Voltage 15V and current 2A

Hello! And what is the current? Constant or variable?
According to PUE 1.7.53
Protection against indirect contact should be performed in all cases if the voltage in the electrical installation exceeds 50 V AC and 120 V DC. In rooms with increased danger, especially dangerous and in outdoor installations, protection against indirect contact may be required for more low voltages such as 25 VAC and 60 VDC or 12 VAC and 30 VDC if required chapters of the PUE.
Protection against direct contact is not required if the electrical equipment is in the potential equalization area, and the highest operating voltage does not exceed 25 VAC or 60 VDC in non-hazardous locations and 6 VAC or 15 VDC in all cases.
Note. Hereinafter in the chapter, AC voltage refers to the rms value of the AC voltage; DC voltage - DC voltage or rectified current with a ripple content of not more than 10% of the rms value.

If we talk about alternating current, then values ​​greater than 100 mA are deadly. But more importantly, for what purpose are you asking your question? If you are wondering - can a power supply unit in which such characteristics are indicated harm a person? If I understood your question correctly, then the answer is that such a power supply is not dangerous, and the current flowing through the human body is determined by Ohm's law and with such a voltage there will be no current of 2 A.
