Mass GI Isolation Transformer, 16 A/3.5 kW

A safe connection between vessel and shore installation is an essential part of your electrical system. A galvanic electrical isolation between shore power and the on board power prevents any electrical corrosion of metal parts while keeping you earthed. Especially important on metal hulled vessels, but offering significant benefits for all boats, Isolation Transformers protect the metal fittings on any boat from potentially dangerous galvanic corrosion.
They do this by electrically isolating the onboard AC sytem from the connected shore power AC system, while still maintaining the safety provided by the shore power AC green grounding wire.

Suitable for 120V and 230V AC systems, rated at 16A/3.5 kVA per unit, up to 4 units can be parallel coupled for higher capacity. Two 16A/3.5 kVA units correspond to 32A/7 kVA, four units give 64 A/14 kW.

Modern transformer technology: Light, silent, reliable and easy
The Mass GI incorporates the latest high-frequency switching technology as well as automatic ramp-up Soft Start to eliminate high inrush currents when connecting to the grid.
The transformer can be remote controlled and has the option of automatically starting the generator when there is an AC current overload.

Units can be parallel coupled for higher capacity
Parallel switching of the Mass GI units increases the AC power capacity.
Two 16 A/3.5 kW units ensure 32 A/7 kW, four units give 64 A/14 kW.
The Mass GI is 75% lighter and 60% smaller than comparable low frequency transformers

Install Anywhere

With its robust aluminium casing, this isolation transformer can be fitted in any position on wall or floor.
No rubber mountings are necessary because the unit does not vibrate or hum.
The Mass GI also features professional connections with strain relief cable glands.
