Blue Sea 7620 ML-Series Automatic Charging Relay (Magnetic Latch) 12VDC

all right so in this video here we're going to look at the blue c7622 automatic charging sensing relay so this closes when it sees a charging voltage on a terminal they have a few different models of this 24 volt and some are manual only some have a plunger on them like this one so you can close it by hand if you have a need to do that and you can also lock it out so i've got two of them here so take a look at them how they work with the switch connected to them as well as with the switch disconnected you can use it both ways so i've got the manual here and a little diagram of how i'm going to use it in my camper so when you buy these they come just in a plastic package if you buy them in the bulk pack they don't come with the uh switch with them so basically it does a few different things it's the same manual for all the models you can see the different voltages and times that it needs
