With up to 3A output current and 360W maximum power, the Adjustable DC Bench Supply provides controlled DC power for compatible DC-DC converters and power conversion circuits. Users can select suitable voltage and current settings according to the requirements of the device under test.
CV/CC Operation for Different Converter Test Conditions
The SPS-C1203 supports Constant Voltage and Constant Current operation, allowing the power supply to respond according to the connected load and selected output conditions. This provides a practical power source for different stages of DC-DC Converter Development and Testing.
4-Knob Adjustment for Direct Parameter Changes
The 4-Knob Adjustment design provides separate controls for voltage and current settings. Users can directly adjust the output conditions from the front panel when changing converter input parameters during development, troubleshooting, or repeated testing.
Voltage, Current, and Power Display for Test Observation
The built-in display provides voltage, current, and power readings during operation. These readings allow users to observe the electrical conditions supplied to the DC-DC converter and compare different test points during converter development and testing.
Output Switch for Controlled Test Sequences
The Output Switch allows users to control when the DC output is applied to the connected converter. Test parameters can be configured before enabling the output, which is useful when setting up repeated DC-DC Converter Testing procedures.
5V/2A USB Output for Compatible Bench Accessories
The built-in 5V/2A USB Output provides auxiliary power for compatible USB accessories used around the development workstation, helping reduce the need for an additional low-power USB source.
