Galvanic Isolation & Automatic Input Voltage Detection
Connecting a boat to shore power creates an accidental galvanic battery between the boat's underwater metal fittings (propellers, shafts, through-hulls) and the shore ground or neighboring vessels. The Isolation Transformer physically breaks the shore earth connection while transferring power magnetically through an isolated toroidal winding.
The Victron Isolation Transformer 3600W Auto (ITR050362042) provides marine galvanic isolation with a 3600W toroidal core, automatic AC input switching (115V or 230V), and selectable AC output (120V or 240V at 32A / 16A):
- Shore Power Input: 115V / 230V Auto, 50 / 60 Hz Line, Shore Earth Ends, Overload Protection.
- Toroidal Isolation: 1:1.05 Ratio, Soft-Start Inrush, Low Noise/Weight, -20°C to 40°C.
- Vessel AC Out: 120V / 240V, 32A / 16A, Vessel Earth, IP21 Aluminium.
Installation Rules & Wiring Safety
- Shore Input Earth Termination: Connect the shore earth wire strictly to the transformer's internal shield terminal; never connect shore earth to the vessel hull or vessel safety ground.
- Vessel Neutral-Ground Bonding: Bond the secondary output neutral conductor to the vessel central grounding plate to ensure proper operation of onboard RCD / GFCI breakers.
- Automatic Detection: The unit automatically senses AC input voltage * 115 or 230V, automatic detection across Frequency 50/60Hz, outputting AC output voltage * 120 or 240V with Output current rating 32A (115V) 16A (230V).
Soft Start Protection & Toroidal Design
The Isolation Transformer 3600W Auto incorporates specialized marine protection features:
- Inrush Current Limiting: Toroidal transformers have high magnetic inrush currents upon energization. The integrated Soft start Yes circuit limits starting current to prevent tripping sensitive marina shore breakers.
- Toroidal Efficiency: Built with a Transformer type Toroidal (low noise, low weight), 1:105 ratio for quiet, hum-free operation in living quarters.
- Aluminum Chassis: Housed in an Enclosure Aluminium (blue RAL 5012) with Protection category IP21, weighing Weight 217 kg with Dimensions (h x w x d), mm 362 x 258 x221.
- Thermal Envelope: Operates across Operating temperature range -20°C to 40°C for all Isolation Transformer - ITR050362042 3600W auto 115/230V installations.
