LS5050C-ESP Datasheet? Max Amps? Polarity?

There is zero info available for the LS5050C-ESP. Not even the polarity of the barrel connector. Is there any tech specs anwhere? How much current can be used with it? I just burned out two of those and I have no idea why. I wired up everything correctly as far as I can see (I found the wiring of the LED side on an Aliexpress listing), but the controllers burned out instantaneous. 24v LED strip, 24v 60w power supply..
