Review: Have bought 100’s of these - I have used 100’s of these . Work as they should , highly recommend
Review: Wanted a 24V signal voltage to control a 12V load voltage and this works perfectly. - This is for an off-grid cabin where the solar array and battery bank are at 24V but we step down the voltage to 12V using a buck converter and that is what the cabin runs on. We do not run an inverter. Running the core at 24V decreases losses and wire gauge requirements at that core, and also maintains a constant 12.3 volts throughout the cabin regardless of battery state. This approach works well for a small cabin and we don't have all of the inverter loss. (We can run a 680 sq ft cabin on just 400 watts of solar). I know this is not typical, but it has worked well for us for almost a decade now and has some advantages; when almost all of your loads are eventually DC (lights, devices, stereo, etc) it always seemed silly to invert to AC and convert it all back to DC. (we not have large appliances, because.....cabin, not vacation home. No microwave, instead just stove) I wanted a relay in order to have a remote power switch for the whole cabin that is in series with the load terminals on the charge controller, which has a low voltage automatic cutoff for battery protection, but that relay had to be able to handle a nominal 24V at the coil and is actually switching a 12V load. I also had to handle 30 amps @ 12V and wanted a lot of headroom. Yes, our entire cabin draws less than 360 watts peak, and we have a generator for the rare times when we need it for tools or other high loads or for emergency battery charging. We go months without using the generator. A prior cheap relay rated to 30amps got very hot and proved not to be durable. This is a sturdy relay with heavy terminals and never is warm to the touch. Thank you desertcart, for having all of the oddball parts that I would not know where to get otherwise.

## Features

- Our coil power is 1.8W, and the coil resistance is 320 ohms. It is more reliable than 2.4W (240 ohms) and 4.8W (120 ohms) relays on the market
- Large capacity, high current carrying capacity, heavy-duty make/break relay. But never go beyond its capabilities, try to stay 10 to 15% below what the rate is for
- Rated voltage: 24vdc; Pickup voltage: 16v; Dropout voltage: 2.4v
- The size of the round stud terminals: M6/6mm
- Ideal for split charging or any vehicle needing a high power relay
