Output switch control In the process of using the variable power supply, you can press the output button at any time to turn on or turn off the output of the power supply. This design can prevent you from damaging the device because you forget to disconnect the output. Effectively improve the efficiency of your experiment.

The DC power supply we tested is versatile and effective at powering a wide range of loads. It offers three output modes: DC-out, AC-out, and USB-out. The DC-out mode is for powering devices that require 24V DC power. The AC-out mode is for powering devices that require 110V AC power. The USB-out mode is for powering devices that require 5V DC power. The power supply we tested has a built-in selector switch. This switch enables you to choose one of the three output modes. The selector switch has three positions: DC-out, AC-out, and USB-out. The three output modes are convenient for powering multiple devices. The power supply we tested has a 4-digit LED display. The bright LED display enables you to use the power supply in a dim environment. And the display brightness is adjustable. The power supply we tested is more accurate and convenient than traditional knobs. When you press the encoder knob of the power supply to switch between each digit, and then turn the knob to set each digit in the range of 0-9, you can efficiently and accurately set the voltage and current data you need. The power supply we tested has short-circuit protection. When the load equipment fails and short-circuits, the adjustable power supply will emit a buzzer alarm. The power supply we tested has multiple protections, such as grounding wire, leakage protection, thermal protection, voltage overload, power supply overload, etc.
