Product Information
Full details
This Legrand Bell Transformer (model 413093) is designed for homeowners and electricians needing a reliable power supply for their doorbell systems. Its key benefit is converting standard mains voltage to a safe, low voltage specifically for doorbells, ensuring consistent operation. A minor caveat is its modular design, requiring a distribution cabinet for mounting. This transformer offers dual secondary voltages (24V and 12V) and features integrated short-circuit and overload protection, ensuring safety and durability.

What is the maximum power output of this transformer?
The maximum output power is 18W, with a maximum secondary amperage of 1.5A per output.
Can this transformer be mounted directly to a wall?
Yes, it supports both DIN rail mounting (for 4 modules) and direct wall mounting.
Does this transformer come with a label holder?
A label holder is not included but is available as an optional accessory for labeling purposes.
What safety protections are included?
The transformer is protected against short circuits and overload conditions.
What standards does this transformer conform to?
It conforms to EN/IEC 61558-2-8 standards.
Troubleshooting
Doorbell not receiving power
Verify that the primary voltage (230V) is correctly supplied to the transformer. Check the secondary wiring connections to the doorbell and ensure the correct voltage output (12V or 24V) is selected and connected. Confirm the doorbell itself is functioning correctly.
Transformer overheating or shutting down
This may indicate an overload or short circuit. Disconnect the power, inspect the doorbell wiring for any shorts or damage, and ensure the connected device's power consumption does not exceed the transformer's rated capacity (18W/1.5A). Reset the transformer after the fault is resolved.
Intermittent doorbell operation
Check all wiring connections for tightness and corrosion. Ensure the selected output voltage is appropriate for the doorbell model. Verify there are no other devices on the same circuit that might be causing voltage fluctuations.
Pros and Cons
Pros
- Provides flexibility with dual output voltages (24V/12V).
- Integrated safety features protect against electrical faults.
- Compact 4-module design saves space in electrical panels.
- Suitable for both DIN rail and wall mounting.
- Conforms to recognized safety standards (EN/IEC 61558-2-8).
Cons
- Requires installation within a distribution cabinet or suitable enclosure.
- May require professional installation for users unfamiliar with electrical wiring.
- Only one unit is included per pack.
- Does not include an integrated label holder (optional).
- Potential for confusion with multiple voltage outputs if not properly labeled.
Setup, Compatibility & Care
Setup:
- Mounting: The transformer can be mounted on a standard DIN rail within a distribution cabinet or securely to a wall using appropriate fixings. Ensure it is mounted in a dry, accessible location.
- Wiring: Connect the primary side (230V) to the appropriate circuit breaker in your distribution panel. Connect the secondary side to your doorbell wiring, selecting either the 24V or 12V output as required by your doorbell system. Ensure all connections are secure and comply with local electrical codes.
- Labeling: It is highly recommended to use the optional label holder or clearly label the transformer with its function and output voltages (24V, 12V, 0V) for future reference.
Compatibility:
- This transformer is designed for wired doorbell systems and compatible low-voltage devices that operate within the 12V-24V range.
- It is not suitable for battery-powered doorbells or devices requiring higher voltages.
- Ensure your doorbell system's power requirements do not exceed the transformer's maximum output of 18W or 1.5A per secondary output.
Care:
- Keep the transformer clean and free from dust and debris. Use a dry or slightly damp cloth for cleaning; avoid using solvents or abrasive cleaners.
- Ensure adequate ventilation around the transformer to prevent overheating.
- Periodically check wiring connections for security and signs of corrosion.
