KUAIQU High Precision Adjustable Lab Power Supply, 30V 60V 120V DC Regulated Power Supply With OCP OVP OTP OLP, 24 Hours Full Load Output, Enough Power, Stable C.V

🔥Our adjustable DC switching power supplies (models SPS‑C3010S, SPS‑C605S, SPS‑C1203S and SPS‑C305S) undergo burn‑in testing with different load resistors before shipment, ensuring customers receive only qualified products.

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

It can be seen that our KUAIQU SPS-C3010S outperforms other low-cost power supplies in terms of EMI input filtering, main power transformer, filter capacitor configuration, PCB layout and craftsmanship, high-current path design, heat dissipation and 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.

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
