Programmable DC power supplies primarily use two control methods to regulate output: linear regulation and switching regulation. Choosing the right method depends on your specific requirements for noise performance, efficiency, and size.
Control Methods Comparison
| Type | Operating Principle | Advantages | Disadvantages | Key Series |
|---|---|---|---|---|
| Linear Regulator (Series Regulator) |
Regulates output using a linear control element (transistor) to drop excess voltage. Acts as a variable resistor. |
|
|
R4GT, R4G/R4GN |
| Switching Regulator (Switch Mode) |
Rapidly switches the input voltage on and off at high frequencies, then filters it to generate a stable output. |

Typical Applications: Linear Regulators
Linear models are ideal for applications requiring ultra-low noise and high-speed transient response:
- Powering noise-sensitive analog circuits and sensors
- Semiconductor characterization and testing
- Evaluating operational amplifiers (Op-amps) and AD/DA converters
- Precision medical equipment and scientific instrumentation
Typical Applications: Switching Regulators
Switching models are optimized for high power density, efficiency, and general-purpose use:
- High-power industrial equipment and server testing
- Battery charging, discharging, and simulation
- Automotive component testing (ECUs, motors, inverters)
- General R&D and production line 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.
