1.5 V, up to 1 A... That's very little power, barely enough for a preamplifier.
I'm confused as to what this was used for. There are AM travelers' information stations at 1610 kHz in the US so the unit would be installed in a vehicle but then it is no problem to use a separate power cable or a 3-wire one because it's just a few meters at most. And the frequency is within the MW band so it can be received by any car's radio anyway, no need for a separate device.
Edit: It says "1-60 MHz", not "1.60 MHz", which I couldn't make out because of the low resolution. That makes it way more versatile.
I have seen Bias Tee injectors for up to 50v@1.5A, thats enough for a decent output booster. But yes in reality 99% of those where used for preamps in analog TV/Radio Rx
