KUAIQU SPPS-C3010 30V 10A 300W

Adjustable Bench Power Supply with

Output Control for Relay and Solenoid

Testing

The KUAIQU SPPS-C3010 provides adjustable DC power for testing compatible relays, solenoids, electromagnetic coils, and other low-voltage electromechanical components. With a 0-30V output range, up to 10A current, and 300W maximum power, it allows users to establish suitable coil supply conditions while monitoring voltage, current, and power during testing. The encoder adjustment and Output Control make it convenient to configure test parameters, apply power, and repeat relay or solenoid operating checks.

Key Features

Adjustable DC Output for Different Relay and Solenoid Coils

The SPPS-C3010 provides 0-30V adjustable voltage and up to 10A current within a 300W maximum output. This allows engineers and technicians to configure appropriate DC supply conditions for compatible relay coils, solenoid coils, and other electromagnetic components according to their rated requirements.

Output Control for Controlled Coil Testing

The independent Output Control allows the required voltage and current settings to be prepared before power is applied to the device under test. During Relay and Solenoid Testing, users can conveniently switch the DC output on or off when checking coil energization, de-energization, and repeated operating conditions.

Encoder Adjustment for Precise Parameter Setting

The dual-knob encoder provides controlled adjustment of voltage and current settings. This is useful when testing relays and solenoids with different rated coil voltages or when gradually changing the supply setting to observe the electrical response of the connected component.

Voltage, Current and Power Display

The 4-digit digital display provides clear voltage, current, and power readings during testing. Users can observe the electrical conditions of a relay or solenoid coil while power is applied and identify changes in current consumption during different test conditions.

CV/CC Automatic Switching for Electromagnetic Loads

The SPPS-C3010 automatically switches between Constant Voltage and Constant Current operation according to the connected load. This provides flexible DC power for compatible relay, solenoid, and electromagnetic coil testing within the rated output range.

Independent Power and Output Switching

The separate power and output switching design provides convenient control during bench testing. Users can prepare the Adjustable Bench Power Supply before applying output to the relay or solenoid, making repeated connection, replacement, and operating checks more convenient.

Applications

Relay Coil Energization Testing

Use the SPPS-C3010 to provide adjustable DC power to compatible relay coils and observe their electrical operating conditions. Voltage, current, and power readings help users monitor the coil while applying the required supply conditions.

Solenoid Coil Operating Tests

The Adjustable Bench Power Supply can provide controlled DC power for compatible solenoid coils within the 0-30V, 0-10A, and 300W output range. Users can configure the supply according to the solenoid's rated requirements and monitor its electrical response during operation.

Relay and Solenoid Comparison Testing

Different relays and solenoids may require different coil supply conditions. The SPPS-C3010 allows users to adjust voltage and current settings and compare the electrical behavior of compatible components under different test conditions.

Repeated Switching and Functional Checks

The Output Control provides convenient on/off control during repeated relay and solenoid operating checks. It can be used for repeated energization and de-energization tests when evaluating compatible electromechanical components on a laboratory or engineering bench.

All KUAIQU DC power supplies support basic battery charging. For dedicated long-term charging, our patented battery-charging model with independent BATTERY key and full charging protection is highly recommended.

A certain amount of ripple is normal for all switching DC power supplies. Ripple is a small residual AC component superimposed on the DC output and is an inherent characteristic of switching power supply technology. The typical ripple voltage of our power supplies ranges from approximately 100 mV to 300 mV, which is suitable for most general-purpose testing, maintenance, and electronic applications.

A: Minor fluctuations in the last displayed digit are normal and are typically caused by temperature drift within the electronic components. As ambient and internal temperatures change, small variations in the readings may occur. This falls within normal industry tolerances and does not affect the power supply's suitability for everyday electronics work, home repairs, DIY projects, or general testing. For applications requiring extremely high precision and ultra-stable output, a linear DC regulated power supply may be more appropriate.

This is normal and does not indicate a malfunction. The internal capacitors continue to hold a small amount of stored energy after the power is switched off. As the capacitors discharge, the display will gradually turn off, typically within 5–8 seconds.

In CV mode, the power supply maintains a fixed output voltage while the current varies according to the load. In CC mode, the power supply limits the output current to a preset value, automatically reducing voltage if necessary. CC mode is especially useful for battery charging, LED testing, and protecting electronic components.

This is normal behavior. The power supply contains internal filter capacitors that store electrical energy. When the output voltage is reduced, these capacitors require a few seconds to discharge, causing the displayed voltage to decrease more gradually than when increasing the voltage. Q: Why does t

Output ripple refers to small residual AC fluctuations present in the DC output. Lower ripple levels provide cleaner power, which is important when testing sensitive electronics, RF circuits, audio equipment, and precision instruments.

Yes, all DC regulated power supplies manufactured by KUAIQU support battery charging. However, if you mainly intend to charge batteries, I would highly recommend our patented DC power supply specially designed for battery charging. It comes with an exclusive dedicated BATTERY function key, and built-in specialized charging protection functions to safeguard your batteries during the whole charging process..

This is normal behavior. The power supply contains internal filter capacitors that store electrical energy. When the output voltage is reduced, these capacitors require a few seconds to discharge, causing the displayed voltage to decrease more gradually than when increasing the voltage..

This is normal and does not indicate a malfunction. The internal capacitors continue to hold a small amount of stored energy after the power is switched off. As the capacitors discharge, the display will gradually turn off, typically within 5–8 seconds..

This is a common operation issue for adjustable DC power supplies. Please follow the steps below to solve the voltage adjustment failure: Turn the current adjustment knob clockwise moderately to set the unit to constant voltage (C.V) mode; After confirming the power supply enters CV mode, turn the voltage adjustment knob clockwise, then you can freely adjust the output voltage value..

It is recommended to pre-adjust the voltage to around 5V before operation. This step prevents spark generation when connecting short-circuited loads, which effectively avoids safety accidents and other hidden electrical hazards..

A: Our banana plug adopts cross-slot design. If the plug becomes loose, use a screwdriver to slightly pry open the metal slot, which can make the plug clamp tighter and connect more safely..

Some models of our KUAIQU DC regulated power supplies support programmable control. They are equipped with USB, RS232 or RS485 communication interfaces and adopt the Modbus protocol. You can realize remote control easily by using our self-developed PC software. If you need programmable control but are unsure whether a specific model comes with your required communication interface, please feel free to contact us via email: kuaiquinstrument@163.com.
