The KUAIQU SPS305C is a 30V 5A DC power supply with battery charging function, designed for battery charging, charging process monitoring, battery-related testing, electronics service, and laboratory applications. With a maximum output of 0–30V, 0–5A, and 150W, the SPS305C provides adjustable DC power for compatible rechargeable batteries and electronic devices.
The dedicated battery charging function allows users to monitor the charging process through the built-in digital display.
The SPS305C displays:
Output voltage
Charging current
Charging power
Accumulated charged amount in Ah
Battery charging status
Output status
The Ah display provides real-time information about the accumulated amount of charge delivered during the charging process, making it useful for observing charging progress and comparing charging conditions during battery-related testing.
This combination of adjustable DC output and real-time charging information makes the SPS305C suitable for Battery Charging & Capacity Monitoring, battery service, electronics laboratories, and charging process evaluation.
The SPS305C provides a 0–30V adjustable output voltage and 0–5A adjustable output current, with a maximum output power of 150W.
The adjustable output allows users to set appropriate voltage and current parameters according to the requirements of compatible rechargeable batteries and connected electronic equipment.
The SPS305C supports:
0–30V adjustable output voltage
0–5A adjustable output current
150W maximum output power
10mV voltage setting resolution
1mA current setting resolution
10mV voltage readback resolution
1mA current readback resolution
Real-time voltage, current, power and Ah display
The precise adjustment capability makes the SPS305C suitable for controlled battery charging and electronics testing where users need to monitor charging voltage, current, and accumulated charge.
The SPS305C is equipped with a dedicated battery charging function for compatible rechargeable batteries.
When the battery charging function is activated, the power supply provides charging-related status information through the front-panel display and indicators.
The battery charging function supports:
Battery charging mode
Charging status indication
Accumulated charged amount display in Ah
Reverse polarity protection
Overcharge protection
Automatic output shutdown after the battery is fully charged
This makes the SPS305C more suitable for battery charging applications than a standard adjustable DC power supply when users need to monitor the charging process and accumulated charge.
The SPS305C provides reverse polarity protection during battery charging.
Incorrect battery connection can cause damage or abnormal charging conditions. The battery charging function is designed to identify incorrect connection conditions and provide protection against damage caused by reverse polarity.
This function is particularly useful for:
Rechargeable battery charging
Battery service and maintenance
Battery-related laboratory experiments
Electronics repair
Charging process verification
Battery charging workstations
The battery charging indicator provides a visual indication of the connection and charging status.
The SPS305C provides an OCP (Over Current Protection) function to help protect the power supply and connected equipment when excessive current conditions occur.
During battery charging or electronics testing, abnormal loads or incorrect parameter settings may cause excessive current. The OCP function helps provide additional protection under these conditions.
The dedicated battery charging function provides overcharge protection.
When the battery reaches full charge, the SPS305C can automatically turn off the output to help prevent continued charging.
This function is useful for charging applications where users need additional protection against prolonged charging after the battery reaches its charging limit.
The independent OUTPUT control allows users to set voltage and current parameters before applying output power to the connected battery or electronic device.
This helps reduce the possibility of applying an unintended output condition during battery connection and charging setup.
The SPS305C provides a digital display for monitoring charging-related parameters during operation.
Users can observe:
Voltage
Current
Power
Ah
Charging status
Output status
The real-time Ah display is particularly useful for monitoring the accumulated amount of charge delivered during a charging session.
Instead of requiring a separate charge-amount display, the SPS305C allows users to directly observe the accumulated Ah value from the front panel while charging.
This is useful for:
Charging process observation
Battery charging comparison
Battery service
Laboratory charging experiments
Charging parameter verification
Battery-related electronics testing
The SPS305C uses encoder controls for voltage and current adjustment.
The encoder adjustment system allows users to conveniently set the required charging voltage and current parameters while performing battery charging or electronics testing.
With:
10mV voltage setting resolution
1mA current setting resolution
users can make relatively fine adjustments to charging parameters according to the requirements of the connected application.
The SPS305C provides low-ripple DC output for battery charging and electronics testing.
Its voltage ripple is specified at:
≤60mVp-p
≤10mVrms
The current ripple is:
≤10mArms
Stable DC output is useful when the power supply is used not only for battery charging but also for powering and testing battery-related electronic circuits and modules.
In addition to the adjustable DC output, the SPS305C provides USB-A and USB-C charging ports for compatible USB devices.
The USB-A output supports:
PE1.1/2.0
Apple
BC1.2
AFC
FCP
QC2.0/QC3.0
The USB-C output supports:
PE1.1/2.0
Apple
BC1.2
AFC
FCP
QC2.0/QC3.0
PD3.0
PPS
The USB charging ports provide additional convenience for charging and testing compatible portable electronic devices alongside the main DC power supply.
The SPS305C combines a 0–30V / 0–5A adjustable output with a maximum power rating of 150W, making it suitable for battery charging and electronics testing applications requiring adjustable DC power.
Its compact design measures approximately 22 × 8.5 × 15.5 cm and weighs about 1.2 kg, making it suitable for desktop workstations, electronics laboratories, repair benches, and battery testing environments.
The SPS305C combines:
Adjustable 0–30V output
Adjustable 0–5A output
150W maximum power
Battery charging function
Real-time Ah display
