KUAIQU 0-60V 0-5A 300W DC Test Supply
with CV/CC for Contactor and Relay
Testing SPPS-C605
The KUAIQU SPPS-C605 is a DC Test Supply designed for bench testing compatible DC contactors, relays, electromagnetic coils, and related low-voltage switching components. With a 0-60V adjustable output, up to 5A current, and 300W maximum power, it provides flexible DC supply conditions for coil testing within the rated requirements of the device under test.
For DC Contactor and Relay Testing, technicians and engineers can use the SPPS-C605 to establish the required coil voltage, observe current and power during energization, control output when applying or removing coil power, and compare the electrical behavior of different compatible components. The CV/CC operation, dual-knob encoder adjustment, and Voltage Current Power Display provide practical control and monitoring for laboratory, engineering, repair, and component evaluation work.
Key Features
0-60V Adjustable DC Output for Contactor and Relay Coils
The SPPS-C605 provides adjustable DC output from 0 to 60V, with up to 5A current and 300W maximum power. This range provides flexibility for testing compatible DC contactors, relays, solenoid-operated switching components, and electromagnetic coils with different rated DC input requirements.
Technicians can configure the DC Test Supply according to the rated coil voltage of the component under test rather than relying on a single fixed supply condition.
CV/CC Operation for Different Coil Loads
The SPPS-C605 automatically switches between Constant Voltage and Constant Current operation according to the connected load. This provides flexible DC power for compatible contactor and relay coils with different electrical characteristics.
During testing, users can establish the required supply condition within the rated output range and observe the resulting electrical readings while the coil is energized.
Encoder Adjustment for Controlled Coil Voltage and Current Settings
The dual-knob encoder provides precise adjustment of voltage and current settings. This is useful when testing contactors and relays with different coil specifications or when making controlled changes to the supply condition during component evaluation.
The encoder adjustment also makes it easier to return to a defined test setting when repeating tests on multiple samples.
Voltage Current Power Display During Coil Operation
The 4-digit digital display provides voltage, current, and power readings during operation. These readings allow technicians to observe the electrical condition of the coil while the contactor or relay is being energized.
Changes in current or power can be observed during different test conditions, providing useful electrical information for component comparison, troubleshooting, and verification.
Output Control for Energization and Release Checks
The independent Output Control allows users to prepare the required voltage and current settings before applying power to the contactor or relay coil.
Switching the output on or off provides a convenient way to perform basic energization and release checks, repeated switching tests, and controlled power application without repeatedly changing the configured supply parameters.
Controlled DC Supply for Different Coil Ratings
Contactors and relays are available with different coil voltage and current requirements. The adjustable output of the SPPS-C605 allows users to configure suitable DC supply conditions for compatible components within the 0-60V, 0-5A, and 300W rated output capability.
This flexibility is useful when one test bench needs to accommodate multiple relay or contactor samples with different rated DC coils.
Electrical Behavior Comparison Between Components
The Voltage Current Power Display provides direct electrical readings that can be compared between compatible contactors, relays, or coil samples.
Engineers can observe the supply voltage, current consumption, and power reading for different samples under similar configured conditions as part of basic component evaluation and troubleshooting.
Compact Bench Design for Electromechanical Component Testing
The compact SPPS-C605 is suitable for electronics laboratories, electrical engineering workstations, relay testing benches, repair areas, and component development environments. The temperature-controlled fan supports cooling during operation, while the USB 5V/2A output can provide auxiliary power for compatible USB-powered accessories used around the workstation.
Applications
DC Contactor Coil Testing
Use the SPPS-C605 to provide adjustable DC power to compatible contactor coils and observe their electrical operating condition. Engineers can configure the required coil voltage and monitor voltage, current, and power during the test.
The Output Control can be used to apply and remove coil power during basic energization and release checks.
DC Relay Coil Testing
The DC Test Supply can provide adjustable power for compatible relay coils within the 0-60V, 0-5A, and 300W output range. Users can establish the required coil supply condition and observe the electrical readings while the relay is energized.
This makes the SPPS-C605 suitable for relay evaluation during development, repair, and laboratory testing.
Contactor and Relay Energization Checks
The Output Control provides convenient control of when DC power is applied to the coil. Technicians can configure the required voltage and current first and then activate the output to perform basic energization checks.
The displayed current and power values can be observed during the energization process as part of the electrical evaluation.
Contactor and Relay Release Checks
Removing DC output through the Output Control provides a simple way to perform release checks after the coil has been energized.
This can be useful when repeatedly checking the basic energization and de-energization behavior of compatible contactors and relays during bench evaluation.
Different Coil Voltage Testing
The 0-60V adjustable output allows the SPPS-C605 to accommodate compatible contactors and relays with different rated DC coil voltages.
Technicians can configure the supply according to the component specification and use the same DC Test Supply for different samples within its rated output capability.
Coil Current and Power Observation
The Voltage Current Power Display allows users to observe the electrical values associated with the connected coil during testing.
Current and power readings can be compared between different samples or different test conditions to support basic electrical evaluation and troubleshooting.
Contactor and Relay Sample Comparison
When multiple compatible components need to be evaluated, the SPPS-C605 allows users to establish consistent voltage and current settings and compare the displayed electrical readings between samples.
This can support component selection, incoming inspection, engineering evaluation, and troubleshooting procedures where electrical behavior needs to be compared.
Repeated Energization and De-Energization Testing
The Output Control can be used for repeated power application and removal during basic contactor and relay testing.
Technicians can maintain the configured supply parameters while repeatedly switching the DC output to evaluate the electrical behavior of compatible components across multiple test cycles.
Relay and Contactor Repair Verification
The SPPS-C605 can serve as an adjustable DC Test Supply during repair and post-repair verification of compatible contactors, relays, and coil-driven switching components.
After repair or replacement, technicians can configure the required supply condition, apply DC power, and observe voltage, current, and power readings during the basic operating check.
Electromechanical Component Development Testing
For engineering development, the SPPS-C605 provides adjustable DC power for compatible relay, contactor, and electromagnetic coil evaluation.
The combination of encoder adjustment, CV/CC operation, Output Control, and real-time electrical display allows engineers to establish and repeat defined supply conditions during component development and laboratory testing.
