KUAIQU SPPS305-2KD Adjustable DC Lab Power
Supply 0-30V 0-5A
Adjustable Dual Channel DC Power Supply for Portable Measurement Instrument Testing
The KUAIQU SPPS305-2KD is an Adjustable DC Lab Power Supply designed to provide stable, adjustable DC power for compatible portable measurement instruments, measurement circuit boards, data acquisition modules, and related electronic test setups. It features two independent output channels, with each channel supporting 0-30V, 0-5A, and 150W output, allowing users to establish separate DC power conditions for different circuits or devices during development and laboratory evaluation.
Portable Measurement Instrument Testing may involve different power requirements for instrument circuits, sensor interfaces, signal-conditioning boards, and data acquisition modules. The SPPS305-2KD supports Independent, Series, and Parallel output modes, together with Negative-0-Positive Voltage output, providing flexible DC power configurations for compatible electronic equipment. Precision encoder adjustment, OCP and OVP protection, independent Output ON/OFF control, and 8-group memory provide practical control for power adjustment and repeated testing procedures.
Key Features
Dual Independent Outputs for Portable Measurement Instrument Testing
The SPPS305-2KD provides two independent DC output channels, with each channel supporting 0-30V, 0-5A, and 150W output.
For Portable Measurement Instrument Testing, the two channels can be adjusted independently to provide separate DC power conditions for compatible instrument circuits, sensor interfaces, or related electronic modules. This is useful when a laboratory setup requires more than one adjustable DC output for different circuit sections or devices.
Negative-0-Positive Voltage Output for Measurement Circuit Power Supply
The SPPS305-2KD supports Negative Voltage - 0 - Positive Voltage output mode, providing a flexible power configuration for compatible measurement circuits that require different voltage polarities.
This function can be useful when developing or evaluating measurement circuit boards, signal-conditioning circuits, and other electronic modules that require positive and negative supply conditions. Users can configure the output according to the connected circuit's voltage requirements within the supported operating range.
Independent, Series, and Parallel Output Modes
The SPPS305-2KD supports Independent, Series, and Parallel output configurations for different Portable Measurement Instrument Testing requirements.
In Independent Mode, both channels provide separate 0-30V and 0-5A outputs. In Series Mode, the two channels can provide up to 0-60V and 0-5A. In Parallel Mode, the two channels can provide up to 0-30V and 0-10A.
The dedicated Series and Parallel output port avoids complicated external wiring when changing the output configuration. This provides additional flexibility when compatible measurement equipment or electronic circuits require different voltage or current conditions.
Precision Encoder Adjustment
The SPPS305-2KD uses precision encoder adjustment for voltage and current control.
During Portable Measurement Instrument Testing, users can adjust the DC power conditions according to the requirements of the connected instrument circuit or electronic module. The 10mV voltage setting resolution and 1mA current setting resolution support fine output adjustment within the specified operating range.
OCP and OVP Protection for Instrument Circuit Testing
The SPPS305-2KD provides Over Current Protection (OCP) and Over Voltage Protection (OVP).
During instrument circuit development and power-up evaluation, incorrect output settings may cause unexpected operating conditions in connected equipment. OCP and OVP provide protection when the corresponding protection conditions are triggered, helping protect the power supply and connected loads.
Output ON/OFF Control and 8-Group Memory
The SPPS305-2KD provides independent Output ON/OFF control and supports 8 groups of parameter memory.
The memory function provides two groups for each independent channel, two groups for Series Mode, and two groups for Parallel Mode. Frequently used voltage and current settings can be stored and recalled for repeated Portable Measurement Instrument Testing, reducing the need to configure the same power conditions repeatedly.
Panel Lock with Buzzer
The SPPS305-2KD includes a Panel Lock function and buzzer.
During repeated instrument development and evaluation, the Panel Lock function helps prevent unintended changes to configured settings. The buzzer provides operating feedback during use.
Applications
Portable Measurement Instrument Circuit Development
The SPPS305-2KD provides adjustable DC power for compatible measurement instrument circuits during prototype development and laboratory evaluation.
Its dual independent outputs allow users to establish separate power conditions for different circuit sections, while the adjustable voltage and current settings support different development requirements within the rated output range.
Handheld Measurement Device Power Testing
The adjustable DC outputs can supply power to compatible electronic circuits and modules used in handheld measurement devices during development or repair evaluation.
Users can configure the voltage and current according to the requirements of the connected circuit. The power supply does not replace the handheld instrument's own measurement functions.
Data Acquisition Module Testing
The SPPS305-2KD can provide adjustable DC power to compatible data acquisition modules and their related electronic circuits during development and functional evaluation.
The independent output channels can support separate power requirements when the connected test setup requires multiple DC supply conditions.
Sensor Interface and Signal-Conditioning Circuit Testing
The adjustable outputs can supply compatible sensor interface boards and signal-conditioning circuits during circuit development and evaluation.
The Negative-0-Positive Voltage output mode provides additional power configuration flexibility for compatible circuits that require positive and negative supply conditions. Series and Parallel modes can also be selected according to the circuit's voltage and current requirements.
