DC-AC Power Converter Input Testing
Adjustable high-voltage DC power for DC-AC converter development and input testing.
The NICE-POWER R-SPS20010-R is an adjustable DC voltage supply designed for laboratory testing and development of compatible DC-AC power converters. With a 0–200V DC output range, a maximum output current of 10A, and rated power of 2000W, it provides a flexible DC input source for evaluating converter circuits and related power electronics under different supply conditions.
When developing or evaluating a DC-AC converter, engineers may need to apply different DC input voltages to examine the device under selected test conditions. The R-SPS20010-R allows users to adjust voltage and current from the front panel and monitor the supply's output through its voltage, current, and power displays. CV/CC indicators provide a visual reference to the power supply's operating mode, while the Output ON/OFF control helps manage DC output during test preparation and operation. The R-SPS20010-R programmable-control version also features USB, RS-232, and RS485 communication interfaces for connection to compatible external control systems.
Key Features
Adjustable 0–200V DC Output for DC-AC Converter Input Testing
DC-AC power converters can have different DC input requirements depending on their design and intended application. The R-SPS20010-R provides adjustable 0–200V DC output, allowing engineers to configure suitable input voltage conditions for compatible DC-AC converters and related power conversion modules.
With a maximum output current of 10A and rated power of 2000W, this DC voltage supply supports a range of converter input testing requirements when the selected voltage, current, and power remain within the unit's rated specifications.
10A Output Current and 2000W Rated Power for Converter Evaluation
The R-SPS20010-R delivers up to 10A output current and 2000W rated power, making it suitable for compatible power converter circuits and modules that require an adjustable higher-voltage DC input source.
This output capacity gives engineers flexibility when configuring test conditions for different converter designs. The maximum available current depends on the selected output voltage and the 2000W power limit, so the output settings should be selected according to the device under test and the requirements of the test procedure.
Digital Voltage, Current, and Power Display for Input Monitoring
The four-digit voltage/current display and separate power display provide visible readings of the power supply's output. During DC-AC converter input testing, technicians can monitor the applied DC voltage, delivered current, and output power directly from the front panel.
These readings help users check the supply conditions used during a test and record the output values associated with different input settings. They represent the power supply's output readings and do not independently measure the converter's AC output or conversion efficiency.
CV/CC Indicators for Operating-Mode Monitoring
The CV and CC indicators show whether the power supply is operating in constant-voltage or constant-current mode. Together with the voltage and current readings, these indicators help engineers observe the power supply's operating state while a compatible converter is connected as the test load.
This feedback is useful when configuring input conditions and monitoring the supply during different stages of a bench test.
Encoder Knob Adjustment for Flexible DC Input Settings
The front-panel encoder knobs allow users to adjust voltage and current settings according to the requirements of the test setup. This makes it convenient to configure different DC input conditions for compatible DC-AC converters without relying on a separate fixed-voltage source for every test setting.
All selected settings should remain within the power supply's rated voltage, current, and power limits, as well as the input specifications of the connected converter.
Output ON/OFF Control for Convenient Test Operation
The dedicated front-panel Output ON/OFF control allows users to enable or disable the DC output during test preparation and operation. It provides a convenient way to manage power delivery when preparing test connections, beginning a test, or completing individual steps in a converter evaluation procedure.
Users should follow the operating instructions for both the power supply and the connected converter when connecting or disconnecting test equipment.
USB, RS-232, and RS485 Interfaces for Programmable Test Setups
The R-SPS20010-R programmable-control version is equipped with USB, RS-232, and RS485 communication interfaces. These interfaces support connection to compatible external control equipment for supported computer-assisted or automated testing setups.
For engineering laboratories that use external control systems, these interfaces can help integrate the DC voltage supply into an existing converter testing workflow. Available control operations depend on the connected system and its supported communication commands.
