Product Description

Power Supply High school teaching power for School Lab (Physical Instrument)

High school student power:
The power supply for school lab is used for low-voltage AC and DC regulated power supply for high school physics group experiments. There are many adjustable gears for the DC voltage stabilized output. There are 16 output gears for single and double selection. It has good stability and small ripple voltage. Each output has an overload protection function, which can automatically shut down when the output is overloaded.

Product feature and application
This power supply for school lab is mainly used as a low-voltage AC and DC regulated power supply for junior high school and high school physics teaching experiments.

Maintenance and precautions
1. The power supply should be stored in a dry and ventilated place without corrosive gas to prevent the device from being damp, corroded and reduced in insulation.
2. The power supply should be used within the rated load, and overloading is strictly prohibited.
3. When using the pressure regulating switch, it should be gradually changed from low to high to avoid damage to the experimental circuit due to overvoltage or overcurrent.
4. When the instrument is fully loaded and used continuously for a long time, the circuit chip of the instrument may be protected due to overheating. In this case, the load can be reduced or the internal temperature can be lowered before enabling it.
