I read that this unit can only handle 3.2 amps per switch, so my question is, if using a relay to connect to a pair of Hella 4000 100W lights will the capacity of the 4200 controller be exceeded?
Thanks.
Relays typically only use less than a .25 amp, so if you are using relays to switch the high current load, the controller will have no problem handling switching the relays.
It's not quite as polished as the 4200 Mini but it includes relays that handle a lot more amperage. I've been looking at those two products for my own electrical projects but I haven't purchased or used either so I can't comment on quality. The 30 Amp circuit should be fine to handle a pair of 100W lights though.
