Bronson TT 1000

  • Toroidal transformer with galvanic isolation for the operation and repair of 230 volt appliances
  • Maximum capacity: 1,000 watts
  • Operating capacity: 800 watts
Bronson TT Series isolation transformers are designed to provide maximum power stability, safety and efficiency for a variety of electrical power supply setups utilizing galvanic isolation between primary and secondary sides of the transformer. Available in 500 Watt and 1000 Watt models with EU IEC input cables and EU output sockets and terminal connectors.

Please Note: The AC output sockets are case grounded but can be easily modified to be ungrounded to create a “floating ground” or through using the L,N terminals.

The TT isolation transformers allow the creation of a 230V output AC circuit (secondary circuit of the transformer) isolated from the 230V AC power supply input (primary circuit of the transformer). This can provide protection against electrolytic corrosion in marine applications where it is necessary to isolate a boats on-board circuitry from the shore power grid. The TT series is often used to enhance safety in electrical workbench installations where testing and repair of devices can otherwise create dangerous situations.

The Bronson TT 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 TT 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.
