[RE-wrenches] Rapid Shutdown

[Starlight Solar Power Systems]

James,

Sorry for the confusion: these are not Midnite parts. These are Gigavac solenoids. They come with high efficiency coils, 2.8 Watts holding for the 48 Vdc, 2.9 Watts for the 800 Vdc. We are using quite a few each month so I buy at 50+ piece volume pricing. see attachments.

Larry,

Any details on these $120 solenoids? Are they latching coil, or will we be burning another 5 to 20 watts per device to keep them closed?

I did a quick search of Midnite's site and got no relevant hits with relay, solenoid, or contactor as search terms.

Thanks,
