DC actuators use a capacitor to provide inrush current high enough to pull the plunger of an AC solenoid up and maintain about 2.5 volts DC to provide holding current if I'm not mistaken. The problem is that they're battery eaters. I'm interested in your solar theory of why one would use an AC solenoid rather than a DC solenoid and what the advantage would be?
Bench testing an Armada pro48 actuator shows me max of 15.3 volts AC and a max 31.7 DC and .030 mA load.
