POWER: Pumps operate with low energy (only 14 watts), low voltage (12-24 volt) motors, powered with compatible transformers with world wide primary voltages available (100 VAC, 120 VAC, 230 VAC). Transformers are optional and must be ordered in addition to the pump.
This is what I found at the link above. Low voltage it appears is 12-24 VAC and not DC
. The word transformer says that it is AC
by all practices that I know of. If it would have said Power Supply, then I would assume DC
instead of AC
. I would check with the mfgr for the exact type of current.
Now if you are using the PSW switch they are showing. I believe based on the information that it is a normally closed switch and works from Pressure of the water going through. A switch if it is mechanical will switch any "rated" voltage based on the amount of "rated" current the switch can handle. Again I would contact the mfgr for the specs on the switch.
