Switching Converter Input Evaluation with
NICE-POWER R-SPS6020 Adjustable DC Power
Supply 60V 20A 1200W
Key Features
1. Adjustable 0–60V DC Output for Switching Converter Input Evaluation
The NICE-POWER R-SPS6020 series provides an adjustable DC output from 0 to 60V for switching converter input evaluation, prototype development, and bench power-up verification. Users can set a suitable DC input voltage for compatible switching converters and power modules, then observe their basic startup and operating behavior within the devices' specified input ranges.
The series is suitable for applications that require adjustable DC input power during development and troubleshooting. Always follow the device manufacturer's input voltage requirements and startup procedures.
2. 20A Output and 1200W Rated Power
With a maximum output current of 20A and a rated power of 1200W, the R-SPS6020 series supplies DC input power to compatible switching converters and DC power modules. Its output capacity supports bench evaluations that require more power than low-current laboratory supplies can provide.
Actual operating output depends on the selected voltage, connected load, and power limit. Keep the voltage, current, and total output power within the power supply's rated specifications and the device under test's input limits.
3. Four-Digit Voltage and Current Display with Power Readout
The four-digit display shows the power supply's output voltage and current, while the power display helps users monitor the output power delivered to the switching converter. These readings are useful for checking the applied DC input during converter startup, input-voltage adjustment, and preliminary troubleshooting.
The displayed readings describe the power supply's output. They do not directly measure the switching converter's own output voltage, output ripple, transient response, or conversion efficiency. Use suitable external instruments when those measurements are required.
4. Constant Voltage and Constant Current (CV/CC) Operation
The R-SPS6020 series supports automatic switching between constant voltage (CV) and constant current (CC) operation according to the load and operating conditions. Users can set the desired voltage and current limit to suit the intended input evaluation.
CV/CC operation supports different load conditions during bench testing, but it does not replace dedicated converter protection testing or provide automatic analysis of converter performance.
5. Manual and Programmable Versions to Suit Different Workflows
The R-SPS6020 series offers two versions for different control requirements:
-
R-SPS6020 Manual Version: Uses the encoder knob for direct manual voltage and current adjustment. It is suitable for routine bench power-up checks, input-voltage evaluation, and troubleshooting where hands-on control is preferred.
-
R-SPS6020-R Programmable Version: Intended for applications requiring programmable control. Confirm the supported control method and installed communication interface before purchase to ensure compatibility with your test setup.
USB, RS-232, and RS-485 communication interfaces are optional configurations. They are not guaranteed to be included as standard on every unit. Automated test sequences, data logging, and software integration should only be specified when supported by the exact purchased configuration.
6. Output ON/OFF Control and Front/Rear Output Terminals
The R-SPS6020 series includes an output ON/OFF control for enabling or disabling the DC output. Front-panel and rear-panel output terminals accommodate different connection and current requirements.
The front-panel output is intended for currents below 5A. For higher-current operation within the unit's rated capability, use the rear-panel output with appropriately rated cables and connectors. Ensure that all connections are secure and suitable for the expected current.
Applications
1. Switching Converter Input Evaluation
Supply a compatible switching converter with adjustable DC input power to check basic startup and operating behavior under selected input conditions. Adjust the supply voltage within the converter's specified input range and monitor the supply's output readings throughout the evaluation.
2. DC-DC Converter Power-Up Verification
Use the R-SPS6020 series as a DC source when powering up DC-DC converter prototypes. Check startup behavior and provide the required input power while using external measurement instruments to evaluate the converter's output voltage, ripple, and other electrical characteristics.
3. Switching Power Module Development and Troubleshooting
Provide adjustable DC input power for compatible switching power modules during development, preliminary verification, and fault investigation. The manual version supports direct adjustments at the bench, while the programmable version is intended for workflows requiring programmable control, subject to the installed configuration.
4. Power Electronics Laboratory Testing
Support laboratory experiments involving switching converters, DC-DC modules, and related power electronics circuits. The R-SPS6020 series provides an adjustable DC source, while suitable external instruments can be used for detailed measurements such as waveform observation, transient response, and conversion efficiency.

Why Choose NICE-POWER R-SPS6020 Series?
The NICE-POWER R-SPS6020 series combines adjustable 0–60V DC output, up to 20A current, and 1200W rated power for switching converter input evaluation, DC-DC converter development, and power electronics bench testing.
Choose the R-SPS6020 for direct manual adjustment during routine bench work, or consider the R-SPS6020-R when programmable control is required and the purchased configuration supports the intended control method. Both versions provide adjustable DC input power and output readings to support preliminary evaluation of compatible switching converters.
For complete converter performance verification, use suitable external instruments to measure the device under test's own input and output characteristics.
Important Note: Verify the converter's input voltage range, polarity, startup requirements, and expected current before connecting it. Do not exceed the supply's 60V, 20A, or 1200W ratings. Use the rear output terminals for currents above 5A with appropriately rated wiring. Communication interfaces are optional and must be confirmed before purchase. Do not assume that every version supports computer control, automated testing, waveform generation, or direct converter performance analysis.
