I really like the PowerSwitch Tail for AC loads because it is a packaged unit. Quick, easy, safe, looks good. And switched with 3vdc.
Problem is I need a Normally-Closed DC Relay switched with 3vdc, rated for say 5 amps and 18volts. Enough to drive a fluid circulator pump by a small solar panel. Ideally it would also be a clean packaged unit suitable for a mechanical room.
Anyone know of options?
