    DC Power Supply Variable, 30V 10A Bench Power Supply with Encoder Coarse & Fine Adjustments Knob, Adjustable Switching Regulated lab Power Supplies with 18W USB & Type-C Quick-Charge

    • Precise encoder knob: HANGELL DC power supply 0-30V 0-10A is different from the ordinary traditional knob, which is adjusted by precision encoder knob, with high precision and strong stability. With coarse adjustment and fine adjustment, the number of digits can be switched by pressing the knob, and the value can be set by rotating the knob. It is more convenient to adjust the required voltage and current.
    • Output switch button: The variable dc power supply is equipped with an output switch button, so you can easily turn on or off the output by pressing the output button. You can check the working status through the indicator light on the display screen. When the output is turned off, the voltage and current data can be adjusted anytime and anywhere, effectively preventing the load equipment from being damaged by forgetting to turn off the output.
    • Short circuit alarm: In order to improve the safety of lab power supply and prolong its service life, we designed a short circuit alarm device for DC power supply. After the OCP function is turned on, if the load equipment is short-circuited in the working process, the variable power supply will automatically stop outputting and send a buzzer to remind the user, protecting the adjustable power supply and the load from being damaged. Bench power supply also has safety protection functions such as overvoltage, overcurrent, overtemperature and overload.

    Hangell DC power supply is very comprehensive in terms of functionality. We have always prioritized the reliability of quality, using a metal body, safe and stable electronic components to ensure the stability and accuracy of the DC power supply, with lower ripple and noise. With multiple security protections at the same time, it will become a good helper for you in laboratory and industrial applications.

    In order to facilitate widespread use by customers in different regions, our DC adjustable power supply adopts a dual input voltage function, with an input voltage selection of 230V/115V. If you are in an area with an input voltage of 110V, you will need to flip the switch to 115V. Choosing the wrong option will affect the user experience of the DC power supply.

    DC POWER SUPPLY

    DC power supply uses encoder knob, which is convenient for setting data. Both voltage and current have coarse and fine adjustment methods.

    • COARSE adjustment-set the value before decimal point.
    • FINE adjustment-set the value after decimal point.

    The setting is faster, which saves complicated operation and is more convenient and accurate than the traditional knob.

    Output enable/disable switch: convenient for adjusting the output status of the power supply at any time. When the DC power is turned on, the default state is not output. When you press the "output" button, the indicator "OUT" in the screen turns green, indicating that the power output is turned on. When you do not need to output, pressing the "output" button again will turn off the output. The output button can prevent us from forgetting to turn off the output and causing load damage.

    OCP short circuit alarm: When the adjustable power supply or load experiences a short circuit, the power supply will automatically stop outputting and emit a buzzing alarm to remind the user. Effectively prevent damage to the variable DC power supply and load.

    Intelligent cooling fan: The cooling fan helps to reduce internal temperature. When the working temperature exceeds 122 ?/50 ?, the cooling fan will intelligently turn on, extending the service life of the equipment.

    Low noise: This bench power supply adopts safe and reliable electronic components and a new circuit design, which will make the noise and ripple of the power supply very low.

    10A fuse box: The back of the benchtop power supply is equipped with a replaceable fuse, providing perfect overload protection and short circuit protection. Ensured the normal operation of the circuit.
