DC Test Supply for 48V Auxiliary Power System
Testing NICE-POWER R-SPS8020 0-80V 0-20A
1600W with CV/CC Indicators
48V DC Auxiliary Power System Testing
Flexible DC power for testing 48V auxiliary power systems and related electrical modules.
The NICE-POWER R-SPS8020-R is a high-power regulated DC test supply designed for bench testing applications that require adjustable voltage and reliable output monitoring. With an adjustable output range of 0–80V, a maximum output current of 20A, and rated power of 1600W, it provides a versatile DC source for evaluating compatible 48V auxiliary power modules, DC supply circuits, and related electrical components within the unit’s rated specifications.
Whether you are developing a DC auxiliary power module or evaluating an existing power circuit, adjustable output settings make it easier to configure different test conditions without changing the power source. The voltage, current, and power displays provide clear output readings, while the CV/CC indicators show the power supply’s operating mode. Front-panel encoder knobs and Output ON/OFF control simplify routine bench operation. The R-SPS8020-R programmable-control version also features USB, RS-232, and RS485 communication interfaces for connection to compatible external control systems.
Key Features
Adjustable 0–80V Output for 48V DC Auxiliary Power System Testing
A 48V auxiliary power system may need to be evaluated under different DC input conditions during development, troubleshooting, or bench verification. The R-SPS8020-R provides an adjustable 0–80V DC output, allowing technicians to configure suitable supply voltage settings for compatible 48V auxiliary power modules and related DC circuits.
With a maximum output current of 20A and rated power of 1600W, this regulated DC test supply supports a range of testing requirements while keeping the selected voltage, current, and power within its rated limits.
Up to 20A Output and 1600W Rated Power for DC Module Evaluation
Power modules and auxiliary DC circuits can have different input power requirements. The R-SPS8020-R supplies up to 20A at a rated output power of 1600W, making it suitable for compatible auxiliary power modules and electrical assemblies that require a higher-capacity adjustable DC source.
The available output current depends on the selected voltage and the power supply’s maximum power rating. Users should configure the output according to the requirements of the device under test.
CV/CC Indicators for Clear Operating-Mode Monitoring
The CV and CC indicators show whether the power supply is operating in constant-voltage or constant-current mode. During 48V auxiliary power system testing, technicians can observe these indicators together with the voltage and current readings to understand the supply’s operating condition under the connected load.
This visual feedback helps users monitor the power supply during test procedures without confusing the supply’s operating-mode indication with independent measurements of the system under test.
Voltage, Current, and Power Displays for Output Visibility
The four-digit voltage/current display and separate power display allow technicians to check the power supply’s output readings directly from the front panel. Users can monitor the applied voltage, delivered current, and output power while configuring test conditions or evaluating compatible auxiliary power modules.
Clear output readings make it more convenient to record supply conditions and compare different test settings during development and bench verification.
Encoder Knob Adjustment for Flexible DC Test Conditions
The front-panel encoder knobs allow users to adjust voltage and current settings according to the requirements of the test setup. This flexibility is useful when evaluating compatible 48V auxiliary power circuits at different DC input settings, without requiring a separate fixed-voltage source for every test condition.
All settings should remain within the power supply’s rated voltage, current, and power limits.
Output ON/OFF Control for Convenient Test Operation
The dedicated front-panel Output ON/OFF control lets users enable or disable the DC output as needed during testing. It provides a convenient way to manage power delivery when preparing connections, starting a test, or completing individual steps in a test procedure.
Users should follow the operating instructions for both the power supply and the connected equipment when setting up or changing test connections.
USB, RS-232, and RS485 Interfaces for Programmable Test Setups
The R-SPS8020-R programmable-control version is equipped with USB, RS-232, and RS485 communication interfaces. These interfaces support connection to compatible external control equipment for computer-assisted or automated test setups.
This connectivity can be useful when integrating the power supply into an existing laboratory or engineering workflow. Available control operations depend on the external system’s compatibility and supported communication commands.
