This is a 12VDC 1/2” throw 8 watt continuous duty push type solenoid. It is going to push up an object and keep it lifted permantently except for occasions where it turns off for a minute at a time which would be once a day or maybe not at all for months. I would assume that a 1amp supply is more than sufficient. It does get hot when on. Does anyone have experience with solenoids? My question is how to get the longest lifespan from both the device and the power supply. I can provide a separate power supply for this. The Prop turns on a logic level n mosfet that is rated far above 1 amp. Just looking for advice on whether to use some much higher rated PS for longer life. Also does continuous heat mean this thing fails at some point.
