Adjustable DC Source for Substation Auxiliary
System Testing NICE-POWER R-SPS20010 200V 10A
2000W with Output Control
Substation DC Auxiliary Power System Testing
Adjustable high-voltage DC power for substation auxiliary system testing and validation.
The NICE-POWER R-SPS20010-R is a high-power adjustable DC source designed for laboratory and engineering test environments that require higher-voltage DC output. With an adjustable output range of 0–200V, a maximum output current of 10A, and rated power of 2000W, it provides a configurable DC supply for testing compatible substation auxiliary power circuits, DC electrical modules, and related control-power equipment within the unit's rated specifications.
During substation DC auxiliary system testing, engineers may need to configure different supply voltage conditions and monitor the power delivered to a test load. The R-SPS20010-R makes this process more convenient with front-panel encoder adjustment, voltage and current readouts, and a separate power display. 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 is also equipped with USB, RS-232, and RS485 communication interfaces for connection to compatible external control systems.
Key Features
Adjustable 0–200V DC Output for Substation Auxiliary Power System Testing
Substation auxiliary power circuits can require specific DC supply conditions during equipment development, maintenance, and bench validation. The R-SPS20010-R offers an adjustable 0–200V DC output, allowing technicians to configure suitable voltage settings for compatible auxiliary power modules and DC control-power circuits.
With a maximum output current of 10A and rated power of 2000W, this adjustable DC source supports a range of higher-voltage test requirements. The selected voltage, current, and power must remain within the unit's rated limits and the requirements of the equipment under test.
10A Output and 2000W Rated Power for DC Auxiliary Circuit Evaluation
The R-SPS20010-R delivers up to 10A output current with a rated power of 2000W, making it suitable for compatible substation DC auxiliary circuits and electrical modules that require an adjustable higher-voltage DC source.
This output capacity gives technicians flexibility when configuring test conditions for different loads. The maximum available current depends on the selected output voltage and the 2000W power limit, so the test settings should be selected according to the specifications of the connected equipment.
Voltage, Current, and Power Display for Output Monitoring
The four-digit voltage/current display and separate power display provide clear readings of the power supply's output. During auxiliary power system 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 output values as part of their testing procedure. They represent the power supply's output readings and do not replace independent measurements of the substation equipment being evaluated.
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 displayed voltage and current, these indicators help technicians observe the supply's operating state while testing compatible DC auxiliary power circuits and electrical modules.
This feedback is useful when configuring test conditions and monitoring how the power supply operates under the connected load.
Encoder Knob Adjustment for Flexible DC Voltage Settings
The front-panel encoder knobs allow users to adjust voltage and current settings according to the requirements of the test procedure. This makes it convenient to configure different DC supply conditions for compatible auxiliary power modules without relying on a separate fixed-voltage source for every setting.
All selected settings should remain within the power supply's rated voltage, current, and power limits, as well as the operating requirements of the connected equipment.
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 as required during testing. It provides a convenient way to manage power delivery when preparing test connections, starting a test, or completing individual steps in an evaluation procedure.
For substation-related equipment testing, users should follow the applicable test procedure and equipment instructions when connecting or disconnecting the load. The output switch does not replace required electrical isolation or safety measures.
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 test setups.
For engineering laboratories that use external control systems, the communication interfaces can help integrate the DC source into an existing test workflow. Available control operations depend on the connected equipment and its supported communication commands.
