Constant current Adapter different constant voltage adapter

The difference between a constant current power supply and a constant voltage power supply adapter:

When constant voltage power supply is the power adapter in the rated output current range, which is in the scope of work. The output voltage will remain within + / - 5% rated voltage. When the output current is more than 1.3 2 times rated current, power adapter will protect stop working, and when removing the load power can resume normal work. Constant voltage power supply and regulated power supply, the required output voltage value is fixed, not with load, the external working conditions, such as the input voltage changes. The maximum output current of the power, the maximum output power, efficiency, output voltage stability, drift, ripple coefficient of electromagnetic compatibility EMC characteristic, temperature effect,Noise, impedance characteristics and so on have specific requirements.
Constant current power supply, also known as current regulator, less as far as we know, the grasp of the concept of relatively difficult. The output characteristic curve of constant current power supply with constant voltage power supply. The opposite of controlled parameter is the output current, the dependent variable as the compliance voltage. Output current is kept constant in the range of load, load resistance is big, the power supply into compliance pressure limiting reserve, constant current power supply considered overpressure situation. Generally think this area is a protected area, in the area of the output voltage is not clearly. Our term to describe the constant current power supply is used in the constant voltage power supply in familiar. For variable constant current power supply, can adjust the output current, usually fromTo a maximum value near zero (constant current for short range). In order to maintain a constant load current, voltage of the output must follow the load resistance changes. In the output current constant voltage range is called a "compliance voltage. A maximum of the compliance voltage is usually clear. Constant current power supply applications has limitations. Generally used to changes in load resistance is limited within the scope of the occasion of must maintain a constant current. The typical examples such as the LED driver, electron microscopy and gas spectrum apparatus of deflection and winding.
