Constant Voltage Power Supplies & Constant current power supply

Constant voltage power adapter is more common than constant current power supply in our daily life, for example, the power supply of cell phones, laptops, tablets and these electronic devices is a constant voltage power supply, which has a fixed output voltage value that does not change with the load, the input voltage and other external operating conditions. Constant current power supply is generally used in LED lights, its output current is fixed, not with external factors and change. Eahunt will give specific examples to illustrate the following.

Constant Voltage Power Supplies

For example, a 24/2A power adapter, its fixed output voltage of 24V, but its output current can be changed from 0A to 2A, but once the output current exceeds 2A, its internal circuitry will open the overcurrent protection state, the power adapter stops working. This is a constant voltage power supply.

Constant current power supply

Or take 24/2A power adapter distance, if it is a constant current power supply, its fixed current is 2A, the voltage changes from 0V (short circuit) to 24V, its current will not change, is still 2A, but such as over-voltage exceeds 24V, its internal circuitry will be opened to over-voltage protection state. The power adapter stops working, which is a constant current power supply.

Therefore, this is the reason that the regular power adapter has overcurrent, overvoltage, short-circuit and other eight circuit protection.Eahunt power supply manufacturers, its power supply product categories, a variety of safety certification complete, factory direct sales, support for customization.
