DC Power Supply Variable, 30V 20A Bench Power Supply with Encoder knob, Adjustable Switching Power Supply with OCP Switch, Variable Power Supply with Output Enable /Disable Button

Features

• High Precision Encoder Knob: Unlike the common potentiometer knobs on the market, the benchtop DC power supply has a precise encoder knob that set the data directly rather than adjusting it. You can easily press the knob to switch each digit and set the desired voltage or current more accurately
• Output Switch: The variable DC power supply has an output switch favored by the majority of buyers. No need to short-circuit the positive and negative terminals; you can set the voltage and current data directly. The output button prevents us from forgetting to turn off the output and damaging the load by simply pressing the output switch button to turn on or off the power output, thus improving the safety and convenience of our work
• OCP Short Circuit Alarm: When a short circuit occurs in the bench power supply or load during use, the power supply will automatically stop output and emit an alarm sound to alert the user. This effectively prevents damage to the adjustable power supply and load. Built in OVP over-voltage protection, OCP (over-current protection), OPP (overload protection), OTP (over-temperature protection), the protection function is perfect and reliable, protecting the staff to work more safely and efficiently
• High Power 4-digit Display: The accuracy of DC power supply is stable and continuously adjustable. It can be easily adjusted between 0-30V and 0-20A. The constant voltage (C.V.) and constant current (C.C.) modes can be automatically converted, and displayed in 4 digits. The original chip is used inside, with stable and reliable performance
• Packing List: 1*lab power supply, 1*output power cord, 1*input power cord and a user manual. We provide technical support.
