How to control the DC regulated power supply output current constant? Such as constant output around 2a
Power supply can not do, you need is a constant current source.
Constant current produces a constant electric field, but also a constant magnetic field, but the constant electric field and the constant magnetic field field is independent of each other.
Due to the role of constant electric field, the free charge in the conductor to increase the rate of movement; and the process of movement with the conductor
The internal stationary particles collide to decelerate, so that the average rate of free charge does not change with time.
Constant current concept: the size of the direction of the current does not change the time.
Suzhou Greenspan Power is a Sino-US joint venture, long-term based on the cause of industrial power, is set product development, production and sales as one of the high-tech enterprises. The main products are frequency conversion power supply, IF power supply, AC constant current source, DC power supply, UPS, high precision power supply and photovoltaic inverter power supply and other products
1, for the power supply, the output current depends entirely on the load, if the load is stable, the current is stable, if the load changes, the current must change.
2, if the load is constant, and the output current is greater than 2A, you can reduce the current through the series resistance, so that the current constant at around 2A.
3, if the load changes, want to get a stable current, should be used constant current source.
