Still didn't look like a Jebao one to me so I kept looking. Have you ever owned a Curve skimmer? The model number brought attention to it. Although the amps seems really low for a skimmer pump. They would normally be 5amps
My Cross Flow CP-150 came with the same, (24 volts / 1.5 amp) power supply.
I know, the CP-150 supposed to be 55 watts and this PSU is only 36 wats max but this is what it came with in the brand new, sealed, original packaging.
