Hi
i guess im just trying to stop any of the electronics from frying. MY THOUGHT is that if i put relays in the switches( realize a relay is a low voltage switch) then it MAY stop the electronics getting zapped by to much V or Amps when switched on. Maybe im not heading in the right direction.
On my unit i have a 200W geared motor with a 60 Amp fwd-rev-speed controller
, a 120w geared motor with the 2 proximity switches with the 30A speed-reversing controller
and 10A linear actuator.
Non of these will be run simultaneously they will go in sequence so the current draw is lower.
the whole units in the boot of the vehicle so i imagined running a fairly decent sized awg feed direct from battery to the boot and feed of a contact there . ( lessening power drop)
Nothing runs for more than 40 secs at a time either...
being overly cautious perhaps but this is a prototype and i cant-dont want weak points that could cause returns -claims etc.
at the moment the battery is on the floor 1m away from the electronics but obviously when installed it would be feed off the car battery ( with motor running) which gives slightly higher V. and could possibly cause problems?? ( or not)
Thats really where i am. it will probably fine with a few inline fuses but i dont know .During trials ive never over stressed any motor or controller as when i fried the last one it costs $ to replace ( $ which are running out)
I do need to put pressure on all parts as who knows what the purchaser may stupidly do. It needs to be pretty foolproof.( or protected)
Cheers
