Here is the specification of an electronic load:

If the load is set in current mode, the current is limited to 25 A.

Nevertheless, if the current is set in resistor mode, I could think that it is only limited by the power (1500 W @ 20°C.)

Suppose we set the resistance to the minimum (10 mΩ.) Does that mean that the current would be equal to 387 A?

$$I = \sqrt{\dfrac{P}{R}}$$

I think that it is not possible.

What is the maximum current? Is it a bit higher than 25 A or is it 25 A? I was thinking that it was possible to find an "SOA" of the electronic load into the datasheet, but I did not find it.

The voltage and currents on the load have to be constrained within all limits simultaneously: -

  • Maximum current of 25 amps
  • Maximum voltage of 750 volts
  • Maximum product of voltage and current of 2400 watts (e.g. 10 amps and 240 volts)

I was thinking that it was possible to find an "SOA" of the electronic load into the datasheet, but I did not find it.

You can make an SOA curve from the above three bullet points: -
