MASTERVOLT izoliacijos keitiklis Mass GI 3.5 kW

The Mastervolt Mass GI 3.5 kW isolation transformer delivers 3500 VA (3.5 kW) at 230 V, and 1920 VA (1.92 kW) at 120 V. It is rated for a nominal current of 16 A.

The Mass GI 3.5 kW uses high-frequency switching mode technology, unlike older low-frequency transformers. This makes it 75 % lighter and 60 % more compact, while providing silent and vibration-free operation.

The Mass GI 3.5 kW isolation transformer weighs 6 kg (7.4 kg with packaging). Its dimensions are 340 x 261 x 144 mm (height x width x depth).

The Mass GI 3.5 kW accepts an input voltage range of 90 to 255 V and provides an output voltage within the same range (90–255 V), with a ±5 % tolerance. It operates at a frequency of 45 to 65 Hz.

Yes, the Mass GI 3.5 kW is compatible with 120 V systems. In this case, the output power is 1920 VA (1.92 kW). It operates within a voltage range of 90 to 255 V, making it suitable for both 120 V and 230 V networks.

The efficiency of the Mass GI 3.5 kW exceeds 93%, which minimizes energy losses and heat generation. Its no-load consumption is only 22 W.

The Mass GI can be mounted in any position on a bulkhead or on the floor, but it is recommended to install it vertically to optimize airflow. It does not require rubber mounts as it does not vibrate. Leave at least 10 cm of space around the unit for ventilation.

Yes, the Mass GI input circuit is equipped with an integrated Soft Start circuit that eliminates high inrush currents when connecting to shore power, thus protecting your installation and the marina’s circuit breaker.

Yes, the Mass GI is compatible with Mastervolt’s MasterBus network. This allows remote control, alarm monitoring, and easy configuration, particularly for parallel operation.

The Mass GI 3.5 kW has an IP23 protection rating, meaning it is protected against water spray and solid objects larger than 12 mm. It must be installed in a ventilated area, sheltered from rain and humidity.

Yes, the Mass GI 3.5 kW is specifically designed for marine applications. It provides galvanic isolation between shore power and the boat’s electrical system, preventing galvanic corrosion of metal parts. It complies with CE and ABYC standards.

For a safe installation, connect both the earth (Protective Earth) and the neutral (N) from the AC output of the Mass GI to the boat's central ground point, which is connected to the hull. Never connect the earth wire from the AC input (shore power) to the AC output or the boat's ground point.

The Mass GI 3.5 kW can operate in an ambient temperature range from 0 °C to 40 °C. Above 40 °C, power output decreases progressively. The device automatically shuts down at 80 °C for protection.

Yes, the Mass GI 3.5 kW can be used with a generator, provided the generator's output voltage and frequency fall within the device's accepted ranges (90-255 V and 45-65 Hz). The Soft Start function prevents high inrush currents at startup.

The delivery includes the Mass GI 3.5 kW isolation transformer, a MasterBus communication cable, a MasterBus terminator, and the user manual. AC power cables are not included.
