Key Features
15V 30A 450W High Current DC Power Supply
The R-SPS1530S provides 0–15V adjustable voltage, 0–30A adjustable current, and up to 450W output power. This high-current DC Power Supply is suitable for compatible DC motors and other low-voltage loads that require higher current during testing.
OCP and OVP Protection for DC Motor Testing
The R-SPS1530S includes OCP and OVP functions to provide protection during DC Motor Testing. These protection functions can help reduce the risk associated with excessive current or voltage conditions when testing compatible motor loads within the power supply's rated range.
Four-Digit Voltage, Current, and Power Display
The four-digit display provides clear readback of voltage, current, and power during testing. This allows users to monitor the main output parameters while adjusting the DC Power Supply for different motor test conditions.
Precision Encoder Adjustment
The encoder provides precision adjustment for the power supply settings. During DC Motor Testing, users can make controlled changes to the output settings when evaluating motor operation at different voltage and current conditions.
Output ON/OFF Control
The dedicated Output ON/OFF function allows users to activate or disable the DC output independently during testing. This provides convenient control when connecting, adjusting, or changing a compatible motor test setup.
M1–M3 Memory Presets
The R-SPS1530S provides three groups of memory functions, M1–M3. Frequently used power supply settings can be stored and recalled, which can simplify repeated DC Motor Testing where the same voltage and current conditions are used multiple times.
Panel Lock and Adjustable Buzzer
The Panel Lock Button helps prevent unintended changes to settings during testing. The control knob also includes a buzzer that can be set to mute according to the user's operating preference.
Front and Rear Dual Output Ports
The R-SPS1530S provides output ports on both the front and rear panels. The product specifications indicate that the front panel is suitable for outputs below 5A, while the rear output can be used at full power, providing flexible connection options for different DC Motor Testing setups.
USB and Optional RS232 / RS485 Interfaces
The series provides a standard USB port, with RS232 and RS485 available as optional interfaces. These interface options can provide additional connectivity for compatible testing and control setups when the corresponding interface configuration is selected.
Applications
DC Motor Testing
The R-SPS1530S provides adjustable 0–15V voltage and up to 30A current for compatible DC Motor Testing applications. Users can configure different voltage and current conditions within the 450W rated output range to evaluate motor operation.
DC Motor Development and Evaluation
During DC motor development and evaluation, the High Current DC Power Supply can provide adjustable DC power while the four-digit display allows users to monitor voltage, current, and power. This supports controlled evaluation of compatible motor prototypes and test units.
Motor Startup Testing
DC motors can require higher current during startup than during normal operation. With up to 30A current output, the R-SPS1530S provides a high-current DC source for compatible motor startup testing within the 15V, 30A, and 450W output limits.
Motor Load Testing
The adjustable voltage and current output can be used to provide controlled power for compatible motor load testing. Users can change the output settings and monitor the displayed voltage, current, and power while evaluating the motor under different test conditions.
Motor Controller Testing
The R-SPS1530S can provide adjustable DC power for compatible low-voltage motor controller test setups. Its 0–15V voltage range and up to 30A current capability provide a flexible power source for controller and motor system testing within the rated specifications.
DC Fan and Actuator Testing
The High Current DC Power Supply can be used for testing compatible DC fans, actuators, and other motor-driven DC loads. The adjustable output and OCP function provide practical support for controlled testing within the rated operating range.
Repeated Motor Test Conditions
The M1–M3 memory functions allow users to store and recall three groups of settings. This can be useful when DC Motor Testing requires repeated evaluation under predefined voltage and current conditions.
Motor Test Bench Power Supply
With front and rear output ports, Output ON/OFF control, precision encoder adjustment, and four-digit voltage, current, and power display, the R-SPS1530S can serve as a High Current DC Power Supply for motor test benches requiring adjustable DC power within the 450W output limit.
Low-Voltage High-Current DC Equipment Testing
Beyond DC Motor Testing, the 0–15V and 0–30A output range can support other compatible low-voltage, high-current DC equipment and load testing applications that remain within the 450W rated power limit.
