Smart Electricity Meter Testing DC Power Supply with Dual Independent Outputs
The KUAIQU SPPS305-2KD is an 8-Group Memory DC Power Supply designed to provide adjustable DC power for smart electricity meter circuits, metering control boards, and related electronic modules. 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 compatible meter circuits and electronic test setups.
Smart Electricity Meter Testing may involve different power requirements for metering circuits, display sections, control boards, and related electronic components. The SPPS305-2KD supports Independent, Series, and Parallel output modes, together with Negative-0-Positive Voltage output, providing flexible DC power configurations for meter development and laboratory evaluation. 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.
Key Features
Dual Independent Outputs for Smart Electricity Meter Testing
The SPPS305-2KD provides two independent DC output channels, with each channel supporting 0-30V, 0-5A, and 150W output.
For Smart Electricity Meter Testing, the two channels can be adjusted independently to supply separate DC power conditions to compatible metering circuits, control boards, or related electronic modules. This is useful when a test setup requires different adjustable power settings for separate circuit sections.
Negative-0-Positive Voltage Output for Flexible Circuit Power Supply
The SPPS305-2KD supports Negative Voltage - 0 - Positive Voltage output mode, providing a flexible power configuration for compatible electronic circuits that require different voltage polarities.
This function can be useful when evaluating smart meter control circuits or related electronic modules that require positive and negative supply conditions. Users can configure the output according to the voltage requirements of the connected circuit within the supported operating range.
Independent, Series, and Parallel Output Modes
The SPPS305-2KD supports Independent, Series, and Parallel output configurations for different Smart Electricity Meter 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 meter circuits or related electronic modules require different voltage or current conditions.
Precision Encoder Adjustment
The SPPS305-2KD uses precision encoder adjustment for voltage and current control.
During Smart Electricity Meter Testing, users can adjust the DC power conditions according to the requirements of the connected circuit or 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 Meter Circuit Testing
The SPPS305-2KD provides Over Current Protection (OCP) and Over Voltage Protection (OVP).
During smart meter circuit power-up and 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 Smart Electricity Meter 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 meter circuit development and evaluation, the Panel Lock function helps prevent unintended changes to configured settings. The buzzer provides operating feedback during use.
Applications
Smart Electricity Meter Circuit Power Supply Testing
The SPPS305-2KD provides adjustable DC power for compatible smart electricity meter circuits during laboratory development and evaluation. Users can set the output voltage and current according to the power requirements of the circuit under test.
Metering Control Board Development
The dual independent outputs can supply power to compatible metering control boards and related electronic circuits during prototype development and circuit debugging.
Each output channel can be adjusted separately when different circuit sections require individual DC power conditions.
Smart Meter Display and Electronic Module Testing
The adjustable DC outputs can provide power to compatible display sections, electronic control modules, and related circuit assemblies during development and functional evaluation.
Independent, Series, and Parallel modes allow users to select suitable output configurations according to the voltage and current requirements of the connected equipment.
Repeated Smart Meter Power-Up Testing
For repeated power-up and evaluation procedures, the 8-group memory function allows users to store and recall commonly used output settings for Independent, Series, and Parallel modes.
Combined with independent Output ON/OFF control, encoder adjustment, OCP and OVP protection, and Panel Lock, the SPPS305-2KD provides practical power control for repeated smart meter circuit evaluation.
