KUAIQU SPS-C305S - 30V 5A Adjustable DC Power Supply Variable Short Killer USB Quick Charge Output Switch for Mobile Repair, Solar panel and Aging tests

English Manual

Key Features:

• Enhanced OVP/OCP Protection
  Upgraded Over Voltage Protection (OVP) and Over Current Protection (OCP) with a dedicated control button.When output voltage/current exceeds preset levels or a short circuit happens, the power supply automatically stops output, triggers a beeping alarm, and the display flashes "OVP/OCP" for real - time protection. To return to general mode, increase voltage/current or disconnect the load (if short - circuited) and press the OVP/OCP button again.
• Convenient Output Switch
  Specially designed to solve the problem of load damage caused by forgetting to turn off output when switching between different voltage or current settings during experiments or work. Just a single press of the added OUTPUT switch lets you easily turn the output on or off. There's no need to disconnect the load or turn off the power supply each time, making operation more convenient and efficient.
• High Precision Encoder
  Features high - precision encoder adjustment knobs (unlike ordinary potentiometer knobs) with strong accuracy and stability. It supports coarse adjustment and fine adjustment. You can switch the digit number by pressing the knobs, and set values between 0 - 9 by rotating them, allowing effortless setting of desired voltage and current. Adjustments can be made without actual power output, ensuring safety and energy saving.
• Mute Function
  By default, the encoder knob adjustment produces a beeping sound to indicate real - time adjustment progress of the power supply. If the beeping is annoying, press and hold the V - FINE encoder knob (the second knob) for 5 seconds; a "bi" sound will confirm muting. To reactivate the beeping, press and hold the V - FINE knob for 5 seconds again or turn off and restart the power supply.
• 18W USB - A/Type - C Fast Charging
  Equipped with 18W USB - A and Type - C fast charging ports. These ports support multiple fast - charging protocols including PE1.1/2.0, Apple, BC1.2, AFC, FCP, QC2.0/QC3.0, and PD3.0, enabling quick charging of any USB devices at any time and avoiding the dilemma of devices not being charged in time.
• Intelligent Cooling System
  Comes with an intelligent temperature - controlled fan and heat sink. When the working temperature of the switching power supply exceeds 122℉/50℃, the fan activates for excellent heat dissipation. This greatly reduces working noise and improves the working efficiency and lifespan of the DC regulated power supply.
