🔥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.

The Difference Between SPS-CxxS and SPPS-CxxC

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: 】We care more than you expect. 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
🔥【Mute Function: 】The DC power supply features with encoder knob adjustment beeping sound by default, helps you know the real-time adjustment progress of bench power supply. Of course, we know your concern that sometimes you find the beeping sound of benchtop power supply is annoying. Take it easy, the DC power supply has option to mute the beeping sound, just press and hold the V-FINE encoder knob (the second knob) for 5 seconds, a "bi" sound will remind you the DC power supply is mute. To reactivate the beeping sound, press and hold the V-FINE encoder knob for 5 seconds again or turn off the power supply and restart
🔥【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









DC Power Supply Variable 30V 10A, 300W Encoder Adjustable 6V 12V 24V LiFePO4 Lithium Ion etc. Battery Charger Regulated Lab Bench Power Supply Output Switch/OCP Function/Quick Charge Port
🔥DC power supply Adopts the “reverse polarity protection” principle, has added a charging prompt indicator light, providing reverse connection protection and alerts. Press the "Battery" button, the indicator light on the panel will light up. When it is not correctly connected or not connected to the battery that needs to be charged, the "battery" button will display a yellow light flashing, and the "output" button cannot be pressed. When the "battery" button displays a yellow light and stops flashing, it indicates normal charging. When the "battery" button displays a green light, After charging, Automatic output disconnection when charging is complete
🔥Multi protection, Fast charging and Displaying Charging Ampere-hour: The Bench power supply has a maximum rated voltage of 30V, which can charge your 6V/12V/24V battery. With a maximum rated current of 10A, it can bring a maximum power output of 300W, quickly replenishing your battery's power. It also adds multiple protection functions such as over temperature protection, over current protection, and short circuit protection,and in “Battery” mode, the actual charging ampere-hour is shown on the display (green light lighting under the Ah character), allowing you to charge with more peace of mind
🔥Encoder adjustment, output switch: The DC power supply adopts encoder adjustment, which can be precise to 0.01V and 0.001A, ensuring the most accurate adjustment of data. In order to facilitate use after adjustment is completed, we have added an output switch, which will only output power when the output switch is on, making your use more reassuring
🔥New update of OCP: DC power supply improved the OCP function and added the "OCP" button. When using the DC power supply when your after pressing the "OCP" button, If there is a short circuit in the DC power supply, the LED screen automatically switches to OCP, stops the DC power supply output, protects the DC power supply, Disconnect the short-circuited load and press the "OCP" button again to resume normal use,and provides a more secure user experience
