FAQ

What is the purpose of the +15V tap on the primary winding?

The +15V tap allows for compensation for voltage drops under load or in long cable runs, ensuring the secondary voltage remains stable. It’s used when the input voltage is consistently lower than the nominal 230V or 400V.

Is this transformer suitable for creating a Separated Extra-Low Voltage (SELV) circuit?

No, this is an isolation and control transformer with a secondary voltage of 115V/230V. To create a SELV circuit, you would need a safety transformer with a secondary voltage not exceeding 50V AC, such as a 24V model.

What are the components mounted on top of the transformer?

The assembly includes several Legrand modular devices, likely from their DX3 series, which serve as circuit breakers or protection relays for the various output circuits. This provides a complete, pre-wired control power distribution solution.
