AC Power over tether

(Basil Alias) #1

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 !!

Thankyou Koppel

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:
