KUAIQU SPPS-C305 30V 5A 150W DC Test
Supply and DC Power Source with CV/CC
for Electronic Repair
The KUAIQU SPPS-C305 is a 30V 5A 150W DC Test Supply and DC Power Source designed for electronics repair, troubleshooting, and bench diagnostics. During repair work, a controllable DC source can be used to power compatible circuits and devices while technicians observe voltage, current, and power conditions. The SPPS-C305 combines adjustable DC output, CV/CC operation, encoder adjustment, and independent output control to support practical repair procedures and repeated fault-checking tasks.
Key Features
Controlled DC Power for Repair Work
The SPPS-C305 provides 0-30V adjustable voltage, 0-5A adjustable current, and up to 150W output power. This allows technicians to establish an appropriate DC supply condition for compatible electronic devices and circuits during repair and troubleshooting, within the rated operating range of the power supply.
Monitor Current and Power During Troubleshooting
The 4-digit display provides Voltage, Current, and Power Display information while the connected device is operating. During troubleshooting, observing current consumption and power changes can provide useful electrical information when checking a device under different operating conditions.
CV/CC for Different Repair Conditions
CV/CC automatic switching allows the DC Test Supply to operate according to the connected load condition. This can be useful when troubleshooting electronic circuits where the load behavior changes during startup, operation, or testing.
Encoder Adjustment for Precise Settings
The dual-knob encoder provides direct adjustment of voltage and current settings. Technicians can make controlled changes to the supply parameters during a troubleshooting procedure instead of relying on coarse adjustment, making it easier to test a device under different DC input conditions.
Independent Output Control
The independent output switch provides convenient control over DC power delivery during repair. Technicians can prepare the required settings, switch the output on for testing, and turn the output off when checking connections or making changes to the device under repair.
Compact DC Power Source for Repair Benches
The compact design makes the SPPS-C305 suitable for electronics repair benches, service areas, laboratories, and development workstations. Its USB 5V/2A output can also provide power for compatible USB-powered equipment used alongside repair and troubleshooting work.
Applications
Electronic Device Repair
The SPPS-C305 can be used as a DC Power Source when servicing compatible electronic devices that require an adjustable DC supply within the 0-30V, 0-5A, and 150W rated range. Technicians can set the required supply conditions and observe the electrical response during repair.
Fault Finding and Troubleshooting
During troubleshooting, changes in current and power can provide useful information about the operating condition of a connected circuit. The Voltage Current Power Display allows technicians to observe these values directly while checking a device under test.
Board-Level Repair and Circuit Checking
For compatible low-voltage circuit boards and electronic assemblies, the DC Test Supply can provide adjustable power during bench checking. Technicians can control the output, observe electrical readings, and repeat tests after inspecting or adjusting the circuit.
Repair Verification
After a repair or component replacement, the SPPS-C305 can be used to reapply the required DC supply and observe the device's operating conditions. The independent output switch makes repeated power-on and power-off checks convenient during final verification.
