Advantages
- Flexible and space-saving due to option of horizontal or vertical mounting
- Low operating temperature due to unimpeded air circulation on all sides
- Safe and simple cable connection achieved through the use of special terminals
- Easy installation using special mounting supports that permit the comfortable use of tools
- Reliability achieved through high standards of quality control carried out by state-of-the-art, calibrated instruments at all stages of production, from receipt of raw materials to inspection of final products, one by one
Applications
Isolating transformers can be used:
- Where galvanic isolation of the load and the user from the power source (e.g. power grid) is required for protective purposes. The supply voltage can be transformed to a different value at the same time
- When the transformer is incorporated in an electrical control panel as a component of a circuit/configuration
Safety isolating transformers can be used:
- When safe extra low voltage (SELV) is required, in addition to isolation
- When the transformer is incorporated in an electrical control panel as a component of a circuit/configuration
- To supply SELV rectifying circuits
