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 |
|---|---|---|---|---|
| Linear 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. |
R4G/R4GN R4GT |
| 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 linear regulator system. |
R4K-36 R3K-36 R4K-80 RK-80 RK RKT TB REK/REKJ RE PRT REH REM VDD |
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.
