Portable heaters often get dropped, kicked, damp, etc. Compared to that, this was the easy life, it's still working.tom91 wrote: ↑Mon Jan 06, 2020 10:54 pmHow did this last in the car?

Prices vary wildly for the EV200HAANA on eBay from between the $40 ones from Isreal in the link above to the Mouser/Farnell items for €160 to a couple more on eBay for €300!. Is it just worth the peace of mind buying new from the suppliers or are they that robust, used ones are good for 380v from a Leaf pack?arber333 wrote: ↑Thu Oct 31, 2019 12:41 pm I consider this each DIY preference.
Mine is Tyco Kilovac contactor EV200HAANA.
It is capable of braking 900Vdc at 500A! Inside it is nitrogen (inert gas) filled so arc doesnt form and contacts are silver coated.

Well i have bought 3 EV200 from israel. They are used for military equipmment power supply etc...Cookie6000 wrote: ↑Thu Jan 30, 2020 4:26 pm

EberspaecherHeater.c
The heater communicates using J1939 protocol. It has to be "woken up" one time with a 0x100 message and then
must see a "keep alive" to stay active, which is the 0x621 message. The message repetition rate is between
25 and 100ms intervals.
The Eberspacher CAN version will work when used with a 33.33Kb SWCAN. The data below is the minimum required
to turn on the heater. It will operate at approximately 33% of full power. To command higher power, increase
the value of message 0x1072099 byte 1 (it begins with byte 0) which is 3E below.
Full power is applied when 85 is used as the value for byte 1. The power will vary based upon inlet
temperature as the PTC elements increase the resistance with higher temperature.

I can help you with that. I managed to heat up the heater more by accident and i suspect i damaged it because it didnt had any coolant inside.xp677 wrote: ↑Sat Feb 01, 2020 12:14 pm I don't know which orange wire is + and which is -, this is a problem for me as I don't have a connector on the end of my wires, so can't look it up!
If someone is able to tell me which wire is which, that would be great. Mine do not have red/black bands on them.
If the power section is anything like the Leaf heater linked above, then polarity will matter.
Well, the only bad side is they won't prevent electric arc at higher voltage when disconnect, but it need some malfunction to happen in invertor while under load.SciroccoEV wrote: ↑Thu Feb 06, 2020 6:19 pm Those contactors are only rated for 27v on the switching contacts. Most likely they'd be OK up to 48v nominal, but I wouldn't use them in a high voltage system.
A "Malfunction" is exactly when you need those ratings!konstantin8818 wrote: ↑Fri Feb 07, 2020 8:08 am Well, the only bad side is they won't prevent electric arc at higher voltage when disconnect, but it need some malfunction to happen in invertor while under load.
And that is why I also got HV line kill switch=) And fuse rated at 400A. Just in case.
