6 Frequently Asked Questions about “How to change the output current of the base station power supply”
How do you set a power supply output?
Set each power supply output independently so that the voltages or current sum to the total desired value. For higher voltage, first set each output to the maximum desired current limit the load can safely handle. Then, equally distribute the total desired voltage to each power supply output.
How does a power supply work?
The voltage is regulated, keeping the value constant, with the current being determined by the load. If the load current is high and the load is trying to draw MORE current than the current setting, the power supply will limit the current at the current setting value and operate in CC mode.
How do you connect a power supply?
For higher voltage, connect power supply outputs in series, and for higher current, connect outputs in parallel. Set each power supply output independently so that the voltages or current sum to the total desired value. For higher voltage, first set each output to the maximum desired current limit the load can safely handle.
What happens if a power supply draws current less than 1 a?
When the load connected draws current less than 1 A, the power supply will maintain voltage control in CV mode. If the load draws current at 1 A, the supply will automatically switch to CC mode. In these cases, the current will output at 1 A or at the current limit, while the voltage will decrease down to a value that's dependent on the load.
How do you set a power supply to a high voltage?
For higher voltage, first set each output to the maximum desired current limit the load can safely handle. Then, equally distribute the total desired voltage to each power supply output. For example, if you are using three outputs, set each to one third the total desired voltage.
How does a power supply maintain voltage control in CV mode?
For example, suppose the power supply is set to 5 V and current limit is set to 1 A. When the load connected draws current less than 1 A, the power supply will maintain voltage control in CV mode.
