitable for various high current surface treatment occasions.
