- 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.
- High-precision 4-digit LED display screen: The laboratory DC benchtop power supply is a professional laboratory power supply regulating device with high resolution of 0.01V and 0.001A, providing more accurate voltage and current readings. Constant voltage (C.V)/constant current (C.C.) mode automatically switches with the change of load. You can see the working status indicator on the display. It is clearly visible even under the condition of insufficient light.
- Packaging and after-sales service: The package includes: 1 x variable DC power supply, 1 x input power cord, 1 x output power cord, 1 x user manual. We provide lifelong technical support. If you have any question, please feel free to contact us.
