Mastervolt Isolation Transformers - Mass GI, IVET-D & IVET Heavy Duty From shore power to onboard network You need to be careful when introducing shore power onboard, especially when the yacht is made of aluminium or steel. An incorrectly configured system can result in electrolysis, which will slowly but surely corrode the metal components. It is also important to protect the engine, rudder, rudderstock, propeller and thruster on composite yachts. A Mastervolt isolation transformer will help preserve your valuable boat and provide you with the security of a correctly earthed 230V system. Select the right transformer for your system: Lightweight Mass GI transformer - Ultra modern high frequency electronic switch technology - Lightweight and compact - Integrated Soft Start function - Connect to power from 90?255V and from 45?65Hz - Units can be parallel coupled for higher capacity - Higher efficiency, limited heat development IVET-D isolation transformers - High quality toroidal transformer in robust casing, including circuit breaker - Standard Soft Start for the suppression of inrush current at shore connection - Multi tap version for both 230V/50Hz and 120V/60Hz shore voltage IVET heavy-duty series - High-quality isolation transformers without casing (for self installation) - Optional Soft Start, in synthetic casing - Capacities of 25?22kW Modern transformer technology: Light, silent, reliable and easy Mastervolt?s Mass GI offers the latest high frequency switching technology as well as Soft Start for peak loads when connecting to the shore. Weighing a mere six kilograms, LED lights on the casing indicate load and overload. The transformer can be remote controlled via a panel and has the option of automatically starting the generator when there is a shore current overload. Higher capacity via parallel switching Parallel switching of the Mass GI units increases the shore power capacity. Two 16A/3.5kW units ensures 32A/7kW, four units give 64A/14kW. Global solution The IVET-D multi-tap is suitable for 230V/50Hz and 120V/60Hz (American or Caribbean). Install anywhere With its maritime, aluminium casing, this isolation transformer can be fitted in any position on a 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. Practical tips: - Determine shore and onboard current: 230V, 120V or both - Determine the capacity. Maximum load with onboard power usage: amount of amps and kW - Note sizes and weight; the mass GI is 75% lighter and 60% smaller compared to low frequency transformers Remember: - Detection system for IVET heavy duty automatically supplies onboard system with 230V in case of a 120V/60Hz shore connection (or vice versa) - Systemswitch or Masterswitch for integrating shore power, generator and/or inverter - Connects to 12V or 24V system, battery charger or Mass Combi Mastervolt Isolation Transformers BLA Code 111262 Description Mass GI 7 Input Input voltage 90?255V Input frequency 45?65Hz Nominal input current at 230V 32A No load consumption 44 W Earth leakage protection no Output Output voltage (equal to input) 90?255V, ± 5% Output frequency (equal to input) 45?65Hz Soft Start yes Switch off behaviour breaker B-characteristic Efficiency >93% General Specifications: Power 7000 W* Technology high frequency Dimensions, HxWxD mm 340x261x250 Weight kg 10 Ambient temperature 0?40°C, derating with 5% per °C (40?60°C) / 32?104°F, derating with 5% per °F (104?140°F) Switch off at 80°C / 176°F Cooling variofan Operating humidity max. 95% Protection degree IP23 MasterBus compatible *Up to 4 units parallel (14kW).
