FAQ

Question?
What is the key difference between this linear power supply (47025) and a modern switch-mode power supply (SMPS)?

Answer: The Legrand 47025 is a linear power supply, using a large, heavy transformer. It’s very robust against line spikes and generates low electronic noise (EMI). A modern SMPS is much lighter, more energy-efficient (less heat), but can be more sensitive to power quality and generate more EMI if not properly filtered.

Question?
The primary input is listed as 230/400V. How do I wire it for my specific voltage?

Answer: The primary side of the transformer has specific terminals or jumpers to configure it for either 230V or 400V input. Always refer to the wiring diagram on the unit or in the official datasheet to ensure correct connection before applying power. Incorrect wiring can permanently damage the unit.

Question?
The label mentions a 16A gG fuse. Is this for the primary or secondary side?

Answer: The fuse holder visible on the unit is typically for the primary (input) side protection. A 16A gG fuse is a general-purpose fuse. It’s crucial to use the specified type and rating to protect the transformer from overcurrents and ensure safe operation.
