What is DC power supply? (Basic Knowledge)

The following control methods are used for programmable DC power supplies in order to obtain stable voltage and current.

Control Methods

Type Features Advantages Disadvantages Product series
Switching power supply Input is switched on and off to create high frequency, which is then rectified, controlled, and stabilized. Good efficiency.
Small and lightweight.
Wide range of input voltage.
Lots of noise compared to a series regulator system. R4K-36
R4K-80
RK-80

Series regulator power supply Stabilization is achieved by placing a control circuit between the input and output. Very little noise.
Fast response speed.
Poor efficiency.
Large and heavy.

R4GT

Programmable DC power supplies can be largely divided into two categories: Constant-voltage DC power supplies that have a stable output voltage even when the load changes, and constant-current DC power supplies that have a stable output current.

Constant voltage is also referred to as CV, while constant current is referred to as CC.
