DC Power Supply for Converter Module Verification,
NICE-POWER R-SPS2005, 200V 5A 1000W for
Bench Testing
Key Features
Wide Voltage Range for Converter Input Simulation
The NICE-POWER R-SPS2005 delivers an adjustable DC output from 0 to 200V, with a maximum output current of 5A and rated power of 1000W. This voltage range makes it suitable as an input source for compatible DC power converter modules whose specified input requirements fall within the supply's operating limits. Engineers can select a suitable DC input level to examine how a converter module operates under defined bench conditions.
Output Ripple Specifications for Test Equipment Selection
When selecting a DC power supply for converter module verification, input-source quality is an important consideration. The R-SPS2005 has a specified voltage ripple of ≤400mVp-p / ≤60mVrms and current ripple of ≤20mArms, measured over the stated 20Hz–20MHz range. Engineers can compare these figures with the requirements of the converter under test when planning a measurement setup.
Readable Output Values During Converter Operation
The voltage and current four-digit displays, together with the power display, provide a direct view of the power supply's output values. This helps users observe the DC input delivered to the converter while conducting bench experiments. To determine conversion efficiency or verify the converter's output voltage and ripple, additional measurement equipment is required.
Regulation and Setting Accuracy for Repeatable Setup
The R-SPS2005 specifies voltage load regulation of ≤0.1% + 10mV and line regulation of ≤0.01% + 2.5mV. Voltage setting and readback accuracy are specified at ≤0.05% + 10mV, while current setting and readback accuracy are ≤0.01% + 10mA. These specifications help engineers assess whether the supply is appropriate for the input conditions required by their converter module tests.
Manual and Programmable Model Options
The R-SPS2005 uses manual front-panel adjustment, while the R-SPS2005-R is the programmable version for compatible control applications. USB, RS232, and RS485 interfaces are optional configurations, not guaranteed standard features. Users planning computer-controlled testing should confirm the available interface and supported commands for their exact model.
Practical Connections for a Converter Test Bench
Front-panel and rear-panel output connections accommodate different bench layouts. The front-panel output current is limited to below 5A, while the rear-panel output supports the full rated output capability within the product specifications. The encoder knob and Output ON/OFF control allow users to set the supply and control power delivery during test setup.
Applications
DC-DC Converter Input Voltage Evaluation
Use the R-SPS2005 as an adjustable DC input source when evaluating a compatible DC-DC converter. Engineers can select input voltage conditions within the converter's specified operating range and use external instruments to measure the converter's resulting output voltage, current, and performance.
Power Conversion Circuit Design Verification
During power conversion circuit development, the supply can provide the DC input required to evaluate a newly assembled board or a revised circuit design. This allows engineers to investigate the circuit's response to selected input conditions using an oscilloscope, multimeter, electronic load, or other suitable instruments.
Converter Startup Threshold Investigation
For converter modules that require a defined input voltage to start, the adjustable DC output can be used to establish selected input levels during a controlled bench procedure. Engineers can observe the converter's startup behavior with suitable external instruments. The power supply does not automatically detect startup thresholds or execute voltage sweeps.
Converter Performance and Efficiency Measurement Setup
The R-SPS2005 can serve as the DC source in a broader converter performance test setup. When efficiency, output ripple, load response, or conversion losses need to be quantified, use appropriate external measurement instruments and a suitable electronic load. The power supply's own voltage, current, and power displays show its output values; they do not independently measure the converter's complete input-to-output performance.

Why Choose NICE-POWER R-SPS2005?
Choosing a DC power supply for converter module verification involves more than matching voltage and current ratings. The NICE-POWER R-SPS2005 combines a 0–200V adjustable output, 5A maximum current, 1000W rated power, and documented regulation and ripple specifications for engineering bench applications.
Its broad voltage range supports compatible converter input requirements, while the displayed output values help users monitor the DC source during experiments. For manually configured tests, the R-SPS2005 offers front-panel adjustment; for compatible control workflows, the R-SPS2005-R provides a programmable-version option subject to its selected interface and supported functions.
The R-SPS2005 series is a DC source for converter testing, not a complete converter analyzer. Pair it with appropriate external instruments and a suitable electronic load when the test requires verified output characteristics, efficiency calculations, or dynamic performance measurements.
