Programmable DC power supplies employ two primary control methods to ensure a stable output: linear and switching regulation.
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. | Low output ripple and noise Fast transient response |
Poor efficiency. Large and heavy. |
R4GT
R4G/R4GN |
| Switching power supply | Input is switched on and off to create high frequency, which is then rectified, controlled, and stabilized. | High power conversion efficiency Compact and lightweight design Wide range of input voltage |
Higher output ripple and noise compared to linear power supplies. |

Linear Regulator Power Supply Typical Applications
Application examples that take advantage of the low noise and high-speed transient response characteristics of the linear regulators:
- Noise-sensitive analog circuits
- Semiconductor characterization
- Testing operational amplifiers (Op-amps) and AD/DA converters
- Powering precision medical and scientific instruments
Switching Power Supply Typical Applications
Application examples that take advantage of the small size and high efficiency of switching regulators:
- High-power applications requiring high efficiency, such as servers and industrial equipment
- Battery charging and simulation
- Automotive component testing (e.g., ECU, motors)
- General-purpose R&D and production testing
Constant Voltage (CV) and Constant Current (CC)
Programmable DC power supplies primarily operate in two modes: Constant Voltage (CV), which maintains a stable output voltage regardless of load variations, and Constant Current (CC), which provides a stable output current as the load changes.
Understanding these modes is essential for selecting the right power supply for your needs.
