We are planning to power ROV using an External power supply using an Ac to DC converter inside the ROV instead of a battery. So, is it possible to supply AC voltage(230v @ 6Amps) through twisted pairs by combining 3 pairs(2 Amps on each pair) parallelly??
I do similar solution, 2 amps 240V AC on two pairs, one pair phase, one pair neutral in 100 m tether.
Using 25A converter onboard and current limiting in ROV parameters.
NOTE!! really dangerous regarding electric safety even with GFCI breaker !!
What power supply are you thinking of using? I am looking into this also.
The budget 25 Amp has to be cut a bit in the corners (!!!), but works very good:
If You not like to cut a 240 V Powersupply (You really shouldnt) there is 16 Amp that fits right off:
