I want to buy a power supply. Does anyone have any recommendations? [Copy link]

 

I feel that the power supply in the company is not enough, so I am going to buy a power supply recently. My initial ideal is to buy a programmable linear regulated DC power supply with output short circuit, overvoltage and overcurrent protection. The most commonly used one is 3.6V, the maximum current is basically no more than 1A, and the minimum current can be several microamperes.

Does anyone have any suitable recommendations?

The power is not high, you can try DIY one

The power is not big, and it is linear. It is not too bad for daily experiments. Just buy it.

Just go to Huaqiangbei or Taobao and you’ll find everything.

It is probably an adjustable 0-5V 0-2A input power supply.

I want to buy a ready-made one, use it first, and then DIY it when I have time. I am so busy now. I don’t have time to do it.

There is a radio frequency part on the board, I don't know if there are any requirements.

Well, I saw a 1800 RMB power supply on Taobao, it seems to be made by Guwei. I don't know how it is.

It would be best if it can reach 24V, but 12V is also OK. The requirements are stability, small internal resistance, and the best is to be able to display the output current (microampere level), and the most ideal is to be able to measure the output power (I don’t know if my requirements are too much). Within 1A is enough. Make it low power, the power will not be very large.

Whether your demands are excessive or not depends on whether you have enough money to spend.

If you have enough money, you can shop online or go to the electronics market. Although you need to run around, there are many varieties and it is convenient to choose from. If you have less money, you can make one yourself, which is a good way to gain experience, but it is too troublesome.
