Bronson MII 1000

  • Toroidal transformer with galvanic isolation for the operation and repair of 230 volt appliances to both 230 and 110 volts of electricity grids
  • Maximum capacity: 1,000 watts
  • Operating capacity: 800 watts
The Bronson MII Series multi input isolation transformers are designed to provide stabilized and isolated 230V output from either 220V-240V European grid power or 100V-120V American grid power. Created to provide enhanced safety using galvanic isolation while maintaining high efficiency for a variety of electrical power supply installations. This transformer allows the creation of a ‘floating’ 230V AC circuit (secondary circuit of the transformer) isolated from the AC power supply (primary circuit of the transformer).

The MII Series provides power pure sine wave conversion from 300 Watt up to 2000 Watt maximum continuous rating achieving 98% by utilizing a high efficiency silicon steel toroidal core. Input & Output can be wired to the terminal connections with additional output socket connections available for both UK and EU socket types.

This can provide protection against electrolytic corrosion in marine applications where boats may travel between 110v and 230v countries. They can also be used as standard isolation transformers in any application where additional protection is required beyond the scope of normal auto transformers or weather corrosion sensitive applications and can enhance safety in electrical workbench installations where testing and repair of devices can otherwise create dangerous situations.

The Bronson MII models achieve 98% transmission efficiency using highly efficient silicon steel toroidal core transformers. Solid build quality and sturdy mounting brackets on the case will enable for use in boating and RV applications.

When operating the Bronson MII models, please ensure that the total rated power (number of watts) of all connected devices does not exceed the maximum rated power of the transformer. Please Note: Individual output sockets will supply a maximum of 16A to any load or combination of loads, while the output terminals will carry a maximum load according to the maximum power rating of the specific model.
