KUAIQU Analog Circuit and Op Amp
Testing Power Supply SPPS305-2KD 30V
5A 150W×2 with Negative-0-Positive
Voltage
The KUAIQU SPPS305-2KD is an Analog Circuit and Op Amp Testing Power Supply designed for operational amplifier circuits, analog circuit development, circuit verification, and electronics laboratory testing. It provides two independent adjustable output channels, with each channel supporting 0-30V, 0-5A, and 150W output, allowing users to establish separate DC power conditions for analog circuits and related electronic test setups.
Analog Circuit and Op Amp Testing can require flexible power configurations for different circuit designs and supply conditions. The SPPS305-2KD supports independent, series, and parallel output modes, together with Negative-0-Positive Voltage output, providing flexible DC power configurations for analog circuit experiments and Op Amp Testing. Precision encoder adjustment, OCP and OVP, Output ON/OFF control, and 8-group memory provide practical control for circuit adjustment and repeated testing.
Key Features
Dual Output for Analog Circuit and Op Amp Testing
The SPPS305-2KD provides two independent DC output channels, with each channel supporting 0-30V, 0-5A, and 150W output.
For Analog Circuit and Op Amp Testing, the two channels can be adjusted independently to provide separate DC power conditions for different parts of a circuit. This is useful when an analog test setup requires more than one adjustable DC output for circuit sections or related electronic devices.
Negative-0-Positive Voltage for Op Amp Testing
The SPPS305-2KD supports Negative Voltage - 0 - Positive Voltage output mode, providing a flexible power configuration for analog circuits that require positive and negative supply conditions.
This function is particularly useful for Op Amp Testing and analog circuit experiments where bipolar power conditions are required. Users can configure the output according to the required negative, zero, and positive voltage conditions within the supported operating range.
Independent, Series, and Parallel Output Modes
The SPPS305-2KD supports Independent, Series, and Parallel output configurations for different Analog Circuit and Op Amp 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 wiring when changing the output configuration, providing additional flexibility when an analog circuit requires different voltage or current conditions.
Precision Encoder Adjustment
The SPPS305-2KD uses precision encoder adjustment for voltage and current control.
During Analog Circuit and Op Amp Testing, users can make controlled adjustments to the DC power conditions while observing the response of the circuit under test. The 10mV voltage setting resolution and 1mA current setting resolution provide fine adjustment within the specified output range.
OCP and OVP Protection for Circuit Testing
The SPPS305-2KD provides Over Current Protection and Over Voltage Protection for Independent, Series, and Parallel output modes.
During analog circuit testing, incorrect voltage or current settings may cause unexpected operating conditions in the connected circuit. OCP and OVP can turn off the output when the corresponding protection condition is triggered, helping protect the DC Power Supply and connected loads.
Output ON/OFF and 8-Group Memory
The SPPS305-2KD provides dedicated Output ON/OFF control and supports 8 groups of memory.
The memory function provides two groups for each independent channel and two groups for Series and Parallel modes. Frequently used voltage and current settings can be stored and recalled for repeated Analog Circuit and Op Amp Testing, reducing the need to repeatedly configure the same test conditions.
Panel Lock with Buzzer
The SPPS305-2KD includes a Panel Lock function with buzzer to help prevent unintended changes to configured settings during testing.
For repeated Op Amp Testing and analog circuit experiments, the Panel Lock function can help maintain the selected voltage and current settings while the circuit is being evaluated.
Applications
Op Amp Circuit Testing
The SPPS305-2KD provides adjustable DC power for operational amplifier circuits during development, verification, and laboratory testing.
Its dual output design and Negative-0-Positive Voltage output mode provide flexible power configurations for Op Amp Testing where positive and negative supply conditions may be required.
Analog Circuit Development
The adjustable voltage and current outputs allow users to establish different DC power conditions for analog circuit development and testing.
The two independent channels can be configured separately when an analog circuit requires multiple adjustable supply conditions. Series and Parallel modes can also be selected when the required voltage or current falls within the corresponding operating range.
Bipolar Supply Testing
Analog circuits may require both positive and negative supply conditions during testing.
The Negative-0-Positive Voltage output mode of the SPPS305-2KD provides a practical configuration for circuits that require bipolar power conditions. The dual output design also allows separate output conditions to be established when required by the test setup.
Repeated Analog Circuit Testing
For repeated Analog Circuit and Op Amp Testing, the 8-group memory function can store commonly used output settings for Independent, Series, and Parallel modes.
Combined with precision encoder adjustment, Output ON/OFF control, OCP and OVP, and Panel Lock, the SPPS305-2KD provides practical control for repeated circuit development and verification work.
