Ambient Add a Relay kit
Sometimes one relay with the AMB-RAY Kit just won't do the job, Systems could draw more amps than one relay can handle. Or maybe you want to control both the DC and AC circuits as with our Model M3600 heat panel, then just add a relay. Just wire the coil control leads of another relay or more, in parallel to the first one as it is controlled by the electronic ambient sensor switch. When it activates the first one, all other relays will activate at the same time, closing the separate contacts of each relay, and powering "on" whatever is attached to them. Specs: Coil - 12VDC, Contacts - 30A 120/277 VAC, 20A 28 VDC
Price: $ 18.73 USD
Outside temperature must be at least 50°F (10°C) when applying tank, pipe and elbow heaters.
CAUTION
If you are adding to or retrofitting your RV with UltraHeat heaters, especially if your RV is more than three (3) years old, you may want to check first with an RV Dealer to make sure your on-board Power Converter has room for additional circuitry usage or, to determine if you need an additional Power Converter added to your RV or if you need to upgrade to a larger capacity Power Converter on your RV.
