I have this generator, https://joy-it.net/en/products/JT-JDS2915 but it doesn’t say in the manual what maximum current this thing can provide.

It does say ‘output impedance = 50 Ohm’. is that what i need to use to determine maximum available current?

And can i assume that the 50 ohm acts as a short-circuit protection. After all, 10V / 50 Ohm = 0.2 A
