🔥Differences between the PCB boards of other brands' switching power supplies and the KUAIQU SPS-C3010S PCB board

For other brands' PCB boards

1, Small common-mode choke with thin windings, low-spec filter components, only meeting basic EMI requirements with poor anti-interference.

2, Small main transformer with low-grade magnetic core, insufficient power margin, easy to overheat under long-term full load.

3, Only one 880μF-class large capacitor on the high-voltage side, average output filtering, weak ripple suppression and low redundancy.

4, Chaotic PCB layout, no effective isolation between high/low voltage circuits, excessive flying wires/manual connections, irregular traces, poor EMC design and low mass production consistency.

5, Thin PCB traces, weak high-current carrying capacity, high overheating risk at full load.

6, Small heat sinks, crude thermal design, loose component arrangement, easy to overheat under long-term full load and short service life.

PCB Board of KUAIQU SPS-C3010S

1, Large-volume common-mode inductor with thick magnetic core and full windings; higher-spec filter components deliver strong EMI suppression and better input stability.

2, Large main transformer with high-grade magnetic core and thicker windings, providing sufficient power margin to support long-term full-load operation.

3, Multiple large capacitors in parallel (5 high-capacity electrolytic capacitors on high-voltage and output sides combined) offer larger total capacity, excellent ripple suppression, purer output voltage and full design redundancy.

4, Compact and reasonable layout with clear separation between high-voltage and low-voltage circuits; regular and thick copper traces, high proportion of SMD components, automated soldering, mature mass-production design (marked BR300 REV.1.3), ensuring excellent consistency and reliability.

5, Robust traces for high-current paths deliver strong current-carrying capacity, excellent heat control and support for long-term high-load use.

6, Large fan plus rational component arrangement ensures sufficient heat dissipation for high-heat components; complete over-temperature protection guarantees long service life and high reliability.

🔥How to set the output to constant voltage (CV) or constant current (CC) mode

This DC adjustable switching power supply supports automatic constant current (CC) and constant voltage (CV) output, and switches automatically according to the voltage and current required by the load.

As shown in the video, the fan is rated at 12V 0.34A. If we set the power supply to 12V 0.2A—lower than the actual current the fan needs—the unit will enter constant current (CC) mode.When we turn up the current beyond the fan’s required value, the power supply will switch to constant voltage (CV) mode.

In CV mode, the output voltage stays fixed, while the current automatically adjusts to match the load’s needs.In CC mode, the output current remains constant, while the voltage varies according to the load’s voltage requirement.

🔥Main Differences: KUAIQU SPPS-CxxC vs. SPS-CxxS Series

🔥KUAIQU SPS-CxxS DC Power Supply Variable, Adjustable Regulated DC Bench Power Supply with OCP/OVP/Output/Encoder/18W USB-A Type-C Fast Charge, Benchtop Lab Power Supplies with 4-Digit LED Display

🔥【Upgraded OVP/OCP】

Based on the original DC power supply, this new serie DC bench supply improved the Over Voltage Protection (OVP) and Over Current Protection (OCP) and added OVP/OCP button, provides more secure using experience. Activate the OVP/OCP of the adjustable power supply, if the output voltage/current is higher than preset (or short circuit etc.), the DC regulated power supply stops output automatically and sounds beeping alarm, the display flashes OVP/OCP, provides real-time protection for the bench power supply. To turn to general mode, just turn up the voltage/current or disconnect load (when short circuit is detected) and repress the OVP/OCP button

🔥【Output Switch】

Sometimes we need to switch between different voltage or current outputs in experiments or work, but we often forget to turn off the output and causing damage to the load. The adjustable DC power supply OUTPUT switch is designed to solve this problem, just with a single press of the added OUTPUT switch, you can easily turn the output on or off. You don't need to disconnect the load or turn off the power each time, making the variable DC power supply more convenient and efficient to use.

🔥【Precision Encoder】

Unlike ordinary potentiometer knobs, this DC power supply variable features with high precision encoder adjustment knobs that has strong accuracy and stability. With coarse adjustment and fine adjustment, the number of digit can be switched by pressing the knobs, and the value can be set between 0-9 by rotating the knobs, you can set the desired voltage and current on bench supply effortlessly. The required voltage and current can be adjusted without actual output power, which makes this benchtop DC power supply more secure and more energy saving

🔥【18W USB-A/Type-C Fast Charging & Intelligent Cooling Fan】

Complaining about mobile phones or repaired devices not being charged in time? The adjustable switching regulated power supply allows you to avoid this dilemma. The variable power supply is configured with 18W USB-A and Type-C fast charging ports which can quickly charge any USB devices anytime. The adjustable power supply features with intelligent temperature-controlled fan and heat sink for excellent heat dissipation when the working temperature of the switching power supply exceeds 122℉/50℃, greatly reduce working noise and improving the DC regulated power supplies working efficiency and lifespan

🔥【Reliability & Various Applications】

The adjustable DC power supply is built with premium electronic components and reliable circuit designs that include multiple protection functions, such as leakage, grounding terminal, over-voltage, over-current, over-power, over-load, over-temperature, short-circuit protection to ensure stable working performance and prolong the life of the adjustable DC power supply effectively. This benchtop power supply is suitable for battery charging (LiFePO4, lead acid batteries, etc.), electronics repair, anodizing, electrolysis, electroplating, aging test, production line test, DIY, labs, schools, laboratories scientific research and teaching etc
