80V 20A 1600W Regulated DC Supply for 48V
Automotive DC-DC Converter Testing NICE-POWER
R-SPS8020 with CV/CC Indicators
48V Automotive DC-DC Converter Input Testing
Bring more flexibility to your 48V automotive DC-DC converter testing with an adjustable high-power DC supply.
The NICE-POWER R-SPS8020-R regulated DC power supply delivers adjustable output from 0–80V, up to 20A, and 1600W of rated power. Its wide voltage adjustment range allows engineers to configure DC input conditions around the nominal 48V level for compatible automotive DC-DC converter testing, power module evaluation, and electronics development.
Instead of relying on a fixed-voltage source, technicians can adjust the output to suit different test requirements within the power supply’s rated limits. The voltage, current, and power displays provide a clear view of the supply’s output, while the CV/CC indicators show its operating mode. Front-panel encoder knobs and Output ON/OFF control make everyday bench testing more convenient. For compatible computer-controlled test setups, the R-SPS8020-R also includes USB, RS-232, and RS485 communication interfaces.
Key Features
Adjustable 0–80V Output for 48V Automotive DC-DC Converter Testing
A nominal 48V system may need to be evaluated under different input-voltage conditions. The R-SPS8020-R provides an adjustable 0–80V DC output, giving technicians the flexibility to set suitable input voltage levels for compatible 48V automotive DC-DC converters and related power modules.
With up to 20A output current and 1600W rated power, this regulated DC supply supports a range of bench test requirements within its voltage, current, and power limits.
Up to 20A Output and 1600W Power for Demanding Bench Tests
Converter evaluation often requires a stable source of DC input power appropriate to the device under test. The R-SPS8020-R provides current capability up to 20A and rated output power of 1600W, making it suitable for compatible automotive power modules and other DC-DC converter circuits that require more than a low-current laboratory supply can provide.
The actual available current depends on the selected output voltage and the unit’s maximum power rating.
CV/CC Indicators for Clear Operating-Mode Feedback
Know which operating mode the power supply is using while you work. The CV and CC indicators show whether the unit is operating in constant-voltage or constant-current mode, giving technicians a useful reference during converter input testing.
Used together with the voltage and current displays, these indicators help users observe the supply’s operating condition as the connected load changes.
Voltage, Current, and Power Displays for Better Test Visibility
Keep key output readings in view while configuring your test. The four-digit voltage/current display and separate power display let technicians monitor the supplied voltage, delivered current, and output power directly from the front panel.
This visible feedback helps make bench testing more straightforward when setting up input conditions, comparing test settings, or documenting the power supply readings for a test procedure.
Encoder Knobs and Output ON/OFF Control for Easier Operation
Make adjustments directly from the front panel. The encoder knobs allow users to set voltage and current, while the dedicated Output ON/OFF control lets them enable or disable the DC output as required during the testing process.
These controls provide a practical workflow for connecting test equipment, configuring the desired supply conditions, and managing individual test steps according to the equipment’s operating instructions.
USB, RS-232, and RS485 Interfaces for Programmable Test Setups
For test environments that use external control equipment, the R-SPS8020-R programmable-control version features USB, RS-232, and RS485 communication interfaces. These interfaces support connection to compatible computer-controlled or automated test systems, helping the power supply fit into an existing laboratory or engineering workflow.
Available control operations depend on the compatibility of the external system and its supported communication commands.
Applications
48V Automotive DC-DC Converter Input Testing
Configure adjustable DC input conditions for compatible 48V automotive DC-DC converters during bench evaluation and development. The 0–80V range gives technicians flexibility when selecting test input voltages within the power supply’s rated specifications.
