0-150V 0-10A 1500W DC Voltage Source for
110V/125V Protection Relay Auxiliary Testing
NICE-POWER R-SPS15010
110V/125V DC Protection Relay Auxiliary Supply Testing Validation
Flexible high-voltage DC power for protection relay auxiliary supply testing and validation.
The NICE-POWER R-SPS15010-R is an adjustable DC voltage source designed for laboratory and bench testing applications that require higher DC voltage. With an adjustable output range of 0–150V, a maximum output current of 10A, and rated power of 1500W, it provides a configurable DC supply for testing compatible 110V/125V protection relay auxiliary circuits and related electrical equipment within the power supply’s rated output limits.
During protection relay auxiliary supply testing, technicians may need to configure different DC input voltages and observe the power supply’s output under the selected test conditions. The R-SPS15010-R supports this workflow through front-panel voltage and current adjustment, a digital voltage/current display, and a separate power display. Its CV/CC indicators provide a visual reference to the operating mode, while the Output ON/OFF control allows convenient management of DC output during test preparation and operation. The programmable-control version also offers USB, RS-232, and RS485 communication interfaces for connection to compatible external control systems.
Key Features
Adjustable 0–150V DC Output for 110V/125V Protection Relay Testing
Protection relay auxiliary circuits may require different DC supply voltages during development, inspection, and bench validation. The R-SPS15010-R provides an adjustable 0–150V DC output, allowing technicians to configure suitable supply conditions for compatible 110V/125V protection relay auxiliary circuits and related DC equipment.
With a maximum output current of 10A and rated power of 1500W, this DC voltage source supports a range of auxiliary supply testing requirements, provided the selected voltage, current, and power remain within the unit’s rated specifications.
Up to 10A Output and 1500W Rated Power for Auxiliary Supply Evaluation
The R-SPS15010-R delivers up to 10A output current with a rated output power of 1500W. This capacity makes it suitable for compatible auxiliary power circuits and electrical equipment that require an adjustable higher-voltage DC source.
The maximum current available at a particular voltage is limited by the power supply’s 1500W rating. Users should select output settings according to the protection relay’s auxiliary supply requirements and the specifications of the connected test equipment.
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. During protection relay auxiliary supply testing, technicians can use these indicators together with the voltage and current readings to observe the power supply’s operating state under the connected load.
These indicators provide operating-mode information from the power supply; they do not independently verify the protection relay’s trip logic, protection settings, or functional performance.
Digital Voltage, Current, and Power Display for Clear Test Readings
The four-digit voltage/current display and separate power display allow technicians to view the supply’s output readings directly from the front panel. This helps users monitor the applied DC voltage, delivered current, and output power when configuring auxiliary supply test conditions.
Visible output readings also make it easier to record the supply conditions used during bench testing and compare different voltage settings during a validation procedure.
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 setup. This is useful when testing compatible 110V/125V DC auxiliary supply circuits at different input voltage settings without changing to a separate fixed-voltage source for every test condition.
All selected settings should remain within the power supply’s rated voltage, current, and power limits, as well as the test requirements of the connected equipment.
Output ON/OFF Control for Convenient Test Procedures
The front-panel Output ON/OFF control allows users to enable or disable the DC output during testing. It provides a convenient way to manage power delivery when preparing connections, starting a test, or completing individual test steps.
For protection relay testing, users should follow the applicable test procedure and equipment instructions when connecting or disconnecting the auxiliary supply. The output switch should not be treated as a substitute for the required electrical isolation and safety procedures.
USB, RS-232, and RS485 Interfaces for Programmable Test Setups
The R-SPS15010-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 and relay testing environments that already use external control systems, these interfaces can help integrate the DC voltage source into a compatible test workflow. Available control operations depend on the connected system and its supported communication commands.
