CV/CC Indicator Bench DC Power Supply for Busbar
and Conductor Testing NICE-POWER R-SPS30100
0-30V 0-100A 3000W
The NICE-POWER R-SPS30100-R is a high-current bench DC power supply developed for testing applications that require low voltage and substantial current. With an adjustable output of 0–30V, a maximum output current of 100A, and rated power of 3000W, it provides a controlled DC power source for busbar assemblies, electrical conductors, and other compatible low-voltage, high-current test loads.
During a test, users can adjust the output settings using the front-panel encoder knobs and monitor voltage, current, and power through the displays. The CV/CC indicators provide a visual reference to the power supply’s operating mode, while the Output ON/OFF control allows convenient management of the DC output. For test benches using compatible external control equipment, the R-SPS30100-R also provides USB, RS-232, and RS485 communication interfaces.
Key Features
0–30V, 0–100A DC Output for Busbar and Conductor Testing
The R-SPS30100-R combines a low-voltage output range of 0–30V with current capability up to 100A and rated power of 3000W. This output range is suitable for supplying compatible busbar assemblies and electrical conductors during high-current DC tests, provided the required test conditions remain within the power supply’s ratings.
CV/CC Indicators for Clear Operating-Mode Reference
The constant-voltage (CV) and constant-current (CC) indicators show the power supply’s operating mode. During busbar and conductor testing, users can observe these indicators together with the voltage and current displays to understand how the power supply is operating under the connected load.
Voltage, Current, and Power Displays for Output Monitoring
The voltage/current display and separate power display provide visible readings of the power supply’s output. These readings help users check the applied voltage, delivered current, and output power while carrying out a test. When the test requires independent measurements of conductor resistance, temperature rise, or current distribution, suitable external measuring instruments are needed.
Encoder Adjustment for Different Test Conditions
The front-panel encoder knobs allow users to adjust voltage and current settings according to the requirements of the test setup. This makes it easier to configure different DC supply conditions for compatible busbar and conductor assemblies without changing the power source for each setting.
Output ON/OFF Control for Practical Test Operation
The front-panel Output ON/OFF control lets users enable or disable the DC output during test preparation and operation. It provides a convenient way to manage power delivery when starting or stopping a test sequence. Test connections should always be made in accordance with the power supply and test fixture operating instructions.
USB, RS-232, and RS485 Interfaces for External Control
The R-SPS30100-R programmable-control version is equipped with USB, RS-232, and RS485 communication interfaces. These interfaces allow connection to compatible external control equipment for supported computer-assisted or automated test setups. The control functions available depend on the connected equipment and supported communication commands.
Applications
DC Busbar Current Testing
Supplies adjustable low-voltage DC power to compatible busbar test assemblies requiring high current. The output displays help users monitor the power supplied during the test, while any additional measurements must be performed with suitable measurement equipment.
Electrical Conductor Current Testing
Provides a high-current DC source for testing compatible electrical conductors under defined supply conditions. Users should select voltage and current settings according to the test plan, conductor specifications, fixture limitations, and power supply ratings.
High-Current DC Connection and Power Path Testing
Supports bench testing of compatible DC connections, conductive assemblies, and low-voltage power paths that require an adjustable DC source. The maximum output of 100A makes the unit suitable for test setups whose current and power requirements fall within its rated capabilities.
Computer-Controlled DC Test Bench Integration
USB, RS-232, and RS485 communication interfaces support connection to compatible external control equipment. This can help integrate the power supply into a computer-assisted test bench where the supported interface and control commands meet the requirements of the application.
