Physics Experiment Student Power Supply Student Power Supply Analyzer Physics Experiment Student Power Supply Measurement Instrument

Physics teaching experimental equipmentModel: HG19-J1202-3C

The student power supply in the physics laboratory is installed on each student experimental platform, and its working power supply voltage (mains) and the voltage values of AC voltage output and DC voltage stabilization output are controlled by the central console.

Physics teaching experimental equipmentConstruction characteristics:

1. Power switch:

The power switch of the student power supply is turned to "power on" to connect the entire machine power supply, and the power indicator light "PE" lights up. When the switch is turned to the opposite position, the power is turned off.

2. Communication output:

The low-voltage AC output interface of the student power supply can be controlled and adjusted by the central console with a voltage value between 2-16V.

3. DC stabilized output:

The DC regulated voltage output interface of the student power supply, where "+" is the positive pole of the output voltage and "-" is the negative pole. The voltage value of this interface can be controlled and adjusted by the central console between 2 and 16V.

4. DC voltage fine adjustment:

The DC stabilized voltage output voltage fine-tuning controller of the student power supply can adjust the output voltage value of the DC stabilized voltage within ± 1V.

5、OL：

The AC output overload indicator light of J102-3C student power supply will light up when the AC output is overloaded, and the power supply will automatically cut off the AC current output. At this point, turn off the power switch, cut off the load, restart the power switch, and the power will automatically resume normal operation. The DC stabilized output of the student power supply is designed with fully automatic overload protection function, which means that when an overload occurs, the interface automatically stops voltage output, and when the overload load is cut off, the interface automatically resumes voltage output.

6. DC ammeter A: The "A" meter installed on the student power panel is a DC ammeter, divided into 0-3A and 0-0.6A levels. On the "Measurement Input" terminal, "0.6A" is used for input in the range of 0 to 0.6A, and "3A" is used for input in the range of 0 to 3A. The negative pole of the electric meter is represented by '-'.

7. DC voltmeter V: The "V" meter installed on the student power panel is a DC voltmeter, divided into 0-3V and 0-15V levels. The "3V" terminal on the "measurement input" is in the 0-3V range, and the "15V" terminal is in the 0-15V range. - "is the negative pole.

8. Sensitive ammeter G: The "G" meter installed on the student power panel is a sensitive ammeter with a range of ± 300 μ A.
