You need to be careful when introducing shore power on board, for safety reasons and to protect your yacht, especially if she is made of aluminium or steel. An inadequate configuration of your on board system can result in electrolysis, leading to slow but sure corrosion of the metal components. A Mastervolt isolation transformer will help preserve your valuable boat and provide you with security through a correctly earthed AC power system.

The Mass GI is an extremely small and light isolation transformer supplied with the latest high-frequency electronics switch technology. Suitable for 120 V and 230 V AC systems, its capacity can be parallel coupled for higher capacity. Two units correspond to double its size. This isolation transformer can be fitted in any position on a wall or floor. No rubber mountings are necessary because it does not vibrate or hum. The integrated Soft Start manages the current resulting from connection to the shore.

A LED indicator on the box displays load data. Remote operation is possible via any MasterBus panel. There is also a connection for the automatic activation of the generator if shore power is overloaded. The Mass GI features marine aluminium casing and professional connections with strain relief cable gland. All Mastervolt isolation transformers comply with the CE and ABYC (US norm) guidelines for vessels.
